Looking for affordable real estate opportunities in San Antonio, TX? This analysis dives into ZIP code insights to uncover areas where median home values fall below the city’s average, offering potential for strong investment returns or accessible homeownership. Using data from 2013 to 2023, we’ve identified the most budget-friendly ZIP codes within a 10-mile radius of the anchor ZIP 78201, providing a clear starting point for investors and agents.
We analyzed American Community Survey (ACS)-style time series data from 2013 to 2023 to ensure a comprehensive view of housing trends. The affordability threshold was set at approximately $210,000, calculated as the average of median home values across all San Antonio ZIP codes for all available years. Each ZIP’s 2023 median home value was compared against this baseline to rank affordability, and we’ve included median gross rent data for additional context on local rental markets. ZIP codes with missing 2023 home value data were excluded to maintain accuracy.
Among the standout ZIP codes, 78207 emerges as the most affordable with a 2023 median home value of $93,200—well below the city’s baseline.
