Investment Summary
As of 2026, rental properties in San Antonio, TX yield a 5.9% cap rate. Median home price is $245,556 with 3-bedroom rents at $1,845/month.
San Antonio is a moderate market — workable but not exceptional for cash flow. At $245,556 median home price, San Antonio is affordable by national standards and within reach for most conventional loans. With 3-bedroom rents around $1,845/month, the 5.9% cap rate tells the story. At current prices and rates, expect to lose about $118/month — negative cash flow unless you put more down or find below-market deals.
The 1% rule comes in at 0.77% — doesn't quite pass, but close enough to find individual deals that work. DSCR of 0.92 is below 1.0, meaning rental income doesn't cover the mortgage. DSCR lenders will likely decline this market at current prices.
Bottom line: San Antonio offers a balance of moderate cash flow and growth potential. Good for investors who want some income while building equity over time.
