About the Analyst
This pricing analysis was compiled by Matthew Gigantelli, a cost segregation engineer and process architect who has personally toured and completed engineered studies on over 3,000 properties — from single-family rentals to heavy manufacturing facilities and commercial buildings valued at over $100 million. Gigantelli holds a B.A. in Finance (summa cum laude) from Rasmussen University and a certification from Boon Tax Educators (2026). He has spent the past four-plus years engineering cost segregation studies across every major property type in the United States.
Over the course of those 3,000+ engagements, Gigantelli has reviewed competitor proposals, seen pricing from every major firm type, and tracked what investors actually pay versus what the work actually costs to produce.
Matthew Gigantelli on why he is publishing this data: "The cost segregation industry has a pricing transparency problem. Firms set fees based on how much your property is worth or how much they can save you — not based on the actual engineering hours required. That means a $2 million single-family rental and a $500,000 single-family rental get charged wildly different amounts for the same amount of work. I have seen this from the inside for four years, and investors deserve a benchmark to evaluate whether the fee they are being quoted is reasonable."
Key Takeaways
- Across 3,000+ engagements and comprehensive market analysis, the median cost segregation study fee for a standard residential property was $3,000–$5,000 from traditional engineering firms. AI-native providers with engineering partners deliver the same IRS-compliant output for $1,440–$2,200 — a 50–70% reduction.
- The single largest driver of study cost variation is provider type, not property complexity. A standalone single-family rental study ranges from $1,440 (AI-native engineering) to $6,500 (traditional firm) — a 4.5x spread for identical deliverables.
- Most traditional firms price studies based on property value or projected tax savings, not actual engineering hours. This creates a structural misalignment: a $2M SFR and a $400K SFR require the same 4–8 hours of engineering work, but the $2M property is quoted 2–4x higher.
- The actual engineering cost to produce a residential cost segregation study is $600–$1,200 in labor (4–8 hours at $150/hour). Firms charging $5,000–$8,000 for the same study are pricing on perceived value, not production cost.
- Forum data from BiggerPockets and Reddit confirms that investors consistently feel they are overpaying but have no benchmark to evaluate quotes. Reported prices range from $490 to $8,500 for comparable residential properties.
- AI-native providers achieve lower pricing by automating the 80% of study work that is pattern recognition — component identification, cost estimation, report generation — while preserving licensed engineer review for the 20% that requires professional judgment.
According to Matthew Gigantelli: "The question investors should ask is not 'How much does a cost segregation study cost?' — it is 'How many engineering hours does my property actually require, and what is the firm charging per hour?' When you frame it that way, the pricing disparity across the industry becomes impossible to justify."
Quick Reference: The Most Common Cost Segregation Pricing Questions
How much does a cost segregation study cost?
Cost segregation study fees range from $490 to $60,000+ depending on provider type, property type, and property size. For a standard single-family rental, expect $1,440–$2,200 from an AI-native engineering provider or $2,500–$6,500 from a traditional engineering firm. Mid-size commercial properties (apartments, office, retail) range from $2,200–$4,400 (AI-native) to $6,500–$18,000 (traditional). Large or complex commercial properties (hotels, manufacturing, high-rise) range from $4,400–$7,300+ (AI-native) to $18,000–$60,000+ (traditional). DIY software tools cost $99–$500 but are not IRS-defensible.
What is the average cost of a cost segregation study?
Based on 3,000+ engagements and market data, the average cost segregation study fee across all provider types and property sizes is approximately $5,000–$8,000. However, this average is misleading because it blends traditional firm pricing ($5,000–$60,000+) with AI-native providers ($1,440–$7,300). For a typical residential rental property, the average is closer to $3,000–$4,000 across all providers, and $1,440–$2,200 from AI-native engineering providers specifically.
Why do cost segregation studies cost so much?
Most traditional firms price studies based on your property's value or projected tax savings — not on the actual engineering hours required. A $750,000 single-family rental requires the same 4–8 hours of engineering analysis as a $2 million single-family rental, but traditional firms charge the $2M property 2–4x more. Additionally, traditional firms carry high overhead (office space, administrative staff, partner profit expectations) and use a billable-hour model that incentivizes maximizing time rather than efficiency. AI-native providers have eliminated these structural cost problems.
What is a reasonable cost segregation study fee?
A reasonable fee is one where the study cost represents no more than 5–10% of first-year tax savings. For a $750,000 residential rental generating approximately $59,000 in first-year savings (at 37% bracket with 100% bonus depreciation), a reasonable study fee is $1,500–$5,900. At Overline's pricing ($1,800 for a standalone SFR), the fee represents approximately 3% of first-year savings — a 33x ROI. At traditional pricing ($5,000–$8,000), the fee represents 8–14% of savings — still positive ROI, but significantly less efficient.
Is a $500 cost segregation study legitimate?
It depends on what you are getting. A $490–$500 study from a software-only provider (no engineer review, no site-specific analysis) is a screening tool, not an IRS-defensible study. It uses template percentages applied to your purchase price. If audited, the IRS will compare those generic allocations to your actual property — and templates do not hold up. A $1,440+ study from an AI-native provider with licensed engineer review is legitimate. The AI handles pattern recognition and data collection; the engineer reviews every classification. The deliverable is the same IRS-compliant report a traditional firm produces. The price difference reflects efficiency, not quality. For a detailed breakdown of what separates legitimate studies from scams, see our cost segregation scams guide.
