San Antonio 4plexes: Buy a Fourplex and House Hack in San Antonio
San Antonio keeps growing — roughly 1,548,422 people as of July 2025 — and it pairs that growth with the lowest typical home value among the three big Texas cities in this batch, $244,623. Median household income is $66,176, and the rent-to-price relationship here is among the more forgiving in this group, which is why the city belongs on any Texas fourplex short list.
San Antonio by the Numbers
About 37.7% of San Antonio households earn under $50,000, while 31.1% sit in the $50,000–$99,999 band, a mix shaped by the city's large military presence at Joint Base San Antonio, its hospitality workforce, and its health-care employers. Median earnings of $37,315 for all workers tell you that single-earner households will find the typical home value a stretch — which is exactly why rental demand in the city's older, central neighborhoods stays steady.

| Households earning $100,000 to $199,999 (ACS 2024 1-year, B19001) | 23.0% |
| Households earning $200,000 or more (ACS 2024 1-year, B19001) | 8.2% |
| Median gross rent (ACS 2024 1-year, B25064) | $1,389 per month |
| Median earnings, all workers 16 and older (ACS 2024 1-year, B20017) | $37,315 |
| Typical home value (ZHVI, September 2026) | $244,623 |
Annualize the median rent and the picture sharpens: $1,389 a month becomes $16,668 a year, which is 6.81% of the $244,623 typical home value. That percentage is a rough gauge for comparing rent levels with prices, not a return figure — a vacant month, a roof repair, or a tax bill all come out of it before you see a dollar.

Buying a 4plex in San Antonio
Look first at the central neighborhoods around downtown, the Pearl, and the near Westside and Southside, where small multifamily buildings are common and where tenants include military families, medical workers, and service staff. Tourism around the River Walk and the Alamo supports short-stay demand in some pockets, but a house hack should pencil on long-term rents, not on nightly rates — treat any short-term premium as upside, never as the plan. At $244,623 typical value and $1,389 median gross rent, the city-level math is workable; the building-level math, especially property taxes and insurance, still decides it.
Get the leases before you get excited. A rent roll summary can hide a month-to-month tenant, a below-market long lease, or a unit rented to a relative; the signed leases show what each unit truly pays. Compare those real rents with the $1,389 city median, and if the building needs above-median rents on every unit to work, price it lower or pass.
Buyer Help and Loans in San Antonio
Start with lenders who close 2-4 unit deals regularly, and ask them directly about overlays: the extra credit, reserve, or condition requirements they add on top of program minimums for a fourplex in Texas. Two lenders offering the same program can quote very different outcomes once overlays are counted, so the Loan Types page is your checklist for that conversation, not a substitute for it.
Once you have a lender who knows fourplexes, ask for a side-by-side comparison of FHA, conventional, and VA (if you are eligible) on the same San Antonio property, with the same down payment and the same rent assumptions. The Loan Types page explains the programs, including the 5% minimum down on 2-4 unit conventional and HomeReady/Home Possible purchases — the comparison shows which one actually costs least for you.
Living in San Antonio
The San Antonio River Walk at night, its walkways and lights reflected in the water.
The River Walk, the San Antonio Missions, and Market Square give the city a walkable, historic core that few Texas cities can match, and the Pearl district's farmers market and restaurants make weekend life easy for an owner living on site. Summer heat is the trade-off: check any older fourplex's cooling system and insulation before you assume the utility bills in the seller's numbers.
The owners who do best in San Antonio tend to be the boring ones: they buy at a price the rents support, fix small problems before they grow, and keep good tenants with fair treatment and prompt repairs. A fourplex is a long game, and the first year is mostly about learning the building.
