San Antonio is the seventh-largest city in the United States by population and the second-largest in Texas, yet it remains one of the more affordable major metros in the state. While Austin and Dallas have captured most of the national attention (and experienced the sharpest corrections), San Antonio has quietly grown at a steady pace, supported by its massive military presence, USAA's corporate headquarters, Toyota manufacturing, and a growing healthcare and cybersecurity sector. The median home price in Bexar County is approximately $244,000 (Zillow ZHVI, early 2026) — roughly half of Austin's Travis County median.
The San Antonio-New Braunfels MSA population is approximately 2.65 million (U.S. Census Bureau, 2024 estimates), and the metro has been one of the fastest-growing in the country, adding approximately 50,000–60,000 residents per year over the past decade. That growth, combined with Texas's no-state-income-tax advantage and San Antonio's relative affordability, creates a compelling investment thesis. But investors must account for Texas's high property taxes and understand the submarket dynamics.
Why San Antonio: Economic Fundamentals
San Antonio's economy is anchored by military and defense, healthcare, financial services, manufacturing, and tourism. The unemployment rate was approximately 4.0% as of Q4 2025 (BLS LAUS). Median household income is approximately $64,800 (Census ACS, 2023 5-year estimates). The cost of living index (C2ER) is approximately 93 — below the national average and significantly below Austin (105) or Dallas (100).
Military City USA: The Five Major Installations
San Antonio's military presence is unmatched by any metro in the country. The five major installations create a recession-proof demand base that drives the rental market:
- Joint Base San Antonio (JBSA): JBSA consolidates three formerly separate installations — Fort Sam Houston, Lackland AFB, and Randolph AFB — under a single joint base command. Combined, JBSA is the largest DoD joint base in the United States.
- Fort Sam Houston: Home of the U.S. Army Medical Command (MEDCOM) and Brooke Army Medical Center, one of the military's largest medical facilities. Approximately 30,000 military and civilian personnel.
- Lackland AFB: The “Gateway to the Air Force” — all Air Force and Space Force enlisted basic training occurs here. Approximately 25,000 personnel plus approximately 80,000 trainees annually cycling through.
- Randolph AFB: Home of Air Education and Training Command headquarters and the 12th Flying Training Wing. Approximately 10,000 personnel.
- Camp Bullis: Military training reservation north of San Antonio used by all branches. Approximately 2,000 permanent personnel.
Combined, the San Antonio military community includes approximately 80,000 active duty, reserve, and civilian defense employees, plus approximately 250,000 military retirees in the metro area. Total defense-related economic impact exceeds $40 billion annually. This creates enormous, consistent rental demand, particularly for 3–4 bedroom single-family homes near base gates.
Other Key Economic Drivers
- USAA: USAA, the financial services company serving military members and their families, is headquartered in San Antonio with approximately 19,000 local employees. USAA is the largest private employer in the metro.
- Toyota Motor Manufacturing: Toyota operates a major truck assembly plant in south San Antonio (Tundra and Sequoia) employing approximately 3,200 directly plus thousands of supply chain workers.
- Healthcare: San Antonio has a large medical sector beyond the military hospitals, including University Health System, Methodist Healthcare, and Baptist Health System. The South Texas Medical Center campus is one of the largest medical complexes in the country.
- Cybersecurity: San Antonio has emerged as a major cybersecurity hub, driven by the military presence (NSA Texas, 24th Air Force Cyber Command). The “Cyber City USA” brand has attracted private-sector cybersecurity firms and federal contractors.
- Tourism: The Alamo, River Walk, and San Antonio Missions National Historical Park draw approximately 35 million visitors annually, generating approximately $17 billion in economic impact.
Home Prices: The Texas Affordability Leader
San Antonio is the most affordable major metro in Texas:
- Bexar County median home price: Approximately $244,000 (Zillow ZHVI, early 2026)
- Northwest San Antonio (UTSA area, Leon Valley): $230,000–$310,000
- Northeast San Antonio (Converse, Live Oak, near Randolph): $220,000–$300,000
- South San Antonio (near Lackland, Toyota): $160,000–$230,000
- Far northwest (Helotes, Fair Oaks Ranch): $350,000–$500,000
- New Braunfels (Comal County, I-35 corridor): $310,000–$400,000
- San Antonio proper (inner city, near Fort Sam Houston): $150,000–$250,000
For comparison: Austin's Travis County median is approximately $488,000, and Dallas County's is approximately $310,000. San Antonio offers 20–50% lower entry prices than its Texas peers, making it significantly more accessible for cash-flow investors.
The FHFA House Price Index shows approximately 6.2% annualized appreciation for the San Antonio MSA over the 5-year period ending Q3 2025. Appreciation moderated to 3–5% in 2024–2025. San Antonio experienced a mild correction of approximately 3–5% from the 2022 peak — much less severe than Austin's 12–15% pullback.
