San Antonio's Rental Market Is Quietly One of the Best in Texas
San Antonio doesn't get the attention that Austin, Dallas, or Houston command from real estate investors. That's part of what makes it compelling. The median home price in Bexar County sits around $290,000 as of early 2026—roughly half of what you'd pay in Austin for a comparable property. Meanwhile, rental demand stays consistently strong, driven by Joint Base San Antonio (JBSA), four military installations, a growing healthcare sector anchored by the South Texas Medical Center, and steady population growth that's added over 200,000 residents to the metro area in the past five years.
For investors, the math is straightforward: lower entry prices, solid rents, and a tenant base that includes military personnel on housing allowances and healthcare workers with stable incomes. But most San Antonio investors are still depreciating their properties over 27.5 years using straight-line depreciation—the default method. That means they're spreading their tax deductions evenly over nearly three decades instead of accelerating a significant portion into Year 1.
A cost segregation study changes that equation. And with 100% bonus depreciation permanently restored under the One Big Beautiful Bill Act, the Year 1 impact is at its highest possible level.
How Cost Segregation Works for San Antonio Properties
Cost segregation is an engineering-based analysis that reclassifies components of your property from 27.5-year (residential) or 39-year (commercial) property into shorter depreciation categories: 5-year, 7-year, and 15-year property. Things like appliances, cabinetry, flooring, fixtures, landscaping, driveways, fencing, and site improvements all qualify for shorter recovery periods under IRS MACRS guidelines.
With 100% bonus depreciation, every dollar reclassified to these shorter categories can be deducted in full in Year 1. For a San Antonio rental purchased for $350,000, that can mean $50,000-$70,000 in accelerated deductions instead of $10,000 per year in straight-line depreciation. At a 32% federal tax rate, that's potentially $16,000-$23,000 in tax savings from a study that starts at $795.
Texas has no state income tax, but you still pay federal tax on rental income. San Antonio investors in the 32%+ bracket are leaving five figures in tax savings on the table if they haven't done a cost segregation study.
The Military-Town Advantage
San Antonio's military presence creates a unique rental dynamic. JBSA includes Fort Sam Houston, Lackland AFB, and Randolph AFB—three installations that cycle thousands of military families through the area every year on PCS (permanent change of station) orders. These tenants typically need housing for 2-4 year tours, pay with BAH (Basic Allowance for Housing) stipends, and are reliable renters.
For investors, this means consistent occupancy and predictable income. But it also means consistent taxable rental income that you're paying federal taxes on. Cost segregation reduces that tax burden by accelerating depreciation deductions into the early years of ownership, when the time value of money is highest.
Many military-area investors own multiple properties—two, three, or four rentals near different bases or in different neighborhoods. Each property can benefit from its own cost segregation study. The cumulative tax impact of accelerating depreciation across a small portfolio can be substantial.
A Real Example: 3BR Rental Near Fort Sam Houston
The property: A 3-bedroom, 2-bathroom single-family rental in Terrell Hills (78209), purchased in January 2024 for $345,000. Built in 2008. Rented to a military family at $1,950/month. The owner is a dentist with practice income of $310,000.
Without cost segregation: Depreciable basis (purchase price minus land, approximately 18% for Bexar County) is about $283,000. Straight-line depreciation: $10,290 per year.
With cost segregation:
| Category | Amount | Year 1 Deduction |
|---|---|---|
| 5-Year Property (appliances, cabinetry, flooring, fixtures, ceiling fans) | $50,900 | $50,900 (100% bonus) |
| 15-Year Property (landscaping, driveway, sidewalks, fencing, patio) | $22,600 | $22,600 (100% bonus) |
| 27.5-Year Property (remaining building structure) | $209,500 | $7,618 (straight-line) |
| Total Year 1 Accelerated Deductions | $73,500 |
At a 35% effective federal rate, that $73,500 in Year 1 deductions translates to approximately $25,700 in estimated tax savings. On a $795 study, that's a 32x return on investment.
San Antonio Neighborhoods: How Location Affects the Math
San Antonio's construction cost index runs at approximately 0.85 relative to the national average—one of the lower figures among major metros. This is actually favorable for cost segregation because it means your property's component costs aren't inflated by high-cost labor markets. The ratio of reclassifiable components to total basis tends to be healthy.
Alamo Heights / Terrell Hills (78209): The most established investment neighborhood in San Antonio. Older homes (many pre-1970) with higher purchase prices, typically $400K-$700K. Older construction generally produces higher reclassification percentages because the building systems, fixtures, and site improvements represent a larger proportion of the total cost. Renovated properties in this area are especially good candidates.
Stone Oak / Canyon Springs (78258, 78259): Newer master-planned communities on the far north side. Purchase prices in the $350K-$550K range. Popular with military officers and medical professionals. Newer construction has slightly lower reclassification percentages, but the absolute dollar amounts remain significant.
Southtown / King William (78204): San Antonio's arts and restaurant district, increasingly popular for STR investment. Older historic homes that have been renovated. These properties often see strong reclassification rates, particularly when renovation costs include new fixtures, flooring, and kitchen/bath upgrades.
Far West Side / Helotes area (78253, 78254): Rapid new construction. Purchase prices in the $280K-$400K range. Strong rental demand from Lackland AFB personnel. Even at these more moderate price points, cost segregation generates meaningful Year 1 deductions.
Near Randolph AFB / Schertz / Cibolo (78108, 78154): Suburban communities popular with military families. Median around $300K-$350K. Consistent rental demand, low vacancy rates. The combination of reliable income and accelerated depreciation makes the after-tax return profile especially attractive.
The STR Angle: River Walk and Beyond
San Antonio's short-term rental market is smaller than Austin's but growing. The River Walk, Pearl District, and downtown areas draw consistent tourism, and the city processes over 30 million visitors per year. STR permits are required in San Antonio, and the city has been relatively investor-friendly compared to Austin's restrictive approach.
For STR owners who materially participate (100+ hours per year managing the property), cost segregation deductions become non-passive. That means they can offset your W-2 income, your practice income, your business profits—not just other rental income. For a dentist, physician, or business owner operating a downtown San Antonio STR, this is a particularly powerful strategy.
Furnished STR properties generate the highest reclassification percentages because all the furniture, decor, kitchen equipment, and electronics are 5-year property. A fully furnished downtown STR might see 26-30% of depreciable basis accelerated to shorter categories.
100% Bonus Depreciation and the Lookback Opportunity
If you purchased your San Antonio property in 2021, 2022, or 2023 and have been using straight-line depreciation, you can still capture the accelerated deductions through a lookback study. Your CPA files a Form 3115 (change in accounting method), and all the accumulated missed accelerated depreciation flows into your current-year return as a single catch-up adjustment. No amended returns needed.
The One Big Beautiful Bill Act permanently restored 100% bonus depreciation for 2025 and beyond. During the 2023-2024 phase-down (80% and 60% respectively), many investors waited. The waiting is over. The full 100% deduction is available now.
Getting Started
The process takes minutes. You provide your property address, purchase price, property type, year built, and any notable improvements. We deliver an engineering-based cost segregation report—typically 30-40 pages—with component-level depreciation schedules and IRS-compliant MACRS classifications. Your CPA applies the report directly to your tax return.
San Antonio's combination of affordable entry prices, strong rental demand, and zero state income tax creates an environment where every federal tax dollar you save goes directly to your bottom line. If you own a rental property in the San Antonio metro and you're still using straight-line depreciation, the math says you're overpaying on your federal taxes. A cost segregation study starting at $795 can change that.
