Rent vs. Buy in San Antonio: October 2026 Update

This is the monthly rent vs. buy update for Greater San Antonio and the Texas Hill Country: San Antonio, Stone Oak, Alamo Ranch, Boerne, Bulverde, Spring Branch, New Braunfels, Canyon Lake, Schertz, Cibolo, Helotes, Fair Oaks Ranch, and Timberwood Park, across Bexar, Comal, Kendall, and Guadalupe counties. Every number below was researched this month and is linked to its source with its date. Nothing here is a forecast, and the estimates are not a loan offer.

The numbers this month

Side by side, here is the monthly choice: rent a typical home, or buy a median-priced home at this week's rate with a 3.5% down FHA loan.

The estimated buy side is about $830 a month more than the typical rent. Here is exactly what that estimate contains:

Not included: HOA fees, maintenance, FHA's 1.75% upfront mortgage insurance premium, and closing costs. Line items are rounded, so they may not sum exactly. Estimates are not a loan offer. Your actual payment depends on the property, your credit, your rate quote, and your tax and insurance numbers.

Where these numbers come from

Every figure is sourced and dated. The payment estimate is simple arithmetic applied to the two researched inputs, the median price and the rate, under the assumptions listed in the table.

• Median price. SABOR's August 2026 report put the San Antonio-area median sold price at $299,275, unchanged from a year earlier. That is the latest published local report, released September 16, 2026. The SABOR area is centered on Bexar County and includes surrounding counties. Source: Texas Public Radio, September 16, 2026.
• Rate. Freddie Mac's Primary Mortgage Market Survey, released October 1, 2026, put the average 30-year fixed rate at 7.28%, up from 7.03% the prior week and 6.34% a year earlier, the highest reading since November 2023. Sources: Freddie Mac PMMS, October 1, 2026 and the Freddie Mac release, October 1, 2026.
• Rent. RentHop's August 2026 survey listed $1,875 as the average 3-bedroom house rental in San Antonio. Source: RentHop, August 2026. For context, San Antonio Rentals' 2026 market report puts the average single-family rent near $2,002, and Ark7's guide, January 2026, lists $2,018.

What the gap means

Renting is cheaper on paper this month by roughly $830, and that is a real number, not a marketing point. It buys flexibility: a lease ends, you can move, and your upfront cash is a deposit, not a down payment. The trade is that none of that rent builds ownership for you, and your rent can be raised when the lease renews.

The buy side costs more each month because it carries the full cost of ownership: principal, interest, taxes, insurance, and mortgage insurance. Part of your payment, the principal share, builds equity you keep, and a fixed rate locks your principal and interest for 30 years. At 7.28%, the interest share is larger than in the low-rate years, so equity builds more slowly at first.

The old rule still holds: plan to stay in the home for several years, and the longer you stay, the stronger the buy case gets. If you might move within a year or two, for a job, a PCS, or a life change, renting is often the smarter math. With prices flat year over year and rents holding roughly steady, waiting is a defensible choice for someone who is not ready to commit.

Two honest caveats. First, taxes and insurance here are assumptions at 1.7% and 0.7% of price; the real numbers vary by address, and the homestead exemption does not apply to every property. Hill Country addresses in Comal, Kendall, and Guadalupe counties can differ from the Bexar County picture, sometimes a lot. Second, this estimate is FHA-specific; VA buyers skip mortgage insurance entirely and USDA can finance at zero down in eligible areas, so their comparison can look different. Check your own numbers before you decide, and I can help you run them.
