San Antonio is the one major Texas move where the cost of living goes down rather than up. If you are relocating for retirement, for family, or on military orders, that is the number that matters most.
Housing. Average home prices run roughly $216,000 in San Antonio against $259,000 in Houston, and average rent about $1,496 against $1,549. It is the cheapest of the big four Texas metros to buy into, and the gap widens further in the outer suburbs — Schertz, Cibolo and Converse in particular.
Everyday costs. The broader picture is more striking than housing alone. Cost of living for a single person runs around $2,194 a month in San Antonio against $2,770 in Houston, and for a family of four roughly $4,931 against $7,157. That family-of-four gap is substantial and it is the reason a lot of Houston households make this move without a pay rise attached.
Weather. Noticeably drier. About 33 inches of rain a year against Houston’s 53, and less humidity with it. Summers are still hot — this is still Texas — but the flood exposure that shapes where you can live in Houston is much less of a factor.
Day to day. San Antonio reports a lower crime index, 48.1 against 63.5, and it is an easier city to drive: Loop 410 and 1604 give you real alternatives when the interstate backs up. The economy leans on military, healthcare, tourism and manufacturing rather than energy, so it is less exposed to the oil cycle that moves Houston.
Practical note for the move itself: if you are house-hunting in San Antonio while still living in Houston, your closing dates will not line up neatly. That is what storage in transit is for, and it is cheaper to plan for it than to discover it two weeks out.
