Cost Segregation for Mountain Cabins: STR Tax Deductions for Cabin Owners
Mountain cabins are among the most profitable short-term rental property types — and among the most favorable for cost segregation. The typical cabin purchase includes a significant allocation to specialty items: custom log work, stone fireplaces, hot tubs, game rooms, theater setups, and outdoor entertainment areas. Each of these reclassifies under cost segregation from 39-year real property to 5-year or 7-year personal property, making them immediately bonus-depreciable.
Why Mountain Cabins Have an Excellent Depreciation Profile
In a standard residential property, roughly 20–25% of the depreciable basis can be reclassified. Mountain cabins routinely exceed this, with 28–38% reclassification rates common in detailed studies. The driver is the high density of personal property — furnishings, entertainment equipment, hot tubs, outdoor fire pits — relative to the total property value.

| Game room equipment (pool table, arcade) | 5-year personal property | 5 years | Yes |
| Home theater system | 5-year personal property | 5 years | Yes |

| Outdoor fire pit | 15-year land improvement | 15 years | Yes |
| Deck / wraparound porch | 15-year land improvement | 15 years | Yes |
| Gravel driveway / parking | 15-year land improvement | 15 years | Yes |
| Outdoor lighting | 15-year land improvement | 15 years | Yes |
| Log siding (if decorative) | Potentially 5-year | 5 years | Case-by-case |
Top Cabin Markets and What to Expect
Gatlinburg/Pigeon Forge, Breckenridge/Keystone, Asheville/Blue Ridge, Big Bear, Lake Tahoe, and Park City are the highest-volume cabin STR markets. Purchase prices typically range $400K–$1.2M, making cost segregation highly cost-effective (study fees of $1,500–$5,000 against deductions of $60K–$200K+).
The STR Loophole and Cabin Rentals
Mountain cabins rented on a weekly basis (average stay 7 days or less) qualify for the STR tax loophole. This means depreciation losses from your cost segregation study are not limited to passive activity rules — they offset ordinary income directly. For a cabin owner earning $300K–$600K in salary, a $100K depreciation deduction from a cabin cost seg study can translate to $37K–$44K in tax savings in a single year.
2025 Update: 100% Bonus Depreciation Reinstated
The One Big Beautiful Budget Act (OBBBA), signed July 4, 2025, reinstated 100% bonus depreciation for qualifying property acquired after January 19, 2025. Cabin owners who purchased properties in 2025 or later can deduct the full value of all reclassified 5-, 7-, and 15-year property in year one. This dramatically increases the immediate cash benefit of a cost segregation study.
