Updated 2026 · Based on median market data for San Antonio, TX
Austin gets the headlines, Dallas gets the corporate relocations, Houston gets the energy money, and San Antonio quietly grew to roughly 1.5 million residents while everyone was looking somewhere else. That is the entire investment thesis in one sentence. The seventh-largest city in the United States, sitting at a median home price near $275,000 with median rents around $1,390 and a metro cap-rate signal in the 3.13% range, is fundamentally a different kind of Texas market than its three more-famous cousins. It is older, more military, more Mexican-American, slower-growing, and substantially cheaper. Population growth here is about 1.20% a year — less than Austin's peak but steadier and with fewer of the boom-bust dynamics. For a buy-and-hold investor allergic to Austin valuations and tired of the Houston-Dallas dogfight for inventory, San Antonio quietly delivers some of the most stable risk-adjusted yields in Texas.
Joint Base San Antonio is the largest single-installation employer of the Department of Defense in the country, anchoring four major sites: Lackland Air Force Base, Randolph Air Force Base, Fort Sam Houston, and Camp Bullis. Together they put roughly 80,000 active-duty service members, civilian DoD employees, and contractors into the rental market on a perpetual rotation, with BAH (Basic Allowance for Housing) for an E-5 with dependents currently around $1,529 a month. That BAH number is not a coincidence: it tracks local rents and effectively sets the floor for one-to-three-bedroom housing in any zip code within commuting range of a base. If you are buying within 15 minutes of Lackland, Randolph, or Fort Sam, you have a tenant pool that arrives with a guaranteed housing budget, gets relocated every two to four years, and rarely breaks leases without a PCS order. That is structurally different than civilian renting, and once you understand the orbit of military families around each base, you stop competing with other landlords on the same listings.
Inside Loop 410, the math gets harder every year. The South Side neighborhoods between downtown and Loop 410 — including parts of Highland Park, Harlandale, and the area east of South Flores — still occasionally print one-percent deals on smaller post-war SFRs, especially three-bedroom one-bath homes that need cosmetic work. The West Side, west of Zarzamora, is the cheapest part of the city by far and rents to a working-class Hispanic tenant base that has been there for generations; cap rates can look attractive on paper but property management requires Spanish-speaking competence and a real understanding of the neighborhood. The Northeast around Windcrest and Live Oak is the workhorse military-rental zone — modest 1970s-1990s tract homes, easy financing, low drama, 2.98%-3.13% caps and reliable BAH-priced rents. The far Northwest around Leon Valley and the Medical Center area trades higher per door but pulls hospital-system tenants and is the closest thing San Antonio has to a defensive growth play.
Stone Oak, the master-planned communities along Highway 281 north of 1604, and the newer growth in Cibolo, Schertz, and Selma operate on completely different math than the rest of the city. Median sale prices in these zip codes can run $440,000 or more for a recent-build 4-bedroom, with rents that produce caps in the 1.88%-2.35% range — Texas-tax-burdened, HOA-burdened, and tight-margin. The thesis here is appreciation and tenant quality, not cash flow. The North Side school districts (NEISD, NISD, Comal ISD up the highway) attract the relocating professional families who will pay rent on time and stay three or more years. If you have to choose between a 3.13% cap inside Loop 410 and a 2.19% cap in Stone Oak, the right answer depends entirely on whether you want to be a landlord or you want to be a long-term wealth builder; San Antonio offers both flavors of deal in a way few cities its size do.
Just south of downtown, the historic neighborhoods of King William and Southtown went through their own gentrification arc starting in the early 2000s. Today King William is small, expensive, dominated by 1880s Victorians on lots most of the city has lost, and rarely produces a workable rental deal — the price-to-rent has compressed past investor logic. Southtown proper has more inventory, attracts a young professional and creative-class tenant who works downtown or at the Pearl District north of downtown, and can occasionally produce a duplex or fourplex deal that pencils. The Pearl-adjacent neighborhoods (Tobin Hill, Government Hill on the east side of 281) are where the most interesting infill investing is happening right now: smaller historic homes, growing density of restaurants and breweries, and the long-term tailwind of the VIA Centro Plaza transit improvements. These are appreciation bets on neighborhoods finally consolidating after twenty years of patchy growth.
The city's renter base sorts into four reasonably distinct groups, and matching property to group is most of the underwriting. Military families dominate the Northeast and parts of the Northwest, want fenced yards for kids and pets, will pay BAH-equivalent rents, and rotate every couple of years. Healthcare workers anchor the South Texas Medical Center area on the Northwest side — UT Health, University Hospital, Methodist, and dozens of clinics employ tens of thousands and produce nurses, techs, and administrative staff who want sub-15-minute commutes. The civilian working class, including USAA, H-E-B, Toyota Manufacturing in the south, and Frost Bank, occupies most of the city's middle housing market and rents in the $1,182-$1,529 range citywide. Then there is the student renter near UTSA's Main Campus and around Trinity University and St. Mary's — smaller pool than Austin or Dallas, but real and underserved by purpose-built housing. Median household income across the metro sits near $55,400, lower than Austin or Dallas, which is why the rent ceiling is genuinely lower and your underwriting has to respect it.