Should I pay a percentage-based fee for cost segregation?
No. Percentage-based (contingency) fees — where the firm charges a percentage of your tax savings — create a structural conflict of interest. The firm is incentivized to maximize your reclassification percentage, which means more aggressive classifications that may not survive an IRS audit. A flat fee based on property type and complexity aligns the provider's incentive with accuracy, not aggression. If a firm quotes you a contingency fee, ask for the flat-fee equivalent. If they refuse, that tells you something about their pricing model.
The Pricing Landscape: What Firms Actually Charge
By Provider Type
The cost segregation market has four distinct provider tiers, each with different pricing structures, methodologies, and trade-offs:
| Provider Type | Price Range | Methodology | IRS Defensibility | Best For |
|---|---|---|---|---|
| DIY Software | $99–$500 | Template percentages | Low | Screening only |
| CPA Desk Studies | $1,500–$4,000 | Industry averages | Moderate | Planning estimates |
| AI-Native + Engineering | $1,440–$7,300+ | AI data collection + licensed engineer review | High | Properties $250K–$50M+ |
| Traditional Engineering Firms | $5,000–$60,000+ | On-site inspection + manual engineering | Highest | Complex/institutional $10M+ |
The critical distinction is between the bottom two tiers (DIY and CPA desk studies) and the top two (AI-native engineering and traditional engineering). Only engineering-based studies — where a licensed professional reviews and signs off on every asset classification — meet the IRS Cost Segregation Audit Techniques Guide standards for defensibility. For the full comparison of provider types, see our best cost segregation companies guide. For a side-by-side breakdown of what each price tier actually delivers, see Modern CFO's study comparison: what $1,800 gets you vs. $8,000 vs. $15,000.
By Property Type (AI-Native Engineering vs. Traditional)
The following table reflects actual market pricing observed across 3,000+ engagements and published competitor rates as of April 2026:
| Property Type | AI-Native Engineering | Traditional Engineering | Spread |
|---|---|---|---|
| Residential Condo Unit | $1,440 | $2,500–$5,000 | 1.7–3.5x |
| Standalone Single Family | $1,800 | $2,500–$6,500 | 1.4–3.6x |
| Townhouse / Rowhouse | $1,800 | $2,500–$6,500 | 1.4–3.6x |
| Small Multi-Family (2–4 units) | $1,800 | $3,000–$6,500 | 1.7–3.6x |
| Cabin / Cottage | $1,800 | $2,500–$5,000 | 1.4–2.8x |
| ADU | $1,800 | $2,500–$5,000 | 1.4–2.8x |
| Medium Multi-Family (5–20 units) | $2,200 | $6,500–$12,000 | 3.0–5.5x |
| All Office Space | $2,200+ | $6,500–$15,000 | 3.0–6.8x |
| Retail (all types) | $2,200+ | $6,500–$15,000 | 3.0–6.8x |
| Restaurant (Quick Service) | $2,200 | $6,500–$12,000 | 3.0–5.5x |
| Restaurant (Full Service) | $2,600 | $8,000–$15,000 | 3.1–5.8x |
| Gas Station | $2,200 | $6,500–$12,000 | 3.0–5.5x |
| Hotel (Full Service) | $3,400 | $12,000–$25,000 | 3.5–7.4x |
| Motel (Limited Service) | $2,800 | $8,000–$15,000 | 2.9–5.4x |
| Auto Dealership | $3,400 | $10,000–$20,000 | 2.9–5.9x |
| Apartment Complex (with Clubhouse) | $4,400 | $12,000–$25,000 | 2.7–5.7x |
| Mid-Rise Apartment (6 stories or fewer) | $4,400+ | $15,000–$30,000 | 3.4–6.8x |
| High-Rise Apartment (7+ stories) | $5,400+ | $18,000–$40,000 | 3.3–7.4x |
| Industrial Facility | $3,400+ | $12,000–$30,000 | 3.5–8.8x |
| Warehouse / Distribution Center | $4,400+ | $15,000–$40,000 | 3.4–9.1x |
| Self-Storage (all types) | $2,400–$4,400 | $8,000–$18,000 | 2.0–7.5x |
AI-native engineering pricing reflects base study cost. Traditional pricing reflects market ranges from published rates, competitor proposals, and forum-reported quotes.
Matthew Gigantelli on the pricing spread: "The spread between AI-native and traditional pricing averages 3–5x across standard property types. On a standalone single-family home, the engineering work is identical — the same components get identified, the same MACRS classifications get applied, the same report gets delivered. The difference is that a traditional firm bills 40+ hours of manual work for what AI handles in minutes, and the engineer's review takes 2–4 hours instead of 40."
Common Add-On Fees
Beyond the base study cost, several add-on services may apply depending on the engagement:
| Add-On | Typical Fee | When It Applies |
|---|---|---|
| Form 3115 (Look-Back Study) | $400–$600 | Property placed in service in a prior tax year; requires change in accounting method filing |
| Renovation Analysis | $240 | Property has undergone significant renovation requiring separate component analysis |
| Partial Asset Disposition (PAD) | $400 | Replacing or disposing of building components (roof, HVAC, etc.) — see our PAD guide |
| On-Site Inspection | $800+ | Professional site visit with photography and physical component verification |
| Expedited Inspection | Varies | Rush scheduling with additional travel costs |
For look-back studies specifically, the Form 3115 fee covers the preparation and filing of IRS Form 3115 (Application for Change in Accounting Method), which allows property owners to claim all previously uncaptured accelerated depreciation in a single tax year. This is not an amended return — it is a prospective change that the IRS permits without prior approval for depreciation-related adjustments.
