San Antonio's 0.5% rent-to-price ratio is well below the 1% rule. At median prices of $275,000, the $1,390/mo rent produces only $718/mo in NOI. Investors here need to target below-median properties or pursue value-add strategies to make the numbers work.
At current rates, a 20% down conventional loan ($55K at 7%) would result in approximately $-745/mo cash flow — negative at median prices. Larger down payments, seller financing, or buying 15–25% below median are strategies to turn the numbers positive.
Property taxes consume 28% of gross rent here — one of the highest ratios in our dataset. This significantly compresses margins and makes San Antonio a market where tax-conscious underwriting is essential. Every deal should be stress-tested with potential assessment increases.

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 $275,000 paired with median rents of $1,390/mo produces an estimated cap rate of 3.13%.
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 5.0x, homes cost about 5.0 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.