Most national investor coverage of San Antonio still treats it as a sleepy military town. That is increasingly wrong. The Toyota Tundra plant on the South Side has been there since 2006 and employs roughly 3,200 directly, with thousands more at supplier facilities. More recently, Microsoft has been building out a multi-billion-dollar data center campus in West Bexar County. JCB has plant operations here. Navistar opened a heavy-truck plant on the South Side in 2022. None of this individually changes the city, but cumulatively it is shifting the southern half of San Antonio from cheap-tract-housing equilibrium to actual industrial-job-driven rental demand. The investors who got into Southside zip codes between 2018 and 2022 at sub-$165,000 prices are now sitting on properties at $220,000 that rent at premiums to what they underwrote. The same dynamic is plausibly available in 2026 in zips that have not caught up yet.
Take a 1980s-vintage 3-bed, 2-bath, 1,400-square-foot SFR in a Northeast San Antonio neighborhood near Randolph AFB, asking $233,750. Market rent comes in at $1,460 — slightly above the city median because of the military-tenant premium. Texas property taxes are the dragon: assume 2.4% of value blended (school district plus city plus county plus MUD), or about $5,610 per year. Insurance on a Texas SFR is $2,200-$2,800 thanks to hail and wind exposure. Run vacancy at 7.48% (military turnover is real even with strong demand), management at 9%, and capex at 7% on a forty-year-old roof you will be replacing within five years. The NOI lands near $8,185 on a purchase price below median, producing a cap rate near 3.13%. With a 25%-down DSCR loan at 7.30%, this deal cash flows positive month one, which is not something you can say for the same archetype in Austin.
Texas has no state income tax. Everyone knows this. What out-of-state buyers consistently fail to model is that Texas funds its state primarily through property taxes, and Bexar County's effective rate plus the various ISD, MUD, and city overlays land in the 2.2%-2.7% range on most San Antonio properties — and ESC-adjusted appraisals reset to market value every year, with rapid catch-up after a sale. A property bought at $275,000 can see its taxable value rise 10% (the Texas homestead-cap doesn't apply to non-owner-occupied investment properties) every single year for five to seven years until the appraisal catches up to actual market value. If you buy in 2026 at today's prices and underwrite at today's tax bill, you are missing a $1-$1 per-year tax escalation that will materialize over the first three years of ownership. Always model property taxes as a percentage of purchase price (2.4% in Bexar is a safe starting point), not as the previous owner's tax bill.
San Antonio sits in a flash-flood-prone region — the city is famously the home of the "100-year flood" euphemism, and certain creeks and arroyos in zips like 78228, 78237, and parts of the South Side have repeating flood histories. Always pull the FEMA map and the Bexar County Flood Control GIS layer before you bid. Hail is the second insurance driver: spring hailstorms regularly produce roof claims across the metro, and insurance carriers have responded by raising deductibles and excluding cosmetic damage on older roofs. Wildfire is not the issue it is in California, but the Hill Country edge of the metro (parts of NW Bexar and Comal County) has growing brush-fire exposure as development pushes into wildland-urban interface. Foundation issues from expansive clay soil are nearly universal — almost every pre-1990 home in the city has some pier-and-beam settling or slab cracking, and a $6,000-$12,000 foundation repair budget should be in your reserve calculation, not a surprise.
The most thoughtful local money I follow is doing three things. First, accumulating SFRs in the South Side zip codes (78211, 78214, 78221, 78224) ahead of the Microsoft data center build-out and the continued Toyota supplier ecosystem expansion — these are currently sub-$206,250 markets where the BAH spillover from Lackland and the new industrial jobs are not yet fully priced in. Second, buying small multifamily near the Medical Center as the corridor continues to densify; 6-12 unit buildings in that submarket trade at 3.29% caps with strong tenant demand. Third, deliberately avoiding Stone Oak and the far north — not because those areas are bad, but because the price-per-door has compressed to a level where the same capital deployed inside Loop 410 produces more total return when you stack appreciation, cash flow, and tax depreciation. The contrarian trade in San Antonio right now is to ignore the new construction and buy the established city.
San Antonio is the Texas market for investors who want Texas demographics, Texas no-state-income-tax tailwinds, and a population that is genuinely growing — without paying Austin or Dallas prices. The cap rates around 3.13% are real and achievable, the military floor is structurally durable, and the South Side industrial story is still in the early innings. The risks are unglamorous: property taxes that escalate aggressively, an insurance market that is tightening on hail, foundation issues on every older home, and a slower-appreciation profile than the headline Texas cities. None of those should disqualify the market for a long-hold investor; they should shape how you underwrite. If you want a Texas market that produces actual month-one positive cash flow on conventional financing in 2026, San Antonio is more often the answer than its three louder cousins.