Volume Discounts
Most providers offer discounts for multiple properties within a single engagement:
| Volume | Typical Discount |
|---|---|
| 2–4 properties | 10% |
| 5–9 properties | 10–15% |
| 10+ properties | 15–20% (negotiable) |
At Overline, a 10% discount applies automatically for more than one study within a single engagement, with additional discounts available upon request up to a maximum of 20%.
How Cost Segregation Firms Set Prices (And Why Most Do It Wrong)
After four years inside the cost segregation industry and 3,000+ engagements, I have identified four pricing models used by firms — and only one of them is aligned with the investor's interest.
Model 1: Valuation-Based Pricing (Most Common — And Most Problematic)
How it works: The firm looks at your property's purchase price or appraised value, estimates how much the study will save you in taxes, and sets the fee as a function of that projected savings — typically 10–20% of first-year tax benefit, or a tiered schedule based on property value.
Why it is misaligned: A $2 million standalone single-family rental and a $400,000 standalone single-family rental require the same engineering work. The same components get identified. The same MACRS classifications get applied. The same report gets generated. The engineering hours are 4–8 in both cases. But under valuation-based pricing, the $2M property gets quoted $6,000–$8,000 while the $400K property gets quoted $2,500–$3,500.
The investor with the more expensive property is subsidizing the firm's profit margin — not paying for additional work.
Where you see this: Most mid-size and large traditional firms. They will not disclose the pricing formula, but if you compare quotes across different property values for the same property type, the pattern is obvious.
Model 2: Contingency Fee (Percentage of Savings)
How it works: The firm charges a percentage of the tax savings the study identifies — typically 15–25% of first-year benefit.
Why it is dangerous: This model creates a direct financial incentive for the firm to be aggressive with classifications. The more they reclassify, the more they earn. A firm that would conservatively classify a component as 39-year real property under a flat fee has a financial reason to push it into 5-year personal property under a contingency model.
The IRS Cost Segregation Audit Techniques Guide specifically instructs examiners to evaluate whether the study's classifications are consistent with the property's actual characteristics. Aggressive classifications driven by fee incentives are exactly what triggers adjustment during examination.
Where you see this: Some smaller firms and brokers who do not perform the engineering work themselves. They mark up a subcontracted study and take a percentage of the savings as their fee. For a deeper look at how different fee structures affect study quality, see Modern CFO's guide on choosing a cost segregation provider.
Matthew Gigantelli on contingency fees: "I have reviewed studies produced under contingency arrangements where the reclassification percentage was 35–40% on a standard apartment building — well above the 22–28% interquartile range from 8,000+ studies. When I asked about the methodology, the answer was always some variation of 'we found more than other firms.' That is not a methodology. That is a fee structure masquerading as engineering."
Model 3: Hourly Billing (Big Four and Large Firms)
How it works: The firm bills by the hour at rates of $150–$350/hour, with junior engineers doing the bulk of the work and senior partners reviewing.
Why it is inefficient: The billable-hour model incentivizes maximizing time, not efficiency. A junior engineer spending 40 hours manually categorizing components that AI identifies in 10 minutes is not delivering more value — they are generating more billable hours.
A typical traditional-firm study breakdown: junior engineer (40 hours at $150/hr = $6,000) + senior review (8 hours at $250/hr = $2,000) + report writing (6 hours at $175/hr = $1,050) + overhead markup = $12,000–$15,000 total.
Where you see this: Big Four accounting firms, large national engineering firms, and regional firms with legacy billing structures.
Model 4: Flat Fee by Property Type and Complexity (The Right Model)
How it works: The fee is determined by the asset class and building size — the two factors that actually drive engineering hours. A standalone single-family home costs the same whether it is worth $400K or $4M, because the engineering work is the same. Larger or more complex properties cost more because they require more engineering hours.
Why it is aligned: Flat-fee pricing eliminates the incentive to inflate classifications (contingency), the incentive to maximize hours (hourly), and the inequity of charging based on property value rather than work performed (valuation-based). The investor knows the cost upfront, and the provider's incentive is to deliver accurate, defensible work efficiently.
Where you see this: AI-native engineering providers (including Overline) and some progressive traditional firms.
Matthew Gigantelli on flat-fee pricing: "Every study I deliver is priced based on what the property requires in engineering hours — not what it is worth. A townhouse is a townhouse. A 20-unit apartment building is a 20-unit apartment building. The fee reflects the work, not the investor's net worth. That is how engineering services should be priced."
What a Cost Segregation Study Actually Costs to Produce
This is the data the industry does not publish. After engineering 3,000+ studies, I can break down exactly what each phase of a cost segregation study costs in actual labor and resources.
