Cost Segregation Study for Rental Property Owners

Single-family rental properties contain significant depreciable components that most CPAs miss. Under the 2026 OBBBA, 100% of reclassified assets are deductible in year one — turning a standard deduction into a powerful first-year write-off.

Rental properties contain far more depreciable components than most owners realize.

Flooring, cabinetry, HVAC systems, electrical panels, landscaping, driveways, fencing — these are reclassified from the 27.5-year default to 5 or 15-year recovery periods. In a typical single-family rental, 22–28% of the purchase price qualifies for acceleration.

Most rental property owners don't realize they're leaving $25,000–$55,000+ in first-year deductions on the table by letting their CPA depreciate everything over 27.5 years.

The $25,000 rental loss allowance — and how cost seg maximizes it.

For rental property owners with AGI under $150,000, the IRS allows up to $25,000 in rental losses to offset active income each year. A cost segregation study creates large first-year depreciation deductions that maximize this allowance — and for those above the AGI threshold, the excess carries forward.

IRC Section 469(i) — The $25,000 Rental Loss Allowance
26 U.S.C. § 469(i) · Active participation in rental real estate

Individuals who actively participate in rental real estate activities may deduct up to $25,000 of rental losses against non-passive income. This allowance phases out between $100,000 and $150,000 AGI.

Even if your AGI exceeds $150,000, the accelerated depreciation creates passive losses that offset rental income and carry forward to future years — or to the year you sell. For real estate professionals who qualify under IRC §469(c)(7), there are no passive loss limits at all.

Typical asset breakdown for a single-family rental

We analyze every component of your property. Here's what a typical rental property study identifies:

Asset CategoryRecovery PeriodExamples% of Basis
Personal Property5 yearsFlooring, cabinetry, appliances, electrical, plumbing fixtures, carpet15–20%
Land Improvements15 yearsLandscaping, driveway, sidewalks, fencing, outdoor lighting, retaining walls7–10%
Building Components27.5 yearsStructural framing, foundation, roof, exterior walls55–70%
LandNon-depreciableLot value15–25%

On a $800K single-family rental, that typically means $130K–$200K in accelerated deductions available in year one.

Material Participation & Real Estate Professional Status

How you use your depreciation losses depends on your participation level and how the property is rented. Under IRC §469 (unchanged by OBBBA), there are three paths to using cost segregation losses against your active income:

Path 1: Short-Term Rental Loophole (No REPS Required)
IRC §469(j)(8) · Treas. Reg. §1.469-1T(e)(3)(ii)(A)

If your average guest stay is 7 days or fewer (Airbnb, VRBO, vacation rental), the activity is not treated as a rental activity. Losses can offset W-2 and business income — provided you materially participate. No REPS qualification needed.

Path 2: Real Estate Professional Status (REPS)
IRC §469(c)(7) · 750-hour test + 50% test

For long-term rentals, qualify as a Real Estate Professional to treat rental losses as non-passive. You must: (1) spend more than 750 hours per year in real property trades or businesses, and (2) that time must represent more than 50% of your total working hours. One spouse can qualify for a joint return.

Path 3: $25,000 Rental Loss Allowance
IRC §469(i) · Active participation

If you actively participate in your rental (make management decisions, approve tenants, authorize repairs) and your AGI is under $150,000, you can deduct up to $25,000 in rental losses against active income. Phases out between $100K–$150K AGI. Excess losses carry forward.

What changed in 2026: The OBBBA permanently restored 100% bonus depreciation under IRC §168(k) for qualified property acquired after January 19, 2025. This means a cost segregation study now creates larger first-year paper losses than ever — making the path you use to deduct those losses more important than ever. The passive activity rules under §469 remain unchanged.

Bottom line: If you qualify through any of these three paths, a cost segregation study combined with 100% bonus depreciation can produce $30,000–$150,000+ in first-year tax savings on a single property. We'll confirm your eligibility on a free 15-minute call before you commit to anything.
