Walk the back terrace of a Lake Travis waterfront rental in Rough Hollow and you’ll pass a pool and spa, a boat lift on the dock, an outdoor kitchen, and a run of hardscape stepping down to the water. On paper it depreciates like any other house: one slow 27.5-year line. But that property is nothing like a plain suburban rental, and the tax code lets you prove it.
A cost segregation study can produce a $166K first-year deduction on a property like this. That’s the Lakeway play in one sentence: your edge is what the property is made of, not just your tax bracket.
Why cost segregation pays off on a Lake Travis property
Here’s the insight most Lakeway owners miss: your edge is property composition (the waterfront and amenity stack), not your bracket alone.
Texas’s 0% state tax caps your combined rate at ~40.8% (federal 37% + NIIT 3.8%), the same ceiling every Texas resident hits. So the multiplier on a reclassified dollar is fixed. What varies, and what actually moves the number, is how much of the property qualifies for accelerated depreciation in the first place. A Lake Travis estate with a pool, a dock, an outdoor kitchen, and terraced hardscape simply has more 5- and 15-year property to find than a builder-grade interior-only home.
A cost segregation study produces its biggest deduction in Year 1. On an amenity-dense waterfront or golf-community rental, that first-year number is large precisely because the property carries so many short-life components. The Lakeway playbook is less “what’s my bracket” and more “how much of this estate is really 5- and 15-year property.”
Who’s buying, and the combined rate
Lakeway and the surrounding Lake Travis corridor draw Austin’s tech and executive wealth: founders and senior engineers cashing out equity, Austin tech transplants, and professionals buying second homes and rentals in the golf communities (Lakeway Resort, Flintrock Falls, and The Hills) and along the waterfront. All of them face the same simple stack:
Verify with your CPA — combined-rate math depends on filing status and AGI thresholds for NIIT.
What we generally reclassify on a Lakeway estate
On a Lake Travis waterfront or golf-community rental, the short-life property clusters in two buckets:
- 5-year (§1245) assets: appliances, pool and spa equipment, boat-lift and dock hardware, furnishings, and smart-home systems.
- 15-year (land improvements): the pool deck, the dock, retaining walls, hardscape, and landscaping (only when owned and included in basis).
Casework, wall finishes, and specialty electrical often move too. The waterfront-plus-amenity combination is what makes these properties reclassify a larger share of basis than a standard interior-only home; the components are simply there to find.
A representative worked example
A representative Lake Travis waterfront rental, bought for $760K in Rough Hollow. After land, the $570K adjusted basis breaks down into roughly $105K of 5-year assets (pool and spa equipment, boat-lift and dock hardware, appliances, smart-home, and furnishings), $3K of 7-year assets, and $58K of 15-year property (pool deck, dock, retaining walls, hardscape, and landscaping owned and included in basis).
That’s $166K reclassified into accelerated depreciation in Year 1, roughly 29% of the $570,000 depreciable basis. At ~40.8%, federal + NIIT savings come to about $68,000. Whether you can use the full deduction against other income in Year 1 depends on your material-participation and passive-activity facts; confirm the timing with your CPA.
Beyond waterfront: who else this fits
The same math runs across the Lakeway market:
- Luxury and waterfront rentals: the flagship case, with the deepest amenity stack.
- Golf-community SFR in The Hills, Flintrock, and Serene Hills: outdoor kitchens, hardscape, and premium finishes.
- Small multifamily in and around Cedar Park and the corridor: per-unit finishes and site improvements add up.
- Second-home conversions in Dripping Springs and the Hill Country: when a personal residence becomes a rental, the depreciable basis is set at fair market value on the conversion date.
Who doesn’t qualify
If a Lakeway property is a short-term rental, the path to using the deduction against other income is the STR exception (Reg. §1.469-1T(e)(3)(ii)): a 7-day-or-less average guest stay plus 100 hours of material participation where no one else participates more. For a longer-term rental, the deduction is generally passive unless you qualify for Real Estate Professional Status or have offsetting passive income.
Living near the property helps: an owner managing a Lake Travis rental hands-on can more easily clear the hours than an absentee investor. But the hours must come substantially from you, not solely a property manager. Confirm your facts with your CPA.

Tax law current as of July 2026. Federal: OBBBA restored 100% bonus depreciation under §168(k), permanent for property both acquired and placed in service after January 19, 2025 (property acquired or placed in service on or before that date remains under the prior 40% phase-down); 2026+ stays 100%. State conformity varies; verify with your CPA.
CPA use note: These figures estimate the size of the depreciation deduction. Whether the loss is usable in the current year depends on passive-activity rules, STR material participation, REPS status, entity structure, depreciable basis, and state conformity — your CPA decides how and when it is applied. Specialty and site components (equipment, casework, docks, pools, arenas, tenant improvements, and similar) are only classified when you own them and they are included in the depreciable basis being studied.
How should Lakeway, TX investors choose a cost segregation provider?
For a Lakeway, TX investor buying a property in the $760,000 range, the choice of study provider is the single biggest controllable variable in the ROI. The methodology is fixed by IRS Audit Techniques Guide rules (industry-standard construction cost data, MACRS classification, engineering-based component reclassification) — what varies is delivery cost and turnaround time.
Traditional engineering studies often run several thousand dollars and can take several weeks, because they include on-site inspections, sales discovery calls, and scheduling overhead. The IRS Cost Segregation Audit Techniques Guide does not require a physical site visit; it requires engineering-based classification with industry-calibrated cost derivation and component-level documentation.
Modern automated providers (such as Cost Seg Smart) deliver the same IRS ATG–aligned study for $495–$1,595 in under one hour, using satellite imagery, county assessor data, and the same industry-standard construction cost databases. For a Lakeway, TX investor at the metro's combined bracket, that cost delta typically exceeds the study cost itself by several times over. The CPA-Ready Guarantee (full refund if the report can't be used by your CPA) plus the 60-day money-back policy makes the decision essentially risk-free on the report itself.
The automated path is best-fit for Lakeway, TX investors who: own residential STR property valued under $2M, are comfortable uploading closing docs + property photos online (no in-person visit required), and want the report in time to file the current year's return rather than the next one.
All Cost Seg Smart studies include the CPA-Ready Guarantee (full refund if your CPA can't use the report) plus a 60-day money-back policy. Reports are delivered in under one hour with no on-site visit required.