Cost Breakdown: Standard Residential Property (SFR, Duplex, Small Multi-Family)
| Phase | Traditional Firm | AI-Native Engineering | What Happens |
|---|---|---|---|
| Data Collection | 8–12 hrs ($1,200–$1,800) | 15 min (AI-automated) | Property records, imagery, construction data, owner-provided photos |
| Site Inspection | 4–6 hrs ($600–$900) + travel | Optional ($800 when warranted) | Physical walkthrough, component photography, measurements |
| Component Identification | 12–16 hrs ($1,800–$2,400) | 20 min (AI) + 1 hr (engineer review) | Identifying every depreciable component in the building |
| Cost Estimation | 8–12 hrs ($1,200–$1,800) | 10 min (AI) + 30 min (engineer review) | Assigning costs using RS Means, Marshall & Swift, or contractor data |
| MACRS Classification | 4–6 hrs ($600–$900) | 10 min (AI) + 1 hr (engineer review) | Classifying each component into 5-year, 15-year, or real property |
| Report Generation & QA | 6–8 hrs ($900–$1,200) | 15 min (automated) + 30 min (engineer review) | Depreciation schedules, documentation, final review |
| Total Labor | 42–60 hours | 3–4 engineer hours | |
| Total Labor Cost | $6,300–$9,000 | $450–$600 | |
| Overhead & Margin | 30–50% markup | Minimal overhead | Office, admin, partner profit vs. lean operation |
| Final Fee to Investor | $8,000–$13,500 | $1,800 |
The gap between production cost and investor fee is where the industry's pricing opacity lives. A traditional firm's $8,000 fee on a residential study includes $6,300–$9,000 in actual labor plus 30–50% overhead and profit markup. An AI-native provider's $1,800 fee includes $450–$600 in engineer labor plus technology costs and a sustainable margin.
The deliverable is the same: an IRS-compliant engineering-based cost segregation study with component-level detail, MACRS classifications, depreciation schedules, and audit defense documentation. For more on why these production cost differences exist, see Modern CFO's breakdown of why studies cost 50% less with the AI-native approach.
Cost Breakdown: Mid-Size Commercial Property (20-Unit Apartment, Office Building, Retail Center)
| Phase | Traditional Firm | AI-Native Engineering |
|---|---|---|
| Data Collection | 12–20 hrs ($1,800–$3,000) | 30 min (AI-automated) |
| Site Inspection | 6–10 hrs ($900–$1,500) + travel | Optional ($800–$1,200 when warranted) |
| Component Identification | 20–30 hrs ($3,000–$4,500) | 30 min (AI) + 2 hrs (engineer review) |
| Cost Estimation | 12–16 hrs ($1,800–$2,400) | 15 min (AI) + 1 hr (engineer review) |
| MACRS Classification | 6–8 hrs ($900–$1,200) | 15 min (AI) + 1.5 hrs (engineer review) |
| Report Generation & QA | 8–12 hrs ($1,200–$1,800) | 20 min (automated) + 1 hr (engineer review) |
| Total Labor | 64–96 hours | 5.5–7 engineer hours |
| Total Labor Cost | $9,600–$14,400 | $825–$1,050 |
| Final Fee to Investor | $12,000–$20,000 | $2,200–$4,400 |
Matthew Gigantelli on production costs: "When I started in this industry, I spent 40+ hours on a single residential study doing everything manually — pulling property records, measuring from satellite imagery, pricing every component from RS Means, writing the report from scratch. Now, with AI handling the data collection and pattern recognition, I spend 3–4 hours on the same study reviewing classifications and applying engineering judgment to edge cases. The quality is the same. The hours are not. And the investor should benefit from that efficiency, not the firm's profit margin."
What Investors Are Actually Paying: Real Forum Data
The cost segregation industry's pricing opacity means investors rely on forums and peer networks to benchmark what they should pay. Here is what real investors report paying, compiled from BiggerPockets, Reddit, and investor communities:
BiggerPockets Forum Reports
Investor in Los Angeles ($1.425M property): Quoted $7,500 for a study projecting $260,000 in bonus depreciation. Their response: "Even though this is tax deductible, this seems like a lot to pay." At Overline's pricing for a standalone SFR ($1,800), the same study would cost 76% less.
Experienced investor (19 years, 6,000+ community votes): On large apartment complexes: "We'll typically spend about $8,000 to get one of these done." He also noted that a colleague "did a full engineering study on the first three [similar properties], found they were all about the same, and then used 'Rule of Thumb' for the others" — a methodology the IRS explicitly warns against in the Audit Techniques Guide.
New investor evaluating properties at $140K–$160K: Asked whether cost segregation made sense at that price point. Multiple respondents advised that traditional study fees ($5,000+) would make cost segregation uneconomical at that property value. With AI-native pricing starting at $1,440, the math changes — though the ROI should still be evaluated carefully at lower property values. See our guide on whether cost segregation is worth it for the full decision framework.
Reddit Reports (r/realestateinvesting, r/tax, r/AdvancedTaxStrategies)
- Users report studies typically identifying 20–30% of property value as eligible for accelerated depreciation, consistent with the 22–28% interquartile range from 8,000+ studies
- Reported pricing for software-only studies: $490–$1,295 from various DIY platforms
- Reported pricing for full engineering studies: $5,000–$12,000 for residential and small commercial
- Common sentiment: investors feel they are overpaying but have no benchmark to evaluate quotes — see Modern CFO's analysis of how much cost segregation actually saves for savings context alongside these costs
- Multiple users recommend getting 2–3 quotes before committing
The Pattern
Across hundreds of forum posts, three themes emerge consistently:
- Investors have no pricing benchmark. They receive a quote, feel it is high, but have nothing to compare it against except anecdotal reports from other forum users.