Tax Environment: No Income Tax, High Property Tax
Texas's tax structure is the defining factor for real estate investors:
- No state income tax: Texas does not tax personal or corporate income. This is the state's headline advantage for investors and high-income earners.
- Property tax rate (Bexar County): Approximately 1.97% effective rate — one of the highest in the country. This is how Texas funds government services in lieu of an income tax.
- Property tax on a $244,000 home (metro median): Approximately $4,807 annually, or $401/month
- Property tax on a $200,000 rental: Approximately $3,940 annually, or $328/month
Important: Texas property taxes on investment properties are assessed at full market value with no homestead exemption. Owner-occupants receive a homestead exemption that reduces their taxable value by $100,000 (for school district taxes). Investors do not receive this exemption, so the effective tax rate on investment properties is higher than what owner-occupants pay. Always use the non-homestead rate when modeling investment returns.
The net tax impact: Texas's no-income-tax advantage is partially offset by the high property tax. For a $244,000 rental generating $18,000 in net income, an investor in a 5% income tax state would pay $900 in state income tax — while the Texas investor saves that $900 but pays approximately $2,000–$3,000 more in property taxes than they would in a lower-property-tax state. The breakeven depends on your income level and the specific comparison state.
Rental Yields: Moderate Cash Flow
- Gross yield (affordable areas, $150K–$230K): 8–11%
- Gross yield (mid-range, $230K–$310K): 6–8%
- Gross yield (premium suburbs, $310K+): 5–6.5%
- Cap rate (stabilized, after property tax): 5–7% depending on submarket
- Cash-on-cash return (25% down, 7.0%): 3–7%, with the high property tax reducing CoC by 1.5–2.5% compared to lower-tax markets
San Antonio's gross yields are attractive, but the 1.97% property tax is a significant drag on net returns. A $240,000 San Antonio rental paying $4,728 in property taxes loses $200/month more in taxes than an identical property in Indianapolis (0.85% tax rate, $2,040 annual tax on the same value). This property tax drag is the key disadvantage of Texas markets relative to Midwest alternatives.
Insurance Costs
- Average annual DP-3 landlord policy: $2,200–$3,200 for a typical single-family rental
- Average for investment purposes: Approximately $2,700
San Antonio faces moderate natural hazard risk. Hail and severe thunderstorms are the primary concerns — San Antonio is on the eastern edge of the Texas hail belt. Tornado risk is lower than Oklahoma City or Dallas but still present. Flash flooding occurs during heavy rain events, particularly along waterways and low-lying areas. Always verify FEMA flood zone status. Insurance costs are elevated compared to the national average but lower than Oklahoma or coastal Texas markets.
Key Submarkets for Investors
Near Lackland AFB (South/Southwest SA)
The neighborhoods surrounding Lackland AFB — including Westover Hills, Marbach, and parts of southwest Bexar County — are the primary rental market for Air Force personnel. Home prices of $160,000–$230,000, 3BR rents of $1,300–$1,600, and gross yields of 8–10% are typical. Tenant demand is driven by military personnel (active duty and civilian), many of whom use Basic Allowance for Housing (BAH) to pay rent. BAH rates for San Antonio E-5 with dependents are approximately $1,650/month (2025), providing a reliable rent benchmark. Schools rate 3–6/10. Crime varies by neighborhood.
Near Randolph AFB (Northeast / Converse / Live Oak)
The northeast corridor near Randolph AFB offers a slightly higher-quality rental market. Home prices of $220,000–$300,000, 3BR rents of $1,500–$1,900, and gross yields of 7–9%. Schools are better in this area (5–7/10), particularly in the Judson and Schertz-Cibolo-Universal City ISDs. Crime is moderate to low. The Converse and Live Oak areas are popular with military families who want good schools and a suburban feel.
Northwest San Antonio (UTSA Corridor)
The UTSA/I-10 West corridor has seen significant growth driven by University of Texas at San Antonio expansion, medical center employment, and commercial development. Home prices of $250,000–$340,000, with 3BR rents of $1,600–$2,000. Gross yields of 6–8%. This area offers a balance of cash flow and appreciation, with strong demand from healthcare workers, university employees, and young professionals.
New Braunfels and the I-35 Corridor
New Braunfels (Comal County), approximately 30 miles northeast of San Antonio on I-35, has been one of the fastest-growing cities in the country. Home prices of $310,000–$400,000 with 3BR rents of $1,800–$2,200. Gross yields of 6–7%. Comal County property taxes (approximately 1.70%) are slightly lower than Bexar County. Schools are excellent (7–9/10 in Comal ISD). Schlitterbahn waterpark and Guadalupe River tubing create seasonal STR opportunities.
