Current Market Snapshot
Investment Analysis

The affordability index of 104 indicates housing is accessible for median-income households — a healthy foundation for sustained demand.
Market Temperature: Warm
With a median DOM of 40 days and approximately 5,500 active listings and balanced competition, San Antonio's market is currently classified as warm. Balanced conditions allow time for due diligence and negotiation.
The Numbers on a Median-Priced Rental
Buying the median San Antonio home at $290,000 with 20% down takes $66,700 in cash — a $58,000 deposit plus roughly $8,700 in closing costs at 3% — and leaves a $232,000 loan. At 7.0% over 30 years that is $1,544/month in principal and interest.
On those assumptions the median San Antonio rental produces a 2.49% cap rate and falls roughly $942 a month short of covering debt service. Cash-on-cash return on the $66,700 invested is -16.94%, and the debt service coverage ratio is 0.39× — below 1.0×, meaning the property cannot service its own debt at 20% down — this is an appreciation play, not a cash flow one. On a rent basis, you need $2,538 a month to break even — 78% above the $1,425 HUD benchmark.
Rate and Rent Sensitivity
Financing cost dominates the outcome. One percentage point on the mortgage rate moves monthly cash flow by more than a 10% swing in rent does:
| Mortgage Rate | P+I Payment | Monthly Cash Flow |
|---|---|---|
| 6.0% | $1,391/mo | -$789/mo |
| 7.0% | $1,544/mo | -$942/mo |
| 8.0% | $1,702/mo | -$1,100/mo |
| Rent Scenario | Monthly Rent | Cap Rate | Monthly Cash Flow |
|---|---|---|---|
| HUD FMR − 10% | $1,282/mo | 1.99% | -$1,063/mo |
| HUD FMR | $1,425/mo | 2.49% | -$942/mo |
| HUD FMR + 10% | $1,567/mo | 2.99% | -$822/mo |

What Has to Be True for San Antonio to Work
A median-priced rental here consumes $11,304 a year in cash. That is not automatically a bad deal: the same loan repays $2,357 of principal in year one, so the true first-year drag is about $8,947. To break even on the cash line alone the property has to appreciate 3.9% a year, against the +2.0% the metro has actually posted over the past twelve months. Hold it five years and amortisation alone builds $13,615 of equity — the question is whether you can fund the shortfall for that long without selling at the wrong moment.
