ZIP Code 78257

In ZIP code 78257, on San Antonio's northern edge, homes carry a median value of $670,400 while households earn a median of $81,301. That gap matters: at the county's 1.73% effective rate, property taxes on a median-valued home would run roughly $11,600 a year, a sum that would absorb a substantial share of median household income. Per-capita income reaches $73,622, which eases things somewhat for individual earners, though the ratio of home prices to earnings still shapes who can buy here. Sales tax is 6.25%.
