San Antonio MSA

San Antonio’s most unaffordable ZIP code—ZIP 78257—has a value-to-income ratio 2.5x higher than the median ZIP in the metro, according to ALEX Intelligence’s latest data. This 2.5x gap reveals a deepening divide in access to homeownership, where only a small subset of residents can afford the most expensive areas. The data shows that affordability is not a regional issue but a ZIP code lottery, with ZIP 78257 leading the metro by this margin.

This isn’t about 'high prices'—it’s about how income is concentrated in specific zones, and how that concentration drives further inequality. What does this mean for zoning, inclusionary zoning, and equity-focused development in the San Antonio MSA?
