Residential rental property owners can accelerate depreciation and unlock tens of thousands in tax savings through a properly executed cost segregation study.
If you own residential rental property, the IRS requires you to depreciate the building over 27.5 years. But a significant portion of that property — often 20% to 40% of the total cost basis — can be reclassified into shorter-lived asset categories. That's the power of a cost segregation study.
A cost segregation study is an engineering-based analysis that identifies building components eligible for accelerated depreciation. Instead of depreciating everything over 27.5 years, certain elements get reclassified into 5-year, 7-year, or 15-year categories.
For a residential rental property, reclassifiable components typically include:
Cost segregation delivers the greatest impact for residential rental property owners who:
Example: A $1.2M residential rental property might yield $250,000–$400,000 in reclassified assets. With bonus depreciation, that translates to $60,000–$100,000+ in first-year tax savings — depending on your bracket and filing status.
Yes. The IRS allows a "look-back" cost segregation study on properties you already own. Through a change in accounting method (Form 3115), you can claim the cumulative catch-up depreciation in a single tax year — no need to amend prior returns.
This is one of the most overlooked opportunities in cost segregation. Many property owners assume they missed the window, but you can still capture significant deductions on properties acquired years ago.
Under current tax law, bonus depreciation allows you to take 100% of the reclassified depreciation in year one for assets placed in service before 2023. The rate phases down 20% per year after that — so acting sooner captures more savings. Read our full breakdown of cost segregation vs. bonus depreciation.
For a typical residential rental property, a cost segregation study costs $5,000–$15,000 depending on the property size and complexity. Given that most studies identify $50,000–$200,000+ in accelerated deductions, the ROI is substantial. See our detailed breakdown of cost segregation study pricing.
