Investing in San Antonio, TX — Market Analysis
San Antonio is one of the lower-basis entry points in Texas, with a median home price around $290,000. As a primary metro, San Antonio gives you the deepest tenant pool in Bexar County — the kind of market where a vacancy is measured in days rather than months, and where lenders are most comfortable with appraiser rent schedules because there are hundreds of comparable leases to draw on.
Buying a rental property in San Antonio on a DSCR loan means putting a minimum of $58,000 down (20% of purchase price), leaving a loan amount of $232,000 at 80% LTV. At current DSCR investor pricing near 7.50%, principal and interest on that loan runs about $1,622 per month. Add Bexar County property taxes of roughly $471/month and landlord insurance of about $116/month, and your all-in PITIA lands near $2,209/month. That PITIA figure — not the P&I — is what the lender divides your rent into.
A long-term lease in San Antonio should generate roughly $1,800/month in gross rent. Against a PITIA of $2,209, that produces an estimated DSCR ratio of 0.81x. That is well below the 1.0 threshold on a long-term lease, which is typical for a market at this price point. Financing here generally works one of three ways — a larger down payment, a no-ratio DSCR product, or qualifying on short-term rental revenue instead of long-term rent.
If you intend to operate the property as a short-term rental, estimated gross nightly revenue in San Antonio is around $2,700/month across a full year. Lenders do not credit gross STR revenue dollar-for-dollar — they typically haircut it 25%–30% for vacancy, cleaning, platform fees, and management. Applying a 28% haircut gives an effective $1,944/month, or a DSCR ratio of 0.88x. Even on short-term revenue this is a tight file, so plan on a larger down payment or a no-ratio structure.
Two Texas-specific items to build into your model: Texas has no state income tax and landlord-friendly eviction timelines, but property tax rates are among the highest in the country — typically 1.8%–2.5% of assessed value, which materially affects DSCR ratios. In San Antonio specifically, effective property tax on investment property runs around 1.95% of value annually — about $5,655 a year at the median price — and landlord insurance near $1,392 a year.
On return metrics, San Antonio pencils to an estimated cap rate of 4.62% using a 62% NOI margin, and a gross rent multiplier of 13.4. Monthly cash flow on a long-term lease at 20% down is estimated at $409 negative. Negative cash flow at 20% down is common in appreciation-led markets; investors here typically increase the down payment, buy below median, add a unit, or run the property short-term to close the gap.