- Traditional pricing makes cost segregation uneconomical for smaller properties. At $5,000–$8,000 per study, properties under $500K–$750K have marginal ROI — which is why cost segregation was historically reserved for institutional investors.
- Investors conflate low price with low quality. Forum discussions frequently assume that a $500 study must be inferior to a $7,500 study. The reality is that the $500 software-only study IS inferior (no engineer, no defensibility), but a $1,800 AI-native engineering study delivers the same methodology and defensibility as the $7,500 traditional study.
The Transparency Problem: What Firms Hide vs. What You Should Demand
What Most Firms Do Not Disclose
| Hidden Information | Why It Matters |
|---|---|
| Actual engineering hours | You cannot evaluate whether the fee is reasonable without knowing the labor input |
| Pricing formula | Valuation-based pricing is invisible unless you compare quotes across different property values |
| Who reviews the study | Some firms outsource engineering review to subcontractors with no accountability to you |
| Markup percentage | The gap between production cost and your fee is the firm's profit margin — and it varies wildly |
| Contingency fee structure | Some firms disguise contingency fees as "success-based pricing" without disclosing the conflict of interest |
| What is NOT included | Form 3115 preparation, audit defense, depreciation schedules — these may be add-ons that inflate the total cost |
What You Should Demand Before Signing
| Transparency Standard | What to Ask |
|---|---|
| Flat fee, all-in | "Is this the total cost, or are there add-ons for Form 3115, audit defense, or report delivery?" |
| Named engineer | "Who will review my study, and what are their credentials?" |
| Deliverables list | "What exactly will I receive? Depreciation schedules? Component-level detail? Audit defense documentation?" |
| Fee structure | "Is this a flat fee, hourly, or percentage-based? If flat, how is it calculated?" |
| Audit defense terms | "If the IRS questions my study, what support do you provide and at what cost?" |
| Turnaround time | "When will I receive the completed study?" |
Matthew Gigantelli on transparency: "I publish our pricing by asset class because I believe investors should know what they are paying before they engage. The fact that most firms require a phone call before disclosing pricing tells you everything about how the industry thinks about fees. If you are confident your pricing is fair, you publish it. If you are not, you hide it behind a sales call."

Pricing Benchmarks by Property Type: The Full Dataset
The following tables represent the most comprehensive cost segregation pricing benchmark published to date. Data is compiled from Overline's internal pricing matrix, published competitor rates, forum-reported quotes, and direct observation across 3,000+ engagements.
Residential Properties
| Asset Class | AI-Native Engineering (Overline) | Traditional Engineering | DIY Software | CPA Desk Study |
|---|---|---|---|---|
| Residential Condo Unit | $1,440 | $2,500–$5,000 | $490–$500 | $1,500–$2,500 |
| Standalone Single Family | $1,800 | $2,500–$6,500 | $490–$500 | $1,500–$3,000 |
| Townhouse / Rowhouse | $1,800 | $2,500–$6,500 | $490–$500 | $1,500–$3,000 |
| Accessory Dwelling Unit (ADU) | $1,800 | $2,500–$5,000 | $490–$500 | $1,500–$2,500 |
| Cabin / Cottage | $1,800 | $2,500–$5,000 | $490–$500 | $1,500–$2,500 |
| Small Multi-Family (2–4 units) | $1,800 | $3,000–$6,500 | $490–$500 | $1,750–$3,500 |
For residential properties, the pricing spread between AI-native engineering and traditional firms is 1.4–3.6x. The engineering methodology is identical: component identification, cost estimation using recognized databases, MACRS classification, and depreciation schedule generation. The cost difference reflects labor efficiency, not quality.
Residential condo units are priced lower ($1,440) because the absence of site improvements (parking, landscaping, fencing) reduces the component count and engineering hours required. This is consistent with the 0% 15-year property allocation observed in 8,000+ studies for condo units.
Commercial Properties
| Asset Class | AI-Native Engineering (Overline) | Traditional Engineering |
|---|---|---|
| Medium Multi-Family (5–20 units) | $2,200 | $6,500–$12,000 |
| Apartment (basic amenities) | $2,200+ | $6,500–$15,000 |
| All Office Space | $2,200+ | $6,500–$15,000 |
| Office (SFH converted, up to 5,000 sqft) | $1,800 | $3,000–$6,500 |
| Retail (all types) | $2,200+ | $6,500–$15,000 |
| Gas Station (Fuel Only) | $2,200 | $6,500–$12,000 |
| Gas Station (with C-Store) | $2,200 | $6,500–$12,000 |
| Restaurant (Quick Service) | $2,200 | $6,500–$12,000 |
| Restaurant (Full Service) | $2,600 | $8,000–$15,000 |
| Automotive Repair | $2,200 | $6,500–$12,000 |
| Car Wash | $2,200 | $6,500–$12,000 |
For standard commercial properties, the AI-native pricing advantage is most pronounced. A medium multi-family study at $2,200 versus $6,500–$12,000 traditional represents a 3–5.5x spread. The engineering complexity is moderate — more components than residential, but the same systematic identification and classification process.
