The local market
County Business Patterns counts 269 all other specialty trade contractors across the San Antonio-New Braunfels, TX Metro Area, 2.78 for every ten thousand households. That is roughly one for every 3,597 households. The Census counts locations rather than companies, so a one-truck operator and a national chain's branch each count once. The Census has no code of its own for this trade, so the number is the catch-all for specialty trades and overstates the trade itself.
Home prices
The Federal Housing Finance Agency's house price index for San Antonio-New Braunfels, TX is up 0.3% over the latest year (through 2025). Over five years it is up 39.5%, and over ten it is up 83.3%. The index follows repeat sales of the same houses, so it measures how prices moved, not what any one home sells for this month.

The American Community Survey is a sample, so every housing figure carries a margin of error, and it is widest for small areas. Where a source suppresses a cell to protect individual businesses or because the sample is too thin, we leave it blank rather than estimate it.
