How Much Income Do You Need to Buy a Home in San Antonio, Texas?

Educational estimate, not a lending decision. Last updated July 15, 2026.

Direct Answer

At the Bexar County median sale price of about $295,000, with 10% down and a 6.49% mortgage rate, you need roughly $107,000 a year to buy at a conservative 28% housing ratio. If you stretch to higher debt-to-income limits, that number drops to about $83,000 at a moderate 36% ceiling and about $67,000 at a maximum illustrative 45% ceiling. The median sale price of a home in Bexar County was $294K over the last 3 months, down 0.3% since the same period last year, according to Redfin.

This is an estimate, not a mortgage approval. No salary guarantees that a lender will approve your loan, and every income figure here is a planning number rather than an underwriting decision.

The rate we use comes from Freddie Mac’s weekly rate survey, a government-sponsored enterprise that tracks mortgage costs. The 30-year fixed-rate mortgage averaged 6.49% as of July 9, 2026, up from last week when it averaged 6.43%. A year ago at this time, the 30-year FRM averaged 6.72%. We assume a 30-year fixed conventional loan with zero discount points every time we use this rate. Your real number depends on your full financial picture: credit profile, existing debts, loan program, down payment, interest rate, property taxes, insurance, HOA charges, assets and reserves, lender underwriting, and income stability and documentation.

Income Needed for the Representative Home Price

We use a “representative home price” of $295,000, which is the current Bexar County median rounded from Redfin’s figure. The median is the middle price, where half of homes cost more and half cost less. This gives you a realistic anchor before you shop.

At that price with 10% down, your estimated monthly housing payment is about $2,503. To keep that at a conservative 28% of your gross monthly income, you need about $107,000 a year. Gross income means your pay before taxes and deductions.

That $107,000 is an estimate, not an approval. It shifts with your credit profile, existing debts, loan program, down payment, interest rate, property taxes, insurance, HOA charges, assets and reserves, lender underwriting, and income stability and documentation.

San Antonio stays cheaper than nearby metros on this math. Compare the income needed in Austin, where higher home prices push the required salary well above San Antonio’s.

Local sources back up this price range. The Bexar County housing market presents a balanced entry point, with the median listing price at $290K, close to the Redfin figure we use.

Local Affordability Calculator

An affordability calculator turns a home price into the income you need, or an income into the price you can target. Most national calculators mislead San Antonio buyers because they under-count two local costs: Bexar County property taxes and Texas homeowners insurance.

Key point: Override the defaults. Set the property tax rate to about 2.1% and annual insurance to about $2,400 so the estimate reflects real San Antonio costs.

A calculator gives you an estimate, never an offer or a locked price. For a number a lender will stand behind, get pre-approved with District Lending, our lending partner, before you shop. Pre-approval means a lender reviews your finances and commits to a loan amount in writing.

Monthly Payment Breakdown

Your monthly payment has more parts than the loan itself. Lenders call the core four “PITI,” which stands for principal, interest, taxes, and insurance. Principal pays down what you borrowed, and interest is the cost of borrowing it.

Two more items can apply. PMI (private mortgage insurance) protects the lender when you put down less than 20%, and HOA (homeowners association) dues cover shared community upkeep where they apply.

Here is the representative $295,000 home with 10% down, using our shared assumptions. Insurance figures like this trace to Texas Department of Insurance data, which reports an average annual premium of $3,506 (Homeowners – 2025 preliminary figure) statewide; we use a lower $2,400 for a representative San Antonio home.

Educational estimate, not a lending decision.

Every line above is an estimate. Your real payment moves with your credit profile, existing debts, loan program, down payment, interest rate, property taxes, insurance, HOA charges, assets and reserves, lender underwriting, and income stability and documentation.

Required Income at 3%, 5%, 10% and 20% Down

Your down payment changes both your loan size and your PMI, so it moves the income you need. Here is the representative $295,000 home across four down-payment levels at a conservative 28% housing ratio.

Educational estimate, not a lending decision.

Key point: PMI shrinks as your down payment grows and disappears at 20% down. That is why the 20% row needs about $94,559 while the 3% row needs about $117,328.

A smaller down payment is not out of reach. Read up on low-down-payment loan options from the Consumer Financial Protection Bureau if saving 20% feels far off. These figures are estimates, not approvals, and depend on the full underwriting-factors list above.

Starter, Representative, and Higher-Priced Home Scenarios

Different price tiers point you toward different parts of San Antonio. Here are three tiers at 10% down and a conservative 28% ratio.

Educational estimate, not a lending decision.

The starter tier near $250,000 tends to sit on the South and East Sides. The representative tier near $295,000 covers areas like Converse and the Northeast. The higher-priced tier near $400,000 reaches suburbs like Stone Oak and Alamo Ranch.

Each required-income figure is an estimate, not an approval, and moves with your credit profile, existing debts, loan program, down payment, interest rate, property taxes, insurance, HOA charges, assets and reserves, lender underwriting, and income stability and documentation.

How Interest Rates Affect the Required Income

The mortgage rate changes your monthly payment, which changes the income you need. All figures below use a 30-year fixed conventional loan with zero discount points, on the representative $295,000 home with 10% down at a 28% ratio. The 6.49% benchmark comes from Freddie Mac’s weekly survey for the week of July 9, 2026.