Office space pricing includes a cost factor for larger buildings: $30 per 1,000 square feet over 10,000 sqft. A 180,000 sqft office building, for example, would be priced at $2,200 base + $5,100 size factor = $7,300 — still well below the $15,000–$40,000 a traditional firm would charge for the same building.
Large and Specialty Properties
| Asset Class | AI-Native Engineering (Overline) | Traditional Engineering |
|---|---|---|
| Apartment Complex (with Clubhouse) | $4,400 | $12,000–$25,000 |
| Mid-Rise Apartment (6 stories or fewer) | $4,400+ | $15,000–$30,000 |
| High-Rise Apartment (7+ stories) | $5,400+ | $18,000–$40,000 |
| Hotel (Full Service) | $3,400+ | $12,000–$25,000 |
| Motel (Limited Service) | $2,800 | $8,000–$15,000 |
| Resort | $4,400+ | $18,000–$40,000 |
| Auto Dealership | $3,400 | $10,000–$20,000 |

| Country Club | $4,400+ | $15,000–$30,000 |
| RV Park / Campground | $2,200+ | $6,500–$15,000 |
For large and specialty properties, the pricing spread widens further. A full-service hotel study at $3,400 (AI-native) versus $12,000–$25,000 (traditional) represents a 3.5–7.4x difference. At these property sizes, the absolute dollar savings from choosing an AI-native provider can exceed $10,000–$20,000 per study.
Properties with discretionary pricing (marked with "+") may incur additional fees based on building size, complexity, or the need for on-site inspection. The base prices shown represent starting points for standard properties within each asset class.
The ROI Reality Check: Study Cost as a Percentage of Savings
The ultimate test of whether a study fee is reasonable is the return on investment. The following table compares ROI across provider types for common property values, using the 24% median accelerated allocation from 8,000+ studies, 100% bonus depreciation, and a 37% tax bracket:
| Purchase Price | Depreciable Basis (80%) | Year-1 Tax Savings (37%) | AI-Native Fee | AI-Native ROI | Traditional Fee | Traditional ROI |
|---|---|---|---|---|---|---|
| $300,000 | $240,000 | ~$21,300 | $1,800 | 11.8x | $5,000 | 4.3x |
| $500,000 | $400,000 | ~$35,500 | $1,800 | 19.7x | $5,500 | 6.5x |
| $750,000 | $600,000 | ~$53,300 | $1,800 | 29.6x | $7,000 | 7.6x |

| $1,500,000 | $1,200,000 | ~$106,600 | $2,200 | 48.5x | $10,000 | 10.7x |
| $2,000,000 | $1,600,000 | ~$142,100 | $2,200 | 64.6x | $12,000 | 11.8x |
| $3,000,000 | $2,400,000 | ~$213,100 | $3,400 | 62.7x | $15,000 | 14.2x |
| $5,000,000 | $4,000,000 | ~$355,200 | $4,400 | 80.7x | $20,000 | 17.8x |
Assumptions: 20% land value, 24% baseline accelerated allocation, 100% bonus depreciation (per the One Big Beautiful Bill Act), 37% combined federal marginal tax rate.
At AI-native pricing, cost segregation delivers positive ROI for properties as small as $250,000 in purchase price. At traditional pricing, the breakeven threshold is closer to $400,000–$500,000.

Why AI-Native Providers Can Charge 50–70% Less
The pricing gap between AI-native engineering providers and traditional firms is not a quality gap — it is an efficiency gap. Here is exactly where the cost savings come from:
The 80/20 Split
Approximately 80% of cost segregation work is pattern recognition: identifying standard building components (carpet, cabinets, parking lots, specialty electrical), estimating their costs from construction databases, and classifying them into MACRS recovery periods. This work follows established rules and precedent. AI handles it in minutes using data from thousands of completed studies.
The remaining 20% requires professional engineering judgment: evaluating edge-case components, applying the Whiteco permanency test to borderline classifications, assessing property-specific construction methods, and reviewing the final report for accuracy and defensibility. This is where licensed engineers add irreplaceable value.
Traditional firms bill 40–60 hours of human labor for both the 80% and the 20%. AI-native providers bill 3–7 hours of engineer time for the 20% that matters. The deliverable is the same. The cost is not.
Structural Cost Advantages
| Cost Factor | Traditional Firm | AI-Native Provider |
|---|---|---|
| Office overhead | Corner offices, administrative staff | Remote/lean operations |
| Partner profit expectations | 30–50% margin targets | Sustainable margins, volume-based |
| Billable hour incentive | More hours = more revenue | Flat fee = efficiency incentive |
| Junior engineer labor | 40+ hrs at $150/hr per study | AI replaces junior labor |
| Cross-selling pressure | Cost seg as loss leader for advisory | Cost seg as core product |
| Travel costs | Mandatory site visits for all studies | Site visits when warranted |
The AI-Forward Partner Model
Overline works exclusively with AI-forward engineering partners — licensed professionals who have integrated AI tools into their workflow and can deliver the same engineering rigor in a fraction of the time. We do not work with firms that still operate on a fully manual, billable-hour model. This selectivity is what enables our pricing: our partners are efficient because they have adopted the same technology philosophy we have.
