TL;DR
No, you do not have to buy a new short-term rental every year. Year one delivers the largest deduction because cost segregation and 100% bonus depreciation front-load it. After that you still get ongoing depreciation, you can carry unused losses forward, and you can generate new deductions through improvements. Buying yearly is only necessary if you want to keep wiping out a high income every year.
Why is year one the big deduction?
Because cost segregation plus 100% bonus depreciation pulls years of deductions into the first year. A cost seg study reclassifies 25% to 35% of your building into 5-, 7-, and 15-year property, and bonus depreciation (restored to 100% by the OBBBA for property acquired after January 19, 2025) deducts all of it at once. That is the spike that can take a W-2 earner's taxable income to zero. See our guide on cost segregation and the STR loophole for the full mechanics.
After year one, the front-loaded components are already deducted, so the property produces smaller, ordinary depreciation in later years. That does not mean the benefit stops. It means the shape changes from one big year to a steady tail, plus whatever you choose to add.
Do I lose the benefit in year two and beyond?
No. Several things keep working after the first year.
- Ongoing depreciation. The remaining building basis keeps depreciating on its normal schedule. Smaller than year one, but still a deduction.
- Carryforward losses. If your year-one loss is larger than the income it can offset, the unused amount does not vanish. It carries forward to future years (subject to the excess business loss limit under IRC §461(l), with the excess becoming a net operating loss under IRC §172).
- You control the timing. You can elect out of bonus depreciation by asset class under IRC §168(k)(7), or simply carry losses forward, so a strategist can spread the benefit across the years you need it most.
So a single well-bought STR can keep reducing your taxes for years, even without another purchase.
When would I actually need to buy another STR?
When you have a high income every single year and want to keep driving it down. The first-year depreciation spike is a one-time event per property. If you earn $300K+ annually and want to keep offsetting it, you generally need new depreciable basis each year. That can come from a new property, but it does not have to.
| Goal | Do you need a new STR? |
|---|---|
| Offset one big income year (bonus, RSU vest, business sale) | No, one property's year-one deduction can carry forward |
| Steadily reduce a high W-2 income every year | Often yes, or add depreciable improvements each year |
| Build a portfolio over time | Buy on your timeline, not the tax calendar |
You do not have to launch on a tax-driven schedule. Because losses carry forward and you can elect when to use them, spreading purchases out for "tax timing" is usually unnecessary. Buy when the deal and the operations make sense. For scaling considerations, see our guide on the STR loophole with multiple properties.
Can I get new deductions without buying another property?
Yes, through improvements to a property you already own, sometimes called land-hacking. New depreciable assets you add are deductible, and many qualify for bonus depreciation.
- Build a second cabin or accessory unit on the lot
- Add a pool, hot tub, or pickleball court
- Remodel a kitchen or renovate a section of the home
For documented new construction and rehabs, you often do not even need a second cost segregation study. A detailed record of dated line items, labor, and materials gives your CPA what they need to bonus-depreciate the work. That lets you keep generating deductions from one property over multiple years instead of buying a new one each time.
The Bottom Line: One STR is not a one-and-done. Carryforward losses, ongoing depreciation, and depreciable improvements all extend the benefit, so buy another property only when your income or strategy calls for it, not because the calendar flipped.
