Smoky Mountain Cost Segregation Calculator
Estimate how much depreciation a cost segregation study could accelerate into year one on your Gatlinburg, Pigeon Forge, or Sevierville short-term rental — and what that could mean for your tax bill. A directional planning tool, not a substitute for a study or your CPA's advice.
If you own — or are about to buy — a short-term rental in the Smoky Mountains, cost segregation is one of the most powerful tax strategies available to you. Instead of depreciating your cabin evenly over 27.5 or 39 years, an engineering-based study reclassifies furniture, fixtures, decks, driveways, hot tubs, and landscaping into 5- and 15-year categories that can be deducted far faster. Under the 100% bonus depreciation restored by the One Big Beautiful Bill Act, much of that accelerated basis can be written off in year one.
For investors in Gatlinburg, Pigeon Forge, and Sevierville, the math is especially favorable: Tennessee has no state income tax, Sevier County carries one of the lowest effective property tax rates in the country, and furnished cabins carry an unusually high share of fast-depreciating components. Pair that with the short-term rental "loophole" — where material participation can let those paper losses offset W-2 and business income — and a single study can reshape your return.
This free calculator gives you a directional estimate of your year-one savings before you commission a study. Enter your property details below for an instant, property-type-specific report. It's built by Brandon Williams of SCALE with LPT Realty, a Smoky Mountain short-term rental and investment consultant — not a CPA. Treat the numbers as a starting point for a conversation with your tax advisor, not as tax advice.

Depreciation Recapture — If You Sell
Accelerating depreciation isn't free money — it lowers your basis, so more gain is taxed when you sell. Here's the rough trade-off to discuss with your CPA.

This is a planning tool, not tax advice — and we are not CPAs. SCALE with LPT Realty is a real estate brokerage and consultancy. We are not a CPA firm, accounting firm, or tax advisor, and nothing here is tax, legal, or accounting advice.
No guarantee of results. Every figure is a directional estimate built on industry benchmark ranges and simplifying assumptions. Your actual reclassification percentages, deductible amounts, and tax savings will differ and can only be determined by a qualified engineering-based cost segregation study and your own tax professional.
Following up with your CPA is strongly recommended and advised. Whether a study makes sense — and whether you can actually use the deductions — depends on passive activity rules, at-risk and basis limits, material participation, excess business loss rules, state conformity, and your full tax picture. Please review any decision with your CPA or tax advisor before acting.
This tool simply helps provide direction. It does not create a client relationship and should not be the sole basis for any purchase, sale, or tax decision.