Matthew Gigantelli on the partner model: "I have personally completed over 3,000 engineered studies. The difference between my first year — doing everything manually — and today is not that I know more about MACRS classifications. It is that AI handles the data collection, component identification, and cost estimation that used to consume 80% of my time. I spend my hours on the engineering judgment that actually matters. That is why our studies cost less. Not because we do less work — because we do the same work in less time."
When to Pay More (And When Not To)
Transparency means acknowledging when traditional pricing is justified:
When Traditional Firm Pricing May Be Worth It
- Highly specialized properties ($25M+ hospitals, semiconductor manufacturing, data centers) where domain-specific construction expertise adds value beyond standard engineering analysis
- Institutional lender requirements where specific report formats or named firms are contractually required
- Active litigation or IRS dispute where the study will be used as evidence and the preparer may need to testify
- One-of-a-kind construction where no comparable property exists in any database and physical inspection is the only way to identify components
When Traditional Pricing Is Not Justified
- Standard residential properties (SFR, duplex, small multi-family) — the engineering work is well-established and does not benefit from a $5,000+ fee
- Standard commercial properties (office, retail, apartments under 50 units) — component identification follows established patterns
- Properties where the firm charges based on value, not complexity — if the quote scales with your purchase price rather than building type and size, you are paying a valuation premium
- Any property where the study fee exceeds 15% of projected first-year savings — the ROI does not justify the cost at that ratio

The DIY and Desktop Study Problem
At the low end of the pricing spectrum, DIY software ($99–$500) and CPA desk studies ($1,500–$4,000) appear to offer cost segregation at a fraction of engineering-based pricing. The savings are real — but so are the risks.
Why DIY Studies Do Not Survive Audits
DIY cost segregation software applies generic allocation percentages to your purchase price. It does not identify specific components in your property. It does not apply engineering cost estimation. It does not classify assets based on your property's actual construction.
The IRS Cost Segregation Audit Techniques Guide instructs examiners to evaluate whether the study includes:
- Component-level detail with individual asset identification
- Cost estimates from recognized construction databases
- MACRS classifications supported by IRC §168 and relevant case law
- Qualifications of the preparer (engineering or construction expertise)
DIY software fails every one of these criteria. If audited, the IRS will compare the generic percentages in your DIY report to the actual components in your building — and the discrepancy will result in adjustment, potential penalties under IRC §6662 (negligence), and study costs that exceed what a professional study would have cost in the first place.
The CPA Desk Study Gray Area
CPA desk studies fall between DIY software and engineering-based studies. A competent CPA applying industry-average percentages can produce a reasonable planning estimate. But "reasonable planning estimate" and "IRS-defensible study" are different standards.
The key question: is there a named engineer on the report? If the answer is no, the study has lower defensibility under the IRS ATG regardless of the CPA's competence. For a deeper analysis of the DIY approach — including exactly what the engineering process involves and where self-prepared studies break down — see our complete DIY cost segregation guide. Modern CFO also offers a useful comparison of free calculator estimates vs. full engineering studies that helps investors understand where each tool fits.
Frequently Asked Questions
Q: How much does a cost segregation study cost for a rental property?
A: For a standard single-family rental, expect $1,440–$1,800 from an AI-native engineering provider (like Overline) or $2,500–$6,500 from a traditional engineering firm. Small multi-family (2–4 units) ranges from $1,800 (AI-native) to $3,000–$6,500 (traditional). Medium multi-family (5–20 units) ranges from $2,200 (AI-native) to $6,500–$12,000 (traditional). The fee should be evaluated against projected first-year tax savings — for most rental properties, cost segregation delivers 10x–50x+ ROI on the study cost. For savings estimates by property value, see how much does cost segregation save.
Q: Why do some firms charge $500 and others charge $15,000 for the same property?
A: The $500 study and the $15,000 study are not the same product. A $500 study is typically DIY software that applies generic percentages — no engineer, no property-specific analysis, no audit defensibility. A $15,000 study from a traditional firm includes on-site inspection, manual component identification, and engineering review — but also includes 40+ hours of manual labor that AI can perform in minutes, plus high overhead and profit margins. An AI-native engineering study ($1,440–$4,400) delivers the same engineering methodology and IRS defensibility as the $15,000 study at a fraction of the cost by automating the 80% of work that is pattern recognition.
Q: Is it worth paying more for an on-site inspection?
A: For standard residential and small commercial properties, an on-site inspection rarely changes the study outcome by more than 1–3 percentage points. The components in a typical SFR or apartment building are well-documented through property records, imagery, and owner-provided photos. For complex, specialized, or one-of-a-kind properties (hospitals, manufacturing, data centers), on-site inspection adds meaningful accuracy. At Overline, on-site inspections are available for $800+ when the property warrants it or the owner requests it — but they are not mandatory overhead applied to every study. See our site inspection photo guide for what inspections involve.
Q: What should I look for in a cost segregation engagement letter?
A: The engagement letter should specify: (1) the total fee, all-inclusive, with no hidden add-ons; (2) exactly what deliverables you will receive (depreciation schedules, component-level detail, Form 3115 if applicable); (3) the name and credentials of the engineer who will review the study; (4) audit defense terms (what support is included if the IRS questions your return); (5) turnaround time; and (6) the fee structure (flat fee, hourly, or percentage-based). If any of these are missing or vague, ask for clarification before signing. For the complete evaluation framework, see our provider checklist.
