San Antonio, TX: Rental Property Market Guide

Updated March 2026 · Pop. 1,451,853

San Antonio is a military city first and everything else second. Joint Base San Antonio encompasses three major installations — Fort Sam Houston, Lackland AFB, and Randolph AFB — employing over 80,000 military and civilian workers combined. That's the largest concentration of military personnel in the Department of Defense. Every one of those 80,000 employees receives a Basic Allowance for Housing. For rental investors, this means a tenant pool where the government literally guarantees the housing budget. No other San Antonio economic factor comes close to the military in terms of its impact on the rental market.

The BAH Playbook

2026 BAH rates for San Antonio range from $1,476/month for an E-5 with dependents to $2,190 for an O-4 with dependents. These rates cover the service member's full housing cost — rent plus utilities. The smart investor strategy is to price properties just under the BAH rate for the target rank, so military tenants can pocket the small difference. A 3-bed/2-bath near Lackland AFB (78236, 78245) priced at $1,400/month attracts E-6 and E-7 families whose BAH of $1,600+ covers rent with room to spare. Properties near Fort Sam Houston (78209, 78217) attract medical personnel (Fort Sam is home to the Army's medical training command) at $1,500-1,700/month. The key: properties within a 20-minute drive of a base gate rent in days, not weeks.

The Property Tax Sting

Bexar County's effective property tax rate is 2.2% — brutal on higher-value properties. On a $270K home, that's $5,940/year, or roughly $495/month added to your carrying costs. Texas lets you protest your property tax assessment annually through the Bexar County Appraisal District (bcad.org), and you absolutely should — the success rate on protests in Bexar County is around 50-60%, with an average reduction of 5-10%. There are also property tax protest companies (like Ownwell or O'Connor) that will file on your behalf for 25-35% of the savings — only paying if they win. On a $5,940 tax bill, a 10% reduction saves $594, of which you'd pay $150-200 to the protest company. Worth it every year.

The Northeast Side Growth Corridor

San Antonio's growth has pushed strongly northeast along I-35 toward New Braunfels and along Highway 281 toward Bulverde. Schertz (78154), Cibolo (78108), and Converse (78109) are booming suburbs with strong school districts and new construction. Entry points: $250-320K for a 3-4 bedroom, renting for $1,500-1,800. These areas attract military families from Randolph AFB and professional families working at USAA's headquarters (19,000 employees on the north side). The northeast side has the best combination of tenant quality, school ratings, and rent growth in the metro. Turnover is low because families with school-age kids don't move mid-year.

The South and West Side: Affordable Entry

For cash flow at lower price points, the south side (78214, 78221, 78224) and west side (78228, 78237) near Lackland AFB offer properties at $160-230K with rents of $1,100-1,400. The tenant base is more diverse here — military enlisted, healthcare workers from the South Texas Medical Center, and civilian workers from nearby military support contractors. Cap rates are higher (7-8%) but vacancy and turnover are modestly above the metro average. Properties near Kelly Field (the former Kelly AFB, now Port San Antonio — a growing tech and cybersecurity campus) benefit from the redevelopment, which has brought new employers and investment to an area that was stagnant for years.

San Antonio vs. Austin: The Cost Reality

Austin is 80 miles north and gets all the headlines, but San Antonio's rental math is dramatically better. The same $1,400/month rent that requires a $400K property in Austin requires a $250K property in San Antonio. Your cash-on-cash return in San Antonio is 2-3x what you'd earn in Austin on the same amount of invested capital. Austin offers more appreciation potential, but San Antonio offers actual income — and the military employment base provides stability that Austin's tech-dependent economy can't match. Many Texas investors buy cash-flow properties in San Antonio and use the income to fund down payments on appreciation plays in Austin. It's a barbell strategy that works because the cities are close enough to manage with the same trip.
