Is San Antonio a Good Place to Invest in Rental Property?

San Antonio, TX has a population of 1,547,253 and has been growing at 1.4% annually — above the national average, suggesting steady demand pressure on housing. The median home price of $280,000 paired with median rents of $1,420/mo produces an estimated cap rate of 3.15%.

Property taxes at 1.72% are notably high and represent a significant drag on cash flow — model this expense carefully, as it can make or break a deal. The vacancy rate of 6.8% is moderate and within normal parameters for a healthy rental market.

At a price-to-income ratio of 5.1x, homes cost about 5.1 times the local median income of $55,400. This moderate ratio indicates a balanced rent-vs-buy market. Home values have appreciated at roughly 2.5% annually. Steady appreciation means total returns will be primarily cash flow-driven — the more sustainable model for long-term wealth building.

Bottom line: At current median prices, San Antonio is challenging for pure cash flow investing. Consider BRRRR strategies with below-market purchases, or look at neighboring metros with stronger price-to-rent ratios.
