Cost segregation on a $1.5M Airbnb / Short-Term Rental reclassifies $360,000 into accelerated depreciation.
Engineering-based study using industry-standard 2026 construction cost data and IRS Audit Techniques Guide methodology. Numbers below are computed from the same formula our production studies use — adjust for your actual property with the calculator at the bottom.
How the $360,000 splits across 5-, 7-, and 15-year property.
These percentages are illustrative for a airbnb / short-term rental of this size and age. Your study reports component-level detail so your CPA can place each item on the correct depreciation schedule.
5-year property
Personal property: appliances, carpet, FF&E, decorative finishes. Fully bonus-eligible at 100% under OBBBA (2025+).
7-year property
Office furniture, certain equipment, specialty fixtures. Also bonus-eligible.
15-year property
Land improvements: driveways, fencing, landscaping, site lighting. Bonus-eligible.
Without a study vs. with one.
At a 37% federal bracket, that's $133,200 in cash you keep instead of paying — a 84× return on the $1,595 study. Run it on your actual property below.
The $1.5M airbnb / short-term rental at four federal brackets.
The headline figure assumes the top 37% bracket. Most owners are not in it, so here is the same $360,000 Year-1 deduction valued at other federal rates, before and after the $1,595 study fee. State income tax comes on top where your state conforms to federal bonus depreciation.
| Federal bracket | Year-1 tax value | After the $1,595 fee |
|---|---|---|
| 24% | $86,400 | $84,805 |
| 32% | $115,200 | $113,605 |
| 35% | $126,000 | $124,405 |
| 37% | $133,200 | $131,605 |
A $1.5M purchase price falls in the $1.5M–$2M band of our Single-family / STR / Condo / ADU pricing, a flat $1,595. At $2,000,000 and above the next band applies ($1,995). See the full pricing table.
Depreciation on a $1,200,000 basis, with and without the study.
The Year-1 reclassification of $360,000 equals about 8.3 years of standard 27.5-year depreciation on this property. After Year 1 the study's annual deduction is smaller, because the reclassified $360,000 has already been taken and only the $840,000 remaining building basis is still depreciating. Full years shown; the purchase year is shorter under the mid-month convention.
| Year | No study | With study | Cumulative extra deduction |
|---|---|---|---|
| Year 1 | $43,636 | $390,545 | $346,909 |
| Year 2 | $43,636 | $30,545 | $333,818 |
| Year 3 | $43,636 | $30,545 | $320,727 |
| Year 4 | $43,636 | $30,545 | $307,636 |
| Year 5 | $43,636 | $30,545 | $294,545 |
The cumulative gap narrows by $13,091 a year and closes over the recovery period; cost segregation changes when you deduct, not how much. Depreciation taken is generally recaptured on a taxable sale.
