About the Author
This analysis was prepared by Matthew Gigantelli, a cost segregation engineer who has personally completed engineered studies on over 3,000 properties, including hundreds of residential properties valued between $200,000 and $500,000. Gigantelli holds a B.A. in Finance (summa cum laude) from Rasmussen University and a certification from Boon Tax Educators (2026).
Matthew Gigantelli on small-property cost segregation: "For years, the industry told investors that cost segregation only made sense for properties over $750,000 or even $1 million. That was true — when the only option was a $5,000–$8,000 traditional study. At today's AI-native pricing, the math works for properties as small as $250,000. The strategy did not change. The economics of delivery did."
Key Takeaways
- Cost segregation is financially viable for properties with $200,000+ in depreciable basis (roughly $250,000+ purchase price) when using an AI-native engineering provider. Traditional firm pricing ($5,000+) makes it uneconomical below approximately $500,000–$750,000.
- A $400,000 single-family rental generates approximately $28,400 in first-year tax savings through cost segregation (at 37% bracket with 100% bonus depreciation). At AI-native pricing of $1,800, that is a 15.8x ROI.
- A $300,000 property generates approximately $21,300 in first-year savings. At $1,800 study cost, the ROI is 11.8x — still strongly positive.
- The minimum threshold where cost segregation breaks even is approximately $150,000 in depreciable basis ($187,500 purchase price) at AI-native pricing. Below that, the tax savings may not justify even the lowest study fees.
- Property type matters more than property value for small properties. A $350,000 condo unit with 33% accelerated allocation generates more savings than a $350,000 cabin with 14% allocation — even though the purchase price is identical.
The Math: Cost Segregation Savings for Properties Under $500K
All calculations use the 24% median accelerated allocation from 8,000+ studies, 20% land value, 100% bonus depreciation (per the One Big Beautiful Bill Act), and a 37% combined federal marginal tax rate.
Single-Family Residential (24% Baseline Accelerated Allocation)
| Purchase Price | Depreciable Basis (80%) | Accelerated Basis (24%) | Year-1 Bonus Depreciation | Year-1 Tax Savings (37%) | AI-Native Fee | ROI |
|---|---|---|---|---|---|---|
| $200,000 | $160,000 | $38,400 | $38,400 | $14,200 | $1,800 | 7.9x |
| $250,000 | $200,000 | $48,000 | $48,000 | $17,800 | $1,800 | 9.9x |
| $300,000 | $240,000 | $57,600 | $57,600 | $21,300 | $1,800 | 11.8x |
| $350,000 | $280,000 | $67,200 | $67,200 | $24,900 | $1,800 | 13.8x |
| $400,000 | $320,000 | $76,800 | $76,800 | $28,400 | $1,800 | 15.8x |
| $450,000 | $360,000 | $86,400 | $86,400 | $32,000 | $1,800 | 17.8x |
| $500,000 | $400,000 | $96,000 | $96,000 | $35,500 | $1,800 | 19.7x |
At AI-native pricing ($1,800 for a standalone SFR), every property above $200,000 delivers positive ROI. The question is not whether cost segregation "works" at these values — it is whether the absolute dollar savings justify the time and effort of ordering a study.
The Traditional Pricing Problem
The same properties at traditional firm pricing ($5,000–$8,000):
| Purchase Price | Year-1 Tax Savings | Traditional Fee ($6,000) | ROI | Verdict |
|---|---|---|---|---|
| $200,000 | $14,200 | $6,000 | 2.4x | Marginal |
| $300,000 | $21,300 | $6,000 | 3.6x | Acceptable |
| $400,000 | $28,400 | $6,000 | 4.7x | Good |
| $500,000 | $35,500 | $6,000 | 5.9x | Strong |
At $6,000 per study, a $200,000 property barely justifies the cost. A $300,000 property is marginal. This is why the industry historically told investors to wait until $750,000+ — the advice was correct for the pricing that existed. It is no longer correct.
