Testimonials

Real Owners, Real Savings

What investors say about keeping more of what they earn.

"Overline's cost segregation study unlocked $140K in bonus depreciation on my $600K rental property. As a W-2 earner making $350K, I offset nearly 40% of my tax burden in year one. The property cash flows beautifully on top of that."

David Chen

Software Engineer, Google

"I bought a 4-unit building and Overline's cost segregation analysis found $85K in accelerated depreciation I could take immediately. That's $31K in tax savings year one while building long-term wealth. Game changer."

Sarah Miller

Product Manager, Stripe

"The short-term rental loophole combined with cost segregation is incredible. My Airbnb generates $7K/month and I got $95K in bonus depreciation write-offs. All my W-2 income from Microsoft is now essentially tax-free."

Michael Torres

Principal Engineer, Microsoft

"Cost segregation on my rental property gave me $120K in first-year deductions. Combined with the property's cash flow, my after-tax returns are 22%. Overline's analysis was thorough and IRS-defensible."

Jennifer Park

Director of Finance, Meta

"Between my Amazon salary and RSU vesting, I needed serious tax relief. Bought a rental property and Overline's cost seg study found $160K in accelerated depreciation. Saved $59K in taxes immediately."

Robert Kim

Engineering Manager, Amazon

"Overline showed me how to use bonus depreciation on rental properties to offset my high W-2 income. My duplex investment gave me $75K in write-offs year one. Now my $250K salary is barely taxed."

Amanda Watson

VP of Product, Tech Startup

"The cost segregation study paid for itself 10x over. Found $200K in accelerated depreciation on my commercial property. That's $74K in immediate tax savings while the property generates consistent income."

James Rodriguez

Real Estate Developer

"As a high-income physician, I never knew rental properties could offset my taxes so aggressively. Overline's cost seg analysis found $110K in bonus depreciation. Best investment decision I've made."

Dr. Emily Martinez

Surgeon, Private Practice

"Bought my first rental property through Overline. The cost segregation study accelerated $90K in depreciation, saving me $33K in taxes year one. The property also cash flows $1,200/month. Perfect combination."

Thomas Lee

Investment Banker, Goldman Sachs

"My Netflix salary puts me in the highest tax bracket. Cost segregation on two rental properties gave me $240K in write-offs. Now I'm building wealth while dramatically reducing my tax bill. Incredible."

Lisa Anderson

Senior Engineer, Netflix

FAQ

Common Questions

Everything you need to know about how Overline works.

  • What is Overline and how does it help rental property owners?

    Overline is an AI agent built for real estate owners. It runs continuously in the background — handling tax optimization (cost segregation, depreciation, REPS hour tracking), insurance benchmarking, financing optimization (rate monitoring, refinance opportunities), and liability compliance — so you stop leaving money on the table across the three biggest silent cash flow killers in real estate. Instead of piecing together CPAs, insurance brokers, lenders, and attorneys yourself, Overline handles the coordination automatically.

  • Most investors only claim depreciation when they buy a property. Your agent finds deductions upfront through cost segregation, plus ongoing savings every time you renovate, replace appliances, or improve the property. It connects to QuickBooks to automatically identify deductible expenses you might overlook — and every study it produces is verified by a licensed engineer and CPA before going to your return.

  • Cost segregation is an IRS-approved strategy that accelerates depreciation by reclassifying parts of your property (flooring, fixtures, landscaping, etc.) into shorter depreciation schedules — 5, 7, or 15 years instead of 27.5 years. This front-loads your tax deductions, often generating $15,000–$50,000+ in year-one savings on a typical rental. Overline estimates your potential benefit for free, so you know if it's worth it before committing to a full study — and every study we produce is verified and stamped by a licensed engineer and CPA, so the numbers are IRS-defensible and CPA-ready. See actual savings by property type or use our decision framework to evaluate your ROI.

  • Insurance premiums creep up every year while coverage gaps put you at risk. Your AI agent benchmarks your rates against a carrier network to catch overcharges, and uses your cost segregation asset inventory to document property values — which speeds up claims and helps maximize payouts if something goes wrong. Your tax analysis doubles as insurance protection.

  • Without proper legal structure, one tenant lawsuit could threaten your home, savings, and personal assets. An LLC creates a liability shield — if something happens at your rental property, creditors can only pursue the LLC's assets, not your personal wealth. Overline helps you set up LLCs and trusts the right way, keeping each property's risk separate from you and from each other.

  • Your CPA files your taxes based on what you give them. Your AI agent proactively finds savings they'd otherwise miss — cost segregation studies, renovation write-offs, REPS hour logs, and insurance benchmarks. Critically, every cost segregation study your agent produces is verified and signed off by a licensed engineer and CPA before it touches your return, so it's IRS-defensible, not just a software estimate. Overline doesn't replace your CPA — it does the heavy lifting and hands them documentation they can use directly.

  • Overline is built for working professionals — W-2 earners, business owners, high-income earners — who own rental properties and are tired of overpaying on taxes, insurance, and financing. Whether it's your first rental or your tenth, your agent brings institutional-grade optimization across all three to individual investors automatically.

  • Start by joining our waitlist — we'll invite you to connect your properties and run a free analysis to show your potential savings. From there, you can access our tax optimization tools, insurance benchmarking, financing rate analysis, and LLC setup services.
