Two San Antonio-area ZIP Codes were among the 10 hottest for homebuyers last year, according to a study released last week by online real estate marketplace Opendoor. San Antonio’s 78253, home to the West Side’s Alamo Ranch subdivision, landed at No. 9 on the list up two spots from last year’s ranking. Meanwhile, New Braunfels’ 78130 came in at No. 8 spot, dropping four spots from the 2022 study. Opendoor’s rankings were based on which Zip Codes had the most sales within 90 days of listing, on average.