Landlord-Tenant Laws
Texas is among the most landlord-friendly states:
- Eviction for nonpayment: 3-day notice to vacate (can be as short as 1 day if the lease specifies). After the notice period, landlord files forcible detainer in justice court. Hearings are typically scheduled within 10–21 days. Total process is typically 3–5 weeks.
- Rent control: Texas state law expressly prohibits local rent control ordinances.
- Security deposit: No statutory limit on the amount. Must be returned within 30 days of move-out.
- Property code protections: Texas Property Code Chapter 92 governs residential landlord-tenant relationships. Landlords must maintain the property in a habitable condition but have broad discretion in lease terms.

Acquisition
- Purchase price (3BR/2BA, 2000s construction, near Lackland): $210,000
- Closing costs (3%): $6,300
- Minor repairs: $3,000
- Total invested: $219,300
Monthly Income and Expenses
- Monthly rent: $1,550
- Vacancy (6%): -$93
- Property management (8%): -$124
- Maintenance (5%): -$78
- CapEx reserve (5%): -$78
- Property taxes (1.97% of $210K = $4,137/yr): -$345
- Insurance ($2,700/yr): -$225
- Mortgage P&I ($157,500 at 7.0%, 30-year): -$1,048
- Net monthly cash flow: -$441
At 75% LTV and 7.0%, this Lackland-area property is cash-flow negative. The property tax ($345/month) is the primary drag. At 30% down and 6.5%, cash flow improves to approximately -$100/month — still negative. Positive cash flow requires either a lower purchase price ($180K range), a higher rent ($1,700+), or a larger down payment (35%+). San Antonio's property taxes make breakeven cash flow harder to achieve than in lower-tax Midwest markets at current interest rates. The no-income-tax advantage partially offsets this for higher-income investors.
San Antonio vs. Other Texas Markets
- vs. Austin: San Antonio is approximately 50% cheaper (median $244K vs. $488K), has stronger cash-flow potential, and has a more stable (less volatile) market. Austin has stronger appreciation potential and a more dynamic tech economy. For cash-flow investors, San Antonio is clearly superior. For appreciation and long-term growth, Austin has the edge if you can weather the volatility.
- vs. Dallas-Fort Worth: DFW has a larger, more diversified economy and stronger appreciation history. San Antonio is approximately 20% cheaper and has the military demand base that DFW lacks. Both have similarly high property taxes. DFW is the balanced play; San Antonio is the affordability and military-demand play.
- vs. Houston: Houston has more economic diversity (energy, medical center, port) and a larger metro. San Antonio is more affordable and has lower insurance costs (Houston faces significant hurricane and flood risk). Both markets work for investors, but Houston requires more careful flood zone analysis.
What to Watch Out For
- Property taxes: The 1.97% effective rate is the single biggest challenge for San Antonio investors. Always model with actual tax assessments, not estimates. Protest your tax assessment annually — successful protests can save $500–$1,500 per year per property.
- Military drawdown risk: While JBSA is considered a “power projection platform” unlikely to face major cuts, any significant defense spending reduction would impact the San Antonio economy. Base Realignment and Closure (BRAC) risk is low but not zero.
- Foundation issues: San Antonio's expansive clay soils (particularly the black gumbo clay on the south side) cause foundation movement. Foundation repairs can cost $5,000–$25,000. Get a foundation inspection on every purchase.
- SAWS water rates: San Antonio Water System (SAWS) rates are among the highest in Texas. Budget for higher water costs, particularly if landscaping requires irrigation.
- HOA restrictions: Many newer subdivisions in San Antonio have restrictive HOAs that prohibit or limit rentals. Always verify HOA rental policies before purchasing.
Bottom Line: Is San Antonio Right for You?
San Antonio is the right market if you want exposure to the Texas no-income-tax advantage at a price point that is actually affordable. The military demand base provides recession-proof rental demand, the economy is diversifying beyond defense, and population growth is strong and sustained. San Antonio is the most accessible Texas market for cash-flow investors.
San Antonio is the wrong market if you expect the property tax math to work like a Midwest market. The 1.97% effective rate means you need either below-market purchase prices, above-average rents, or larger down payments to achieve positive cash flow at current interest rates. Investors accustomed to 0.85–1.0% property tax rates will find the San Antonio proforma sobering.
The ideal San Antonio investor values military-driven demand stability, is comfortable with the high property tax trade-off against no income tax, targets properties near the major base gates where BAH-driven rent is reliable, and protests tax assessments annually. If you underwrite conservatively with realistic tax and insurance figures, San Antonio offers steady returns in a growing metro with strong long-term fundamentals.
