30-Second Answer
Cost segregation works for any Austin investment property over $100K — that's our company line. The math gets best when you (1) use the property as a short-term rental, (2) materially participate in operations (100+ hours/year), and (3) have meaningful taxable income to absorb the deductions. For typical qualified Austin STR owners, year-one federal tax savings commonly land in the $25K–$200K range depending on property value. Run the 5-question calculator below for an exact number on your situation.

The numbers behind Austin STR cost seg
Modeled from Cost Seg Smart's recent Austin-area engagements (Travis & Williamson counties), aligned to the 2026 Cost Seg Smart benchmarks dataset (n=260 studies across 13 property types).
- STR loophole legal basis: Treas. Reg. §1.469-1T(e)(3)(ii) — properties with avg. stay <7 days are not "rental activity" under §469.
- Material participation: IRC §469(h) — 100+ hours/year, more than anyone else.
- 100% bonus depreciation: Permanently restored under OBBBA (signed July 2025) for property placed in service after Jan 19, 2025.

THE HONEST ANSWER
Sometimes it's not worth it.
We'd rather lose your business than sell you a study you don't need. If any of these match you, reconsider.
Property under $100K
Below $100K, even a $495 automated study can't reliably pay back. That's our floor — every investment property over $100K is worth a study at costsegsmart.com pricing.
You don't materially participate
Without 100+ hours and STR-specific use, losses get suspended as passive — they can't offset W-2 income.
Selling within 2–3 years
Depreciation recapture on sale will largely offset the upfront benefit. Cost seg favors holds of 5+ years.
No taxable income to shelter
Deductions can't go negative. If your AGI is already low, the math doesn't work — and unused losses carry forward.
Long-term rental, low income
The STR loophole is what makes this powerful. Long-term rentals see roughly half the year-1 benefit.
Already 10+ years owned
Most accelerated depreciation has already been taken via straight-line — the study has less to find.

FREQUENTLY ASKED
Common Austin STR cost seg questions.
Is cost segregation worth it for an Austin Airbnb?
Cost Seg Smart's company line is that cost segregation works for any Austin investment property over $100K. The math gets best with STR use, material participation, and meaningful taxable income. For typical qualified Austin STR owners, year-one federal tax savings commonly land in the $25K–$200K range depending on property value. The calculator above gives you an exact number on your specific inputs.
What is the STR loophole and why does it matter?
Properties with average guest stays under 7 days are not treated as rental real estate under Treas. Reg. §1.469-1T(e)(3)(ii). With material participation (IRC §469(h) — 100+ hours/year, more than anyone else), the resulting losses are non-passive and can offset W-2 or business income. This is what makes cost segregation powerful for Austin Airbnb owners.
Why is Austin different from other STR markets?
Three things: (1) permitting volatility — Austin's Type 2 STR rules have been challenged and rewritten repeatedly; (2) wide neighborhood spread — a $700K East Austin bungalow has a different cost-seg profile than a $700K Cedar Park rental; (3) no Texas state income tax, so deductions only offset federal — high-income owners are the cleanest fit.
How much does an Austin cost segregation study cost?
For Austin STRs at Cost Seg Smart, automated engineered studies start at $495 for properties under $300K, $795 ($300K–$700K), $895 ($700K–$1M), $1,295 ($1M–$2M), $1,595 ($2M–$5M). Traditional firms typically quote $3,500–$8,000 for the same property — see costsegregationpricing.com for the full 2026 market survey.
Is 100% bonus depreciation back?
Yes. The One Big Beautiful Bill Act (signed July 2025) permanently restored 100% bonus depreciation for qualifying property placed in service after January 19, 2025. All 5-, 7-, and 15-year components reclassified by a cost segregation study can be fully expensed in year one.
What if I bought my Austin Airbnb several years ago?
You can still do a lookback study. IRS Form 3115 (change in accounting method) lets you claim catch-up depreciation as a Section 481(a) adjustment in the current tax year — no amended returns required. The study has less to find on properties owned 10+ years, but it's still often worthwhile in the 2–7 year window.