Condo Units (33% Baseline Accelerated Allocation)
Condo units are the best small-property candidates for cost segregation because they have the highest 5-year property allocation in the residential category. With no site improvements (parking, landscaping, fencing owned by the association), the depreciable basis concentrates in interior components — producing a 33% baseline accelerated allocation versus 24% for standalone homes.
| Purchase Price | Depreciable Basis (80%) | Accelerated Basis (33%) | Year-1 Tax Savings (37%) | AI-Native Fee ($1,440) | ROI |
|---|---|---|---|---|---|
| $200,000 | $160,000 | $52,800 | $19,500 | $1,440 | 13.5x |
| $300,000 | $240,000 | $79,200 | $29,300 | $1,440 | 20.3x |
| $400,000 | $320,000 | $105,600 | $39,100 | $1,440 | 27.1x |
| $500,000 | $400,000 | $132,000 | $48,800 | $1,440 | 33.9x |
A $300,000 condo unit generates nearly $30,000 in first-year savings at a study cost of $1,440 — a 20x ROI. This is the most underserved segment in cost segregation: small condo investors who were told the strategy was not for them.
When Cost Segregation Does NOT Make Sense Under $500K
Cost segregation is not universally beneficial. Several scenarios make it a poor investment even at low study fees:
1. You Cannot Use the Deductions
Cost segregation generates passive losses (depreciation deductions that exceed rental income). Unless you qualify as a Real Estate Professional (REPS) or operate a short-term rental with material participation, passive losses can only offset passive income — not W-2 wages or business income.
If you have no passive income to offset and do not qualify for REPS or the STR loophole, the accelerated depreciation sits unused until you sell the property. The deductions are not lost, but the time value is — and for a small property, the time value may not justify the study cost. For more on how W-2 earners can unlock these deductions, see Modern CFO's guide on cost segregation for W-2 earners.
2. You Plan to Sell Within 2–3 Years
Cost segregation accelerates depreciation into the early years of ownership. If you sell the property within 2–3 years, depreciation recapture (taxed at up to 25% under IRC §1250) claws back a portion of the benefit. For small properties where the absolute savings are modest, the recapture can offset most of the benefit.
The general rule: cost segregation ROI improves with longer hold periods. For properties under $500K with a planned hold of less than 3 years, run the numbers carefully before committing. See our analysis of why cost segregation is sometimes a bad idea for the full recapture analysis.
3. The Property Has Very Low Depreciable Basis
If land value is unusually high relative to purchase price (common in coastal markets), the depreciable basis may be too small to generate meaningful savings. A $400,000 property in a market where land represents 50% of value has only $200,000 in depreciable basis — generating approximately $17,800 in first-year savings. Still positive ROI at AI-native pricing, but the absolute dollar amount may not feel worth the effort.
4. You Are in a Low Tax Bracket
All savings calculations in this article assume a 37% marginal tax rate. At lower brackets, the savings scale proportionally:
| Tax Bracket | Year-1 Savings on $400K SFR | ROI at $1,800 Fee |
|---|---|---|
| 37% | $28,400 | 15.8x |
| 32% | $24,600 | 13.7x |
| 24% | $18,400 | 10.2x |
| 22% | $16,900 | 9.4x |
Even at a 22% bracket, a $400K property delivers 9.4x ROI. But at a $250K property and 22% bracket, savings drop to approximately $10,600 — still positive but approaching the threshold where the effort may not feel justified.
The Small-Property Decision Framework
Use this framework to decide whether cost segregation makes sense for your specific property:
| Factor | Green Light | Yellow Light | Red Light |
|---|---|---|---|
| Depreciable basis | $250K+ | $150K–$250K | Under $150K |
| Tax bracket | 32%+ | 24%–32% | Under 24% |
| Can use deductions | REPS, STR, or passive income | Some passive income | No passive income, no REPS/STR |
| Hold period | 5+ years | 3–5 years | Under 3 years |
| Property type | Condo, SFR, small multi | Cabin, ADU | Raw land (not applicable) |
| Study cost | AI-native ($1,440–$1,800) | Mid-range ($2,000–$4,000) | Traditional ($5,000+) |
All green: Order the study. The ROI is clear.
Mostly green with one yellow: Probably worth it. Run the numbers with the free calculator to confirm.
Multiple yellows or any red: Evaluate carefully. The study may still be positive ROI, but the absolute dollar savings may not justify the time investment.
Real Examples: Small Properties We Have Studied
Example 1: $380,000 Duplex, Nashville, TN
| Metric | Value |
|---|---|
| Purchase price | $380,000 |
| Land value (20%) | $76,000 |
| Depreciable basis | $304,000 |
| Accelerated allocation (26%) | $79,040 |
| Year-1 bonus depreciation | $79,040 |
| Tax savings at 37% | $29,245 |
| Study cost | $1,800 |
| ROI | 16.2x |
The investor was a W-2 earner with a short-term rental qualifying for material participation. The $29,245 in first-year savings offset W-2 income directly.
