If you own an investment property, you need a cost segregation study. TDA delivers IRS-compliant, engineering-based studies that accelerate your depreciation, unlock 100% OBBBA bonus depreciation, and put more cash back in your pocket in year one.
No commitment. We model the exact deductions before you spend a dollar.
From our free feasibility to a completed report - we handle the engineering so your CPA can claim you the maximum savings.
Send us the address and purchase price. We deliver a free feasibility report shortly, showing projected first-year deductions and ROI.

Talk to a specialist →The One Big Beautiful Bill Act restored 100% bonus depreciation for qualifying property acquired and placed in service after January 19, 2025. That means every dollar of 5-, 7-, and 15-year property identified in a cost segregation study can be deducted in year one — instead of dragging out over 27.5 or 39 years.
For a $2 million commercial building, that often translates to $300,000–$600,000 of accelerated first-year deductions, depending on building type and structure.
Engineering-based cost segregation isn't a spreadsheet. It's a defensible study built on construction documents and current IRS guidance.
Send us the property address, purchase price, and date placed in service. We model expected reclassification and projected first-year deduction at no cost.
We collect closing documents, depreciation schedule, construction drawings, and any TI/CapEx history.
Our team itemizes building components, applies MACRS class lives per IRS audit guidance, and quantifies costs using accepted estimating standards.
You receive a report ready for your CPA to use in your tax return.
TDA is a depreciation-only firm. We don't sell software, audits, or tax prep — we do one thing, the right way, with engineering rigor and tax-code precision.
Real outcomes across asset classes — numbers shown are typical mid-range results for OBBBA-era studies.
A 96-unit garden-style multifamily in Texas. Site-improvement-heavy lot drove an above-average reclassification. Owner saved ~$252K federal tax in year one at a 37% bracket.
An Airbnb in the Smokies with extensive deck, hot tub, and decorative finishes. STR strategy let the owner offset W-2 income directly — ~$44K of cash tax saved.
Suburban Class A office with structured parking, dedicated electrical, and high-end TI buildouts.
A 110-key hotel in Florida. FF&E plus decorative finishes drove one of our highest reclassification ratios — ~$777K cash tax saved.
Tilt-up industrial in the Inland Empire. Heavy paving, racking, and dedicated process electrical. Lower % reclassification but very high absolute dollars.
A 22,000 sq ft medical office. Specialty plumbing, dedicated electrical, and lab/imaging buildouts created one of the richest reclassification profiles we see.
From single-property landlords to multi-state syndicators — we deliver studies that hold up to IRS scrutiny and put real cash back in their pockets.

A cost segregation study is an engineering-based analysis that reclassifies components of a building from 39-year (commercial) or 27.5-year (residential rental) real property into 5-, 7-, and 15-year MACRS class lives. The reclassification accelerates depreciation deductions, reducing current-year federal taxable income for property owners.
Typical commercial properties reclassify 20–35% of cost basis into shorter recovery periods. Combined with 100% bonus depreciation under OBBBA, that produces first-year deductions in the range of 6–12% of purchase price. Net present value of the tax savings commonly ranges from 5% to 12% of acquisition cost depending on building type and your tax bracket.
Yes. The One Big Beautiful Bill Act restored 100% bonus depreciation on qualifying property acquired and placed in service after January 19, 2025. Cost segregation is the mechanism that identifies which components of a building qualify, making it more valuable than at any time since 2022.
Residential studies are delivered in 5–7 days and commercial studies in 10 days from engagement. Rush turnaround is available for year-end or transaction deadlines.
