San Antonio at a Glance

San Antonio has developed into a genuinely appealing market for homebuyers, with a median home value around $369,400 and a strong owner-occupancy rate of nearly 76 percent—a sign of neighborhood stability and investment confidence. The median household income of $93,744 reflects a solid middle-to-upper-class foundation, and with 38.5 percent of residents holding bachelor's degrees or higher, you're looking at an educated community that tends to support good schools and civic engagement.

The community itself feels established rather than transient. Three-quarters of people own their homes here, which creates the kind of neighborhood continuity where people actually know their neighbors and maintain their properties. Air quality is excellent right now, sitting at an AQI of 39, so if respiratory health concerns you, that's a real positive.

On the natural hazard side, there are two things to factor into your decision. San Antonio sits in EPA radon Zone 2 (moderate risk), so you'll want to get a radon test done on any property before closing—it's manageable but real. The area also experiences moderate seismic activity, averaging around 24 small earthquakes annually over the past decade, with the largest reaching 4.6 magnitude. These aren't typically damaging, but if earthquake insurance or risk mitigation matters to you, keep that on your radar when evaluating properties.