Educational estimate, not a lending decision.

Key point: A one-point rate move changes the required income by roughly $7,000 to $7,600 per year on this home. A lower rate lets a smaller salary carry the same house.

These are estimates, not approvals. Your actual rate depends on your credit profile and the other underwriting factors, not on a survey average.

How Property Taxes, Insurance, and HOA Fees Affect Affordability

Three local costs push San Antonio’s real number above what national calculators show. Property tax comes first, because Bexar County rates run higher than much of the country.

We apply a 2.1% effective annual tax rate to the home price. Owner-occupants can lower that bill with the Texas homestead exemption. Tax Code Section 11.13(b) requires school districts to provide a $140,000 exemption on a residence homestead, according to the Texas Comptroller.

Insurance is the second cost. We use $2,400 a year for a representative San Antonio home, reflecting local hail, wind, and flash-flooding risk. Flood coverage is separate from a standard policy and comes through the National Flood Insurance Program.

HOA dues are the third cost, and they vary widely. Many older San Antonio homes have none, while master-planned communities like Stone Oak or Alamo Ranch can run $30 to $150 a month. Add that figure where it applies, because it counts toward the payment lenders measure.

How Existing Debt Changes the Estimate

Lenders look at two ratios. The front-end (housing) ratio measures your housing payment against income, and the back-end (total debt) ratio adds your other monthly debts like car loans and credit cards.

Existing debt raises the income you need, because it eats into the same monthly budget. Here is the representative $295,000 home with 10% down, comparing no other debt against $500 a month of debt like an auto loan.

Educational estimate, not a lending decision.

To show the full range, here is the same home across all three debt-to-income (DTI) ceilings with no other debt. DTI is the share of your gross income that goes to debt.

Educational estimate, not a lending decision.

Key point: Adding $500 a month of debt raises the required income by roughly $13,000 to $17,000 a year, depending on the DTI ceiling. Paying down a car loan before you buy can move your number more than you expect.

Upfront Cash Needed

Qualifying income is one thing, and cash to close is another. Upfront cash is your down payment plus closing costs, the fees a lender and title company charge to finalize the loan.

Here is the representative $295,000 home with closing costs at 3% of the price. This traces to typical Texas closing costs; according to Herring Bank, closing costs for buyers in Texas are 2% to 5% of the purchase price, and we use 3% as a mid-range assumption.

Educational estimate, not a lending decision.

TurboHome charges a flat fee instead of taking the full 3% buyer-agent commission, and the difference comes back to you. On this $295,000 home, a 3% commission of $8,850 minus TurboHome’s $6,000 flat fee leaves about $2,850 credited at closing. At 10% down, that drops the cash you bring from about $38,350 to about $35,500.

Key point: The TurboHome rebate reduces the cash needed to close only. It does not change your qualifying income, your debt-to-income ratios, or your approval odds.

Local First-Time Buyer Programs

San Antonio and Texas offer help with the down payment, which is often the biggest hurdle. These programs can lower the cash you need, though each has its own income and property rules.

The City Homeownership Incentive Program (HIP) offers $1,000 to $30,000 in down-payment help as a 0% forgivable loan for buyers at or below 80% of area median income, inside city limits. TSAHC (the Texas State Affordable Housing Corporation) offers up to 5% in down-payment assistance, and TDHCA runs the My First Texas Home program. Buyers near Joint Base San Antonio should also check VA loan eligibility, which can allow a purchase with no down payment.

For context, Bexar County median household income was $72,341 in 2024 dollars over 2020-2024, according to Census QuickFacts. That is context only and never a qualifying threshold; lenders judge your file, not the county average.

How TurboHome May Improve the Buyer’s Position

TurboHome is a flat-fee brokerage that credits most of the buyer commission back to you through our rebate. Here is how that can help, with clear limits on what it does and does not do.

First, the San Antonio buyer rebate puts cash back at closing, about $2,850 on this $295,000 home, which is the 3% commission of $8,850 minus our $6,000 flat fee. Second, the TurboHome Cash Advantage can help you make a stronger offer in a competitive market. Third, you can put a rebate toward a 2-1 buydown, which lowers your interest rate for the first two years and reduces the payment during that time.

A lower payment can lower the income you need at a given DTI ceiling, so the buydown touches the affordability math in a real way.

Key point: The rebate affects your upfront cash. A buydown affects your monthly payment. Neither one changes your qualifying income on its own or guarantees loan approval, which stays with the lender’s underwriting.

What the Typical Calculation Leaves Out

The tables above cover PITI, PMI, and HOA, but real ownership costs more. Budgeting for these extras keeps a tight approval from turning into a monthly squeeze.

• Maintenance and repairs: routine upkeep and surprise fixes like a water heater or roof.
• Utilities: electricity through CPS Energy, plus water, gas, and trash.
• HOA increases and special assessments: dues can rise, and a community can bill a one-time charge for big projects.
• Flood and hazard insurance: flood coverage is a separate policy, and hazard add-ons cost extra.
• Moving expenses and furnishings: movers, deposits, and filling empty rooms.
• Emergency reserves: savings that cover several months of payments if income dips.

These costs do not appear on a qualifying calculator, yet they hit your budget every month. Plan for them before you buy.