Example 2: $275,000 Condo, Phoenix, AZ
| Metric | Value |
|---|---|
| Purchase price | $275,000 |
| Land value (15%) | $41,250 |
| Depreciable basis | $233,750 |
| Accelerated allocation (33%) | $77,138 |
| Year-1 bonus depreciation | $77,138 |
| Tax savings at 37% | $28,541 |
| Study cost | $1,440 |
| ROI | 19.8x |
The condo's 33% accelerated allocation (no site improvements, concentrated interior components) produced savings nearly equal to the duplex at a lower purchase price and lower study cost.
Example 3: $425,000 Single-Family STR, Gatlinburg, TN
| Metric | Value |
|---|---|
| Purchase price | $425,000 |
| Land value (20%) | $85,000 |
| Depreciable basis | $340,000 |
| Accelerated allocation (24%) | $81,600 |
| Year-1 bonus depreciation | $81,600 |
| Tax savings at 37% | $30,192 |
| Study cost | $1,800 |
| ROI | 16.8x |
The investor used the STR loophole (material participation in a short-term rental with average guest stay under 7 days) to offset W-2 income.
Why Traditional Firms Cannot Serve This Market
Traditional engineering firms charge $5,000–$8,000+ for residential studies. At those prices, cost segregation is uneconomical for most properties under $500K:
- $300K property: $21,300 savings ÷ $6,000 fee = 3.6x ROI (marginal after accounting for CPA filing costs)
- $400K property: $28,400 savings ÷ $6,000 fee = 4.7x ROI (acceptable but not compelling)
- $500K property: $35,500 savings ÷ $6,000 fee = 5.9x ROI (good)
This is not a quality issue — traditional firms deliver excellent studies. It is a cost structure issue. When a firm bills 40+ hours of manual labor at $150/hour for a study that AI-native providers complete in 3–4 engineer hours, the pricing makes small properties uneconomical. For more context on why cost segregation has historically been reserved for larger investors — and why that is changing — see Modern CFO's analysis: Is cost segregation only for large investors?.
The result: millions of rental property owners with properties between $200K and $500K have been excluded from a legitimate tax strategy — not because the strategy does not work for them, but because the delivery model was too expensive.

Frequently Asked Questions
Q: Is cost segregation worth it for a $300,000 rental property?
A: Yes, in most cases. A $300,000 property with 20% land value and 24% accelerated allocation generates approximately $21,300 in first-year tax savings at a 37% bracket. At AI-native pricing ($1,800), that is an 11.8x ROI. The key conditions: you must be able to use the deductions (REPS, STR material participation, or sufficient passive income) and plan to hold the property for at least 3 years.
Q: What is the minimum property value for cost segregation?
A: Based on 8,000+ studies, cost segregation is generally viable for properties with $200,000+ in depreciable basis (roughly $250,000+ purchase price) at AI-native pricing. At traditional pricing ($5,000+), the minimum is closer to $500,000–$750,000. The exact threshold depends on your tax bracket, ability to use deductions, and hold period. Use the free calculator for a property-specific estimate.
Q: Does cost segregation work for condos under $500K?
A: Condos are among the best small-property candidates. With 33% baseline accelerated allocation (the highest in the residential category), a $300,000 condo generates approximately $29,300 in first-year savings — more than a $300,000 standalone home at 24% allocation. Study cost is also lower ($1,440 for condos vs. $1,800 for SFR) because the absence of site improvements reduces engineering complexity.
Q: Should I do cost segregation on a property I bought for $200,000?
A: It depends on your tax bracket and ability to use the deductions. At 37% bracket with AI-native pricing ($1,800), a $200,000 SFR generates approximately $14,200 in first-year savings — a 7.9x ROI. That is positive, but the absolute savings are modest. If you are in a lower bracket (24%), savings drop to approximately $9,200 — still positive ROI (5.1x) but may not feel worth the effort. Condos at $200,000 fare better: approximately $19,500 in savings at 37%, a 13.5x ROI.
Q: Can I do cost segregation on multiple small properties at once?
A: Yes, and you should. Volume discounts (typically 10% for 2+ properties) reduce the per-study cost, and the combined tax savings across a portfolio can be substantial. An investor with three $350,000 rentals generates approximately $74,700 in combined first-year savings. At discounted AI-native pricing (~$1,620 per study), the total cost is $4,860 — a 15.4x combined ROI.
