How Much House Can You Afford on BAH in San Antonio?

What BAH is designed to cover

Basic Allowance for Housing is a nontaxable monthly allowance paid to service members to offset housing costs. The Department of Defense sets the rate by pay grade, dependent status, and location, and publishes the table each December for the following calendar year. The underlying calculation is built from rental market data in each military housing area, so the number tracks what housing actually costs where the member lives, not a fixed rule about what to spend.

When a service member rents, BAH is meant to push most of the rent and utilities toward the allowance line. When a member buys, the same check is available, and it is up to the household how much of the mortgage payment comes from BAH versus base pay. The allowance does not care whether it covers rent or a loan payment; the budget does the sorting.

For members reporting to Joint Base San Antonio, one rate table applies to all four installations. Lackland, Fort Sam Houston, Randolph, and Camp Bullis share the same San Antonio military housing area, so the numbers below are the same regardless of which gate the service member reports to.

The 2026 BAH numbers at Joint Base San Antonio

The 2026 rates for the San Antonio military housing area, effective January 1, 2026, run across pay grades and dependent status. For an E-5, the rate is $1,869 a month with dependents and $1,500 without. For an E-6, it is $2,094 with dependents and $1,596 without. For an O-3, it is $2,127 with dependents and $2,007 without.

The 2026 table came in slightly below 2025 across common pay grades as the rental data behind it moved. One example: E-6 with dependents was $2,154 in 2025 and is $2,094 in 2026. The change is worth knowing when a service member budgeted a move on the prior year's number, because a small shift in the allowance changes the top of the purchase range.

Because the rate is the same for every installation under Joint Base San Antonio, the buying-power exercise below looks identical whether the service member is aiming at a commute to Lackland, Fort Sam Houston, Randolph, or Camp Bullis. The commute and the inventory differ; the allowance does not.

Turning the allowance into a purchase price

The full payment is the number that matters: principal, interest, property taxes, homeowners insurance, and any HOA fee. The 30-year fixed rate averaged 6.95 percent in the Freddie Mac Primary Mortgage Market Survey for the week ending September 17, 2026. At that rate, principal and interest run about $1,986 a month on a $300,000 loan, $1,655 on a $250,000 loan, and $1,324 on a $200,000 loan.

Taxes and insurance sit on top of principal and interest. For the example below, assume $500 a month combined for property taxes, homeowners insurance, and an HOA fee if there is one. That figure is an assumption for illustration, not a quote: Texas tax rates vary by address and insurance varies by policy, so a lender prints the real number. With that assumption, an E-6 with dependents at $2,094 in BAH can put about $1,594 a month toward principal and interest, which buys roughly a $240,000 home at the current rate.

The same math for the other common rates: an O-3 with dependents at $2,127 supports about $245,000, and an E-5 with dependents at $1,869 supports about $205,000. Every line changes with the rate, the tax and insurance figure, and the choice of how much of the payment comes from BAH versus base pay. A lower purchase price, a down payment (VA loans allow zero), a slightly lower rate, or lower taxes and insurance all move the answer up or down.

Where the VA loan changes the math

For buyers with full entitlement, a VA loan finances 100 percent of the purchase at zero down payment, which means the loan amount and the sale price are close to the same number and there is no monthly mortgage insurance premium to budget. The one-time VA funding fee on a first-time use with less than 5 percent down is 2.15 percent of the loan amount, about $6,450 on a $300,000 purchase, and it can be financed into the loan. Veterans receiving VA disability compensation, and certain surviving spouses, are exempt from the fee entirely.

Borrowers with full entitlement have no VA loan limit, so the ceiling is set by underwriting rather than a county cap. The $832,750 baseline limit for 2026 matters only for borrowers with partial entitlement, such as a member whose entitlement is still attached to a prior home. The practical result for a BAH budget: the payment, not the program, sets the price range.

VA underwriting looks at total household income, debts, and residual income after major monthly obligations, with each lender applying its own debt-to-income guideline. A payment that sits inside BAH leaves most of base pay outside the housing calculation, which is exactly the posture that makes a VA file straightforward for a lender.

What that budget buys in today's San Antonio market

The August 2026 SABOR MLS Summary Report, last updated September 7, 2026, put the San Antonio area median single-family sale price at $299,275, with 3,104 closed sales, an average of 82 days on market, and homes selling for an average of 92.8 percent of their original list price. A full BAH budget at current rates lands below that median, which makes the exercise realistic across a wide band of the market.

The $205,000 to $245,000 range is an active part of the San Antonio MLS in both resale and new construction. Eighty-two average days on market means buyers in this range have room to compare homes without being forced by scarcity, while well-priced homes still sell inside a few weeks. The range exists across the market; which side of town has the homes that fit both the budget and the commute is a search question, not a guess.

That is where Tami Price, Broker Owner of Tami Price Properties, starts with every PCS client: the installation, the gate, the commute budget, the payment that fits BAH, and the current inventory inside that band. The allowance sets the payment, the payment sets the price, and the price sets the search, and each step is based on current numbers rather than general impressions of the city.

The steps to test the fit before you commit

First, get a VA preapproval and ask the lender for the full monthly payment at the rate they quote, including taxes and insurance. That single number does more than any price point, because it converts a rate, a price, and local costs into the one figure that has to fit the budget. Second, run the payment against BAH and decide how much of the payment comes from the allowance versus base pay. BAH is nontaxable, so the take-home math differs from civilian pay, and that difference is real money in the monthly picture.

Third, price the search at the payment, not at the price. Two homes at the same price can carry very different tax and insurance loads, and an HOA fee changes the monthly total as surely as a rate change does. Fourth, keep the calendar in mind: with BAH and a VA purchase linked to a PCS report date, a broker who works military moves can plan the preapproval, the house hunting visit, the appraisal, and the closing around the tour.

Tami walks clients through this math in a working session before the search starts, using the current rate, the member's actual BAH, and the real payment from the lender. The numbers do the deciding, and the client walks in knowing what the allowance can and cannot carry in today's San Antonio market.
