ZIP code 78731, in Austin, ranks among the more affluent areas of the city, with a median household income of $105,494 and per-capita income of $94,483. Home values are steep: the median sits at $903,200, and the county-level effective property tax rate of 1.48% means owners face a substantial annual bill.

This is a well-off pocket of Austin where housing costs and taxes both run high.
