Understanding How Interest Rates Affect Your Home Buying Power in San Antonio, Texas (2026)

LAST UPDATED: NOVEMBER 1, 2026 | BY CHRISTOPHER BEAL, U.S. ARMY VETERAN & REALTOR

Update November 1, 2026: I rewrote this guide around the latest Freddie Mac rate (7.24% for the week of October 29, 2026) and recalculated every payment. I also corrected two errors in the earlier version: VA limits seller concessions to 4 percent of the home's reasonable value, not 6 percent, and a pre-approval does not lock your rate. Rate ranges and appreciation figures I could not source have been removed.

I'm Christopher Beal, a U.S. Army veteran and REALTOR (TREC License #723559), Owner of Veteran Real Estate San Antonio, brokered by eXp Realty. More about me. I'm not a lender or financial advisor; the math below is illustrative so you can check your own numbers with your lender.

What does today's rate do to a San Antonio monthly payment?

The table below is principal and interest only on a 30-year fixed loan. It does not include property taxes, homeowners insurance, HOA dues or mortgage insurance, which in Bexar County can add a meaningful amount to the monthly total. The second column uses the Freddie Mac average; the third shows the same loan one full point lower, so you can see what a rate change is worth.

Illustrative calculation by Christopher Beal, November 1, 2026: standard 360-month amortization, principal and interest only. Rate input: Freddie Mac Primary Mortgage Market Survey, 30-year fixed average of 7.24% as of October 29, 2026. The 6.24% column is the same formula one point lower, not a quoted rate. Your rate, APR and total payment come from your lender's Loan Estimate.

Over the full term the gap compounds: a $400,000 loan at 7.24% carries about $581,000 in total interest if held 30 years, versus about $486,000 at 6.24%. Most buyers sell or refinance well before year 30, so treat that as the upper bound of the difference, not a forecast.

How much house does a fixed monthly budget buy at different rates?

Buying power is the loan your income and debts can carry at a given rate. If you hold the principal-and-interest budget constant and move only the rate, the loan that budget supports changes like this:

Illustrative calculation, same inputs and formula as the table above. Lenders also count taxes, insurance and your other debts when they decide what you qualify for, so your approved amount can be lower.

What changes for a VA buyer near JBSA?

The rate survey above is a conventional-loan benchmark. A VA purchase loan changes the rest of the payment picture in ways that matter more than a headline rate:

• No down payment as long as the sales price is not higher than the appraised value, and no private mortgage insurance (VA.gov, purchase loan page).
• VA does not set your rate. Your lender does, so VA rates differ from lender to lender. Shop at least two.
• No VA minimum credit score, though some lenders set one (VA.gov).
• No VA loan limit with full entitlement. You still need lender approval, and the loan cannot exceed the appraised value or the purchase price, whichever is lower (VA.gov).
• A one-time funding fee unless you are exempt: 2.15% of the loan for first use with less than 5% down. Veterans receiving VA disability compensation are among those exempt (VA.gov). See my VA funding fee guide.

Illustrative example: on a $350,000 purchase with 0% down and the 2.15% funding fee financed, the loan is $357,525. At 7.24% that is about $2,437 a month in principal and interest; at 6.74% it is about $2,317. Those two rates are inputs for comparison only, not quotes. If you are comparing VA against FHA, my VA loan vs FHA loan guide walks through mortgage insurance and cash to close.

Can the seller help with my rate on a VA loan?

Yes, within VA's limits. VA does not limit seller credits for normal closing costs, but it caps seller concessions at 4 percent of the home's reasonable value (the value on the VA Notice of Value). Concessions include things like paying your VA funding fee, paying off your debts or prepaying your hazard insurance (VA.gov, updated October 5, 2026). On a home valued at $350,000, the 4 percent concession cap is $14,000.

Two ways sellers commonly help with the rate:

• Discount points. Points lower your interest rate in exchange for paying more at closing; one point equals 1 percent of the loan amount (CFPB). Ask your lender how much rate each point buys on your specific loan, because it varies.
• Temporary buydowns. A 2-1 buydown lowers the payment for the first two years only; the note rate does not change. VA counts a builder- or seller-paid temporary buydown as a seller concession, inside the same 4 percent cap (VA Home Loans temporary buydowns page, updated January 14, 2026). You should still qualify at the full note rate.

Builders around San Antonio often advertise rate incentives tied to their preferred lender. Compare the full Loan Estimate, including price, points and lender credits, against an outside lender before you accept one. My builder incentives guide covers how to compare those offers.

When should I lock my rate around PCS orders?

A pre-approval tells you what a lender expects to approve; it does not lock a rate. A rate lock is a separate agreement with your lender, and locks are typically available for 30, 45 or 60 days, sometimes longer. Extending a lock can be expensive, and a locked rate can still change if your application changes, for example your loan amount, credit score, verified income or the appraised value (CFPB).

For a PCS buyer, that means timing the lock to the contract, not to the orders. Lock once you are under contract and your lender has a realistic closing date, and choose a lock length that covers it with some margin. If your report date or closing could slip, ask the lender in writing what an extension costs before you lock.

Should I buy now or wait for rates to fall?

There is no single right answer; it depends on how long you will own the home, what you would pay in rent while you wait, where prices go, and what a later refinance would cost. Nobody can promise that rates will fall or that you will qualify to refinance. What you can do is run the numbers for your situation:

Illustrative break-even: if a later refinance on a $400,000 loan dropped the rate from 7.24% to 6.24%, the principal-and-interest saving would be about $266 a month. If that refinance cost an assumed $6,000, it would take about 23 months to recover. Your real costs and savings come from your lender. If you already have a VA loan, VA's Interest Rate Reduction Refinance Loan (IRRRL) is the VA route to a lower rate; my IRRRL guide covers who qualifies.

One more option worth asking about: some VA loans are assumable, and an assumed loan keeps the seller's original rate. See my assumable VA loans guide.

What I do with buyers before they shop

1. Get a full pre-approval (credit, income and debts verified), and ask two lenders for Loan Estimates on the same day for the same loan.
2. Pull your free credit reports at AnnualCreditReport.com and fix errors before you apply.
3. Set a monthly budget that includes taxes, insurance and HOA, not just principal and interest.
4. Decide before you write an offer whether you want seller help as closing-cost credits, points or a temporary buydown, and keep VA's 4 percent concession cap in mind.
5. Line up the lock length with the contract and your report date.
