Is Cost Segregation Worth It for a Short-Term Rental?

The honest answer: for most short-term rentals above $400,000, yes. For properties below that threshold, it depends on your tax situation.

Here's how to think about it.

What cost segregation actually does

Standard depreciation spreads your property's cost over 27.5 years. Cost segregation reclassifies specific components — flooring, appliances, outdoor features, specialty systems — into shorter depreciation schedules: 5 years or 15 years instead of 27.5. That front-loads your deductions dramatically.

On a $700,000 STR with a $560,000 depreciable basis, standard depreciation gives you roughly $20,000 in deductions per year. Cost segregation, with bonus depreciation, can deliver $40,000–$65,000 in year one alone.

The break-even calculation

A quality cost segregation study runs $800–$2,500 depending on the provider and property type. At Segmint, a full certified study is $1,197.

The question is simple: does the tax saving from the accelerated deductions exceed the study cost?

At a 24% federal tax bracket, $50,000 in additional first-year deductions saves you $12,000 in federal taxes. The study costs $1,197. That's a 10x return in year one.

The break-even threshold at a 22% bracket:

Rule of thumb: if your purchase price is above $400,000 and you acquired the property in 2025 or later, run the numbers. The study almost certainly pays for itself.

The REPS caveat

There's one thing that changes this calculation: Real Estate Professional Status. If you don't qualify as a real estate professional, your cost segregation deductions are classified as passive losses. That means they can only offset passive rental income — not your W-2 or business income.

If your STR generates strong rental income, this isn't a problem. If it's your only rental property and it breaks even on cash flow, the deductions may carry forward unused until you have more passive income or sell the property.

This doesn't make cost segregation worthless for non-REPS taxpayers — it just changes the timing of the benefit. Know your passive income position before you pull the trigger.

STRs specifically

Short-term rentals tend to be better cost segregation candidates than long-term rentals for one reason: amenities. A property with a hot tub, outdoor kitchen, EV charger, game room, or smart home system has more reclassifiable components. Each of those is a 5-year or 15-year asset rather than a 27.5-year structural component.

The more amenities, the bigger the reclassification. An Airbnb with a pool and outdoor kitchen will outperform a bare-bones long-term rental of the same price.

The bottom line

Cost segregation is worth it for most STRs above $400,000, especially those acquired in 2025 or later when bonus depreciation is available. The study cost is a rounding error relative to the tax benefit.
