A single-family rental in Cordillera Ranch, a couple of acres of Hill Country outside Boerne, leased to a long-term tenant, throws off steady rent. On paper it also throws off a tax bill, and Texas takes nothing while the IRS still takes plenty. A cost segregation study can produce a $159K first-year deduction that lands squarely against that rental income. That’s the Boerne play: put the deduction where the income is.
Why Boerne is its own kind of Hill Country market
Boerne isn’t Fredericksburg, and it isn’t New Braunfels. Fredericksburg is wine-country short-term-rental territory; New Braunfels runs on river-tubing vacation rentals. Boerne is the affluent bedroom community, the Hill Country gateway just northwest of San Antonio, with German heritage on the historic Hauptstrasse, Cibolo Creek running through downtown, top-rated schools, and large-acreage estates in developments like Cordillera Ranch.
That profile changes what gets rented. The Boerne inventory skews toward luxury single-family rentals, small multifamily, Hill Country second homes, and some vacation rentals, often on generous lots with real site work. Those large lots matter for cost segregation, because acreage, driveways, fencing, and outdoor systems are exactly the land improvements an engineering-method study reclassifies into faster depreciation schedules. A Fair Oaks Ranch or Tapatio Springs property with a long private drive and fenced acreage carries more of this reclassifiable value than a small in-town lot, and that difference flows straight through to the size of the Year-1 deduction.
Who’s buying, and the combined rate
The Boerne buyer pool is affluent professionals, San Antonio business owners, physicians, and executives building a Hill Country real-estate position, plus out-of-state buyers drawn by 0% Texas state income tax. Whatever the persona, the tax stack is the same:
Verify with your CPA — combined-rate math depends on filing status and AGI thresholds for NIIT.
What accelerates on a Boerne rental
The engineering method walks the property and separates the building shell from everything that depreciates faster:
- 5-year property: appliances, furnishings, and equipment like a private well pump or irrigation system.
- 15-year land improvements: driveways, fencing, gravel and site work, and landscaping, when owned and included in the depreciable basis.
On a large Hill Country lot, that 15-year bucket is often bigger than a suburban comp would suggest: the acreage carries more site work, more fencing, and more landscaping to reclassify.
A representative worked example
A representative Boerne single-family Hill Country rental bought for $660K. After carving out land, the $495K adjusted basis breaks down into roughly $98K of 5-year assets (appliances, furnishings, well and irrigation equipment), $3K of 7-year assets (casework and specialty items), and $58K of 15-year property (driveway, fencing, gravel site work, and landscaping owned and included in basis).
That’s $159K reclassified into accelerated depreciation in Year 1. At ~40.8%, federal + NIIT savings come to about $65,000.
Because a Boerne property is often a long-term rental, that deduction generally shelters rental income and any excess passive loss carries forward against future rental income or gain at sale. Whether any of it can offset your other income in the current year depends on your specific facts: the short-term-rental exception, real estate professional status, or the passive-loss rules. Your CPA confirms which applies before you file.
Long-term rental, short-term rental, or REPS
The deduction is the same size regardless; what changes is when and against what you can use it.
- Long-term rental: the most common Boerne case. The deduction shelters rental income; unused passive losses carry forward. No hours test to worry about, but the loss generally can’t offset W-2 or business income until you have passive income or sell.
- Short-term rental: a Boerne vacation rental with a 7-day-or-less average guest stay can qualify under the STR exception (Reg. §1.469-1T(e)(3)(ii)) with 100 hours of material participation, opening up the deduction against non-passive income.
- Real Estate Professional Status: if you or a spouse meets the 750-hour and more-than-half-your-time tests, the losses can offset ordinary income.
Which lane you’re in is a facts-and-circumstances call your CPA makes. The study is worth doing in all three; it just determines the timing of the benefit.

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 Boerne, TX investors choose a cost segregation provider?
For a Boerne, TX investor buying a property in the $660,000 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 Boerne, 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 Boerne, 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.
