If you're buying your first home in San Antonio, you're in one of the most affordable major metros in the country — but also one with property tax quirks, neighborhood tax-rate variance, and several first-time-buyer assistance programs most people don't know exist. This guide is the start-to-finish walkthrough I give my own first-time clients, including the down payment programs, loan types, and the actual 12 steps from offer to keys.
I'm Veronica Casias, a residential realtor with Real Broker in San Antonio. I work with first-time buyers every month, and the same questions come up every time. The sections below are organized in the order they tend to come up — start with money, then loan type, then process, then the things that surprise people.
Why San Antonio is a strong first-time-buyer market in 2026
The math is friendlier here than in most Sun Belt cities:
Median home price: Around $295K — roughly $180K below Austin and well below Dallas-Fort Worth.
Cost of living: About 9% below the U.S. average.
No state income tax in Texas, so more of your paycheck applies to your housing payment.
Inventory is up. Active listings rose 15–18% year over year, which means more selection and more negotiating leverage than buyers had two years ago.
The trade-off is property taxes. Texas runs no state income tax but compensates with higher property tax rates than most states. Combined effective rates in San Antonio land between 2.0% and 2.9% of property value depending on the school district and special districts. That matters because your monthly payment isn't just principal and interest — it includes 1/12 of your annual tax bill, every month.
The four financial things you need before you start looking
1. Credit score of 620+
Most first-time-buyer programs in Texas require a 620 credit score. FHA technically allows lower with 10% down, but you'll have far better options at 620+. If you're below that, fix it first — even 30 days of focused work can move the number meaningfully.
2. Two months of bank statements showing stability
Lenders look at deposits to make sure your down payment isn't a recently-borrowed loan. Big deposits need a "source of funds" letter. If a parent is gifting you money, document it formally with a gift letter.
3. Two years of consistent income
Same employer is ideal but not required. Job changes within the same field are fine. Career changes or recent self-employment are harder — you may need two years of tax returns showing the new income.
4. A pre-approval letter from a lender (not a pre-qualification)
Pre-qualification is a guess. Pre-approval is a real underwriting review. Sellers in San Antonio expect pre-approval letters; pre-qualifications get treated as serious-but-not-yet-real.
Down payment assistance: the programs San Antonio buyers actually use
Five programs cover most situations. Each has its own income cap and rules, and some can be combined.
City of San Antonio HIP 80
For households at or below 80% of Area Median Income (AMI). Up to $30,000 in assistance, structured as a 0% interest forgivable second loan. Live in the home five years (ten years for loans over $15K) and the loan is forgiven. Detailed walkthrough coming in our HIP 80 vs HIP 120 guide.
City of San Antonio HIP 120
For households between 81% and 120% of AMI. Up to $15,000 in down payment / closing cost assistance, also as a 0% interest forgivable second loan.
NHSSA (Neighborhood Housing Services of San Antonio)
Up to $20,000 in assistance for first-time buyers, paid as a second mortgage that you pay down over time.
TSAHC — Homes for Texas Heroes / Home Sweet Texas
Statewide programs from the Texas State Affordable Housing Corporation. Heroes program is for teachers, firefighters, police, EMS, and corrections officers. Home Sweet Texas is for low-to-moderate-income buyers. Assistance ranges from $5,000 to $40,000, often as grants or forgivable loans.
TDHCA "My First Texas Home"
The Texas Department of Housing and Community Affairs program. Bond-financed loans with down payment assistance attached. Often the lowest interest rate option for income-qualifying buyers.
You'll need to take an approved 8-hour homebuyer education course before closing on any of these.
Loan types: which one fits your situation
Conventional loan (3% down)
The default for most buyers with good credit and stable income. 3% down is available for first-time buyers via Fannie Mae's HomeReady or Freddie Mac's Home Possible. PMI required until you reach 20% equity.
FHA loan (3.5% down)
Easier credit qualification (580+) and the most permissive on debt-to-income ratios. The catch is mortgage insurance — it sticks for the life of the loan unless you put 10%+ down. Most San Antonio buyers using FHA refinance to conventional once they hit 20% equity.
VA loan (0% down)
If you're active-duty military, a veteran, or a qualifying spouse, the VA loan is almost always the best deal in San Antonio. Zero down, no PMI, competitive interest rates. JBSA buyers — this is your default.
USDA loan (0% down)
For homes in USDA-designated rural areas. Parts of Bulverde, Boerne, and the far Hill Country qualify. Lots of buyers don't realize their dream home is technically in a USDA zone.
The 12 steps from "I want to buy" to "I have keys"
- Get pre-approved with a lender. Two-week process, totally free.
- Pick a buyer's agent (hi). I represent you, not the seller.
- Define your search — neighborhoods, price range, must-haves vs nice-to-haves.
- Tour homes. Most buyers see 8–15 before writing an offer.
- Write an offer. In San Antonio that's the standard TREC contract — earnest money (typically 1% of purchase price), option fee (typically $100–$300), option period (usually 5–10 days).
- Negotiate. Counter-offers, repairs, closing date, possession.
- Schedule the inspection within the option period. Texas-specific issues like foundation movement and HVAC capacity get scrutinized.
- Negotiate repairs based on inspection.
- Appraisal is ordered by the lender. If it comes in low, we renegotiate or walk.
- Final loan approval ("clear to close").
- Final walkthrough the day of or day before closing.
- Closing at the title company. Sign about 50 documents, get your keys.
Total timeline: 30–45 days from accepted offer to keys, assuming financing is conventional and there are no major surprises.
Five mistakes I see first-time buyers make in San Antonio
1. Underestimating property taxes. Buyers focus on principal + interest and forget that on a $300K home, taxes can add $500–$700 to the monthly payment.
2. Not asking about MUDs and PIDs. Many San Antonio new-construction subdivisions sit inside Municipal Utility Districts or Public Improvement Districts that add significant assessments to the tax bill. Ask before you fall in love.
3. Skipping the inspection on new construction. Yes, even on a brand-new home. Production builders move fast, and Texas inspectors find things on new builds every week.
4. Buying near the top of pre-approval. Just because the lender will approve $400K doesn't mean you should buy at $400K. Property taxes, HOA dues, and rising insurance costs can squeeze the margin fast.
5. Falling in love too early. The first house buyers tour usually feels magical. Wait until you've seen at least five before deciding.
Frequently asked questions
How much do I really need saved up to buy a home in San Antonio?
Plan for 5–6% of the purchase price total — 3% down (conventional) plus 2–3% in closing costs. On a $300K home, that's about $15K–$18K. Down payment assistance can cover most or all of this for income-qualifying buyers.
What credit score do I need to buy a home in San Antonio?
620 is the practical floor for getting a competitive rate. 580 is the technical floor for FHA with 3.5% down. Below 580, focus on credit repair before house-hunting.
Can I buy a home in San Antonio with no money down?
Yes — VA loans (military) and USDA loans (rural areas) both allow 0% down. Some down-payment-assistance programs effectively get you to 0% out-of-pocket on conventional and FHA loans too.
How long does it take to buy a home in San Antonio?
From pre-approval to keys: typically 60–90 days. The actual contract-to-close window after you write an offer is 30–45 days.