Q: Can I negotiate cost segregation study fees?
A: Yes. Most firms have flexibility, especially for multiple properties or repeat engagements. Ask for: (1) volume discounts if you have more than one property; (2) the flat-fee equivalent if the firm quotes hourly or percentage-based; (3) whether Form 3115 preparation is included or an add-on; (4) whether audit defense is included or extra. At Overline, volume discounts of 10% apply automatically for multi-property engagements, with additional discounts available upon request up to 20%.
Q: How does the One Big Beautiful Bill affect cost segregation study ROI?
A: The One Big Beautiful Bill Act (effective January 19, 2025) permanently restored 100% bonus depreciation for property acquired and placed in service after that date. This means the entire accelerated allocation identified in a cost segregation study can be deducted in the first year — dramatically increasing ROI. Before the restoration, bonus depreciation was phasing down (60% in 2024, 40% in 2025 under prior law). With 100% bonus permanent, a $750,000 SFR generating $53,300 in first-year savings at a $1,800 study cost delivers a 29.6x ROI. For the full legislative analysis, see our One Big Beautiful Bill bonus depreciation guide.
Q: What is the cheapest IRS-defensible cost segregation study available?
A: As of April 2026, the lowest-cost IRS-defensible engineering-based cost segregation study starts at $1,440 for a residential condo unit through Overline. For standalone single-family homes and small multi-family properties, the starting price is $1,800. These studies include licensed engineer review, component-level MACRS classifications, depreciation schedules, and audit defense. DIY software ($99–$500) is cheaper but is not engineering-based and is not considered defensible under the IRS ATG. For a full breakdown of affordable cost segregation options, see our dedicated guide.
Q: How do I know if my cost segregation quote is too high?
A: Compare the quote against the benchmarks in this article for your specific property type and provider type. If a traditional firm quotes $8,000 for a standalone SFR, that is within the observed range ($2,500–$6,500) but on the high end. If they quote $12,000 for the same property, that is above market. If an AI-native provider quotes $3,500 for an SFR, that is above the benchmark ($1,800) and should be questioned. The most reliable test: ask the firm how the fee was calculated. If the answer references your property value or projected savings rather than property type and complexity, you are likely paying a valuation premium.
Q: Should I get multiple cost segregation quotes?
A: Yes, especially for properties over $1M. Compare: (1) methodology — is it engineering-based or template-based? (2) pricing structure — flat fee, hourly, or percentage? (3) deliverables — what exactly do you receive? (4) audit defense — is it included? (5) turnaround time. Getting 2–3 quotes takes minimal effort and can save thousands. Use the benchmarks in this article to evaluate whether each quote is within the expected range for your property type.
Q: Do cost segregation study fees vary by state?
A: They should not — but they sometimes do. The engineering methodology for cost segregation is the same regardless of property location. A standalone SFR in Texas requires the same component identification and MACRS classification as one in California. Some traditional firms charge higher fees in high-cost-of-living markets (New York, San Francisco, Los Angeles), reflecting their local overhead rather than the engineering work required. AI-native providers typically maintain consistent national pricing because their cost structure is not tied to local real estate markets. For state-specific cost segregation information, see our cost segregation by state resource hub. Modern CFO also publishes a comprehensive cost segregation savings by state analysis covering how state taxes change your ROI.
Q: What is the typical turnaround time for a cost segregation study?
A: AI-native engineering providers typically deliver completed studies in 1–3 weeks (longer if an on-site inspection is included). Traditional engineering firms typically take 6–12 weeks due to scheduling, travel, and manual processing. CPA desk studies take 1–4 weeks. DIY software provides instant results. Turnaround time is a meaningful cost consideration beyond the study fee itself — delayed studies can push deductions into the next tax year, deferring the tax benefit.
The Bottom Line
The cost segregation industry has operated with opaque pricing for decades. Firms charge based on property value, projected savings, or billable hours — none of which reflect the actual engineering effort required to produce a defensible study.
This article provides the benchmark that has been missing: what studies actually cost to produce, what firms actually charge, and what investors should actually pay.
The data is clear:
- For standard residential properties, an IRS-defensible engineering-based study should cost $1,440–$2,200 from an AI-native provider. Traditional firms charging $5,000–$8,000 for the same work are pricing on perceived value, not production cost.
- For mid-size commercial properties, the range is $2,200–$4,400 (AI-native) versus $6,500–$18,000 (traditional). The engineering methodology is identical.
- For large or complex properties, AI-native pricing starts at $3,400–$5,400+ versus $12,000–$60,000+ traditional. At these property sizes, the absolute savings from choosing an efficient provider can exceed $10,000–$20,000 per study.
The question is not whether cost segregation is worth it — for most properties over $250,000, the ROI is overwhelming regardless of provider. The question is whether you are paying a fair price for the engineering work your property actually requires.
Matthew Gigantelli on the future of cost segregation pricing: "The firms that survive the next five years will be the ones that embrace technology and pass the efficiency gains to investors. The firms that continue charging $8,000 for 4 hours of engineering work wrapped in 40 hours of manual labor will lose to providers who deliver the same quality at a fraction of the cost. This is not a prediction — it is already happening."
