What Credit Score Do You Need to Buy a House in San Antonio? (2026 Bilingual Buyer's Guide)

“Bel, my score isn't perfect — can I even buy a house?” I hear that question almost every week, and the honest answer is usually yes, more often than people expect. As a bilingual (English/Spanish) San Antonio Realtor, I have walked buyers with scores in the high-500s all the way to closing day. The truth is that your number matters, but it is only one piece of the picture.

This guide explains, in plain language, what credit score you need to buy a house in San Antonio in 2026, what changed when Fannie Mae dropped its hard 620 rule, how to buy without a Social Security number, and what a low score actually costs you each month. Whether you are a first-time buyer, an ITIN buyer, or just getting started, my goal is to make this feel clear and doable.

The short answer: what credit score you need to buy a house in San Antonio (by loan type)

The minimum credit score to buy a house in San Antonio ranges from about 500 to 640 depending on the loan. Per the FHA, a 580 FICO unlocks 3.5% down, while the VA sets no minimum at all. Conventional rules loosened in late 2025, so the old 620 floor is no longer absolute.

Here is the part most buyers miss: the government program is only the starting line. Lenders add their own rules, called overlays, on top of those minimums. Two lenders can look at the identical 580 score and give you two different answers. That is why shopping more than one lender genuinely changes what you can afford. Your bilingual Realtor in San Antonio can point you toward lenders who actually serve your score band.

So treat the numbers below as floors, not promises. We will break down each loan type next, then look at what your score does to your monthly payment.

Credit score by loan type: FHA (580/500), Conventional, and VA (no minimum)

By loan type, the published minimums are clear. The HUD Handbook 4000.1 sets FHA at 580 for 3.5% down and 500–579 for 10% down. The VA mandates no minimum score, and Fannie Mae's conventional manual-underwriting floor is 620. The table below puts them side by side.

Sources: HUD Single Family Housing Policy Handbook 4000.1; Fannie Mae Selling Guide B3-5.1-01; Veterans United (VA lender minimums); LendingTree (USDA guidance). Lenders commonly require higher than these floors.

One quick note for military buyers and JBSA families: the VA's no-minimum rule sounds generous, but the lender still sets the bar. Most San Antonio VA lenders land near 620. If your score is lower, a VA loan is still possible, you just need a lender who works that range.

What changed in 2025: Fannie Mae dropped the hard 620 cutoff (and what that really means)

The biggest 2026 shift is that conventional loans no longer require a hard 620 minimum on automated files. Per Fannie Mae Selling Guide Announcement SEL-2025-09, effective November 16, 2025, Desktop Underwriter now evaluates a borrower's full risk profile instead of one cutoff number. That opens the door for some sub-620 conventional approvals.

Here is what that change does not mean. The 620 minimum still applies to manually underwritten conventional loans, and individual lenders can keep their own stricter overlays. So a 610 score might sail through one lender's automated system and get declined at the next. Think of the rule change as a wider door, not an open one.

In my experience, this matters most for buyers who are close to the line. If you were told "come back when you hit 620," it is worth a fresh conversation with a lender who runs Desktop Underwriter. Sometimes the system says yes when an old rule of thumb said no.

Buying with no Social Security number: ITIN home loans in San Antonio explained

You can buy a home in San Antonio without a Social Security number. ITIN loans let you qualify using an IRS Individual Taxpayer Identification Number instead, and per Griffin Funding, they often accept alternative credit such as on-time rent and utility payments. These are typically non-QM or portfolio products.

Because ITIN loans are held in a lender's own portfolio, they usually carry higher rates and larger down payments than FHA or conventional loans. That is the trade-off. The upside is real, though: an ITIN loan can be the bridge to homeownership for buyers who file taxes faithfully but have no SSN, and it can help lengthen a thin credit history over time.

This is an area where working with a true Spanish-speaking Realtor in San Antonio matters. I work with bilingual lenders who handle ITIN files regularly, so nothing gets lost in translation. For a deeper walkthrough, read my full ITIN home loans in San Antonio guide.

No credit score or thin credit? How alternative credit (rent, utilities, phone) works

No credit score is not the same as bad credit, and many loan programs treat it differently. As Griffin Funding notes for ITIN and non-QM products, lenders can build a credit picture from alternative tradelines: on-time rent, utility bills, phone payments, and other recurring obligations. That helps first-generation and immigrant buyers who simply never built a traditional file.

So what counts? Typically a lender wants to see twelve months of clean, documented payments. Rent verified through a property manager or canceled checks is the strongest. Utilities, auto insurance, and phone bills round out the file. The cleaner and more consistent the history, the stronger your application.

One practical tip I share often: start documenting now, even if you are months from buying. Pay rent by check or app, keep statements, and avoid late utility payments. By the time we sit down with a lender, you will have a real track record to show, which is far better than starting from scratch.

San Antonio down payment help and the credit scores they require (TDHCA and assistance)

Down payment assistance can shrink your cash to close, and most Texas programs set their own score floors. Per the TDHCA Texas Homebuyer Program, My First Texas Home and My Choice Texas Home typically require a 620–640 minimum credit score (640 for FHA, VA, and USDA loans), with below-market 30-year fixed rates.

Two things make these programs especially useful here. First, TDHCA adds no extra overlays on immigration status; loans simply follow FHA, VA, USDA, or Fannie Mae rules for non-citizen applicants, including DACA guidance. Second, the Texas Mortgage Credit Certificate (MCC) gives eligible first-time buyers a dollar-for-dollar federal tax credit on part of their annual mortgage interest, which can free up income to help you qualify.

Because these programs stack with FHA and conventional financing, the credit-score math we discussed still applies. I keep a running list of what each program needs. For the full breakdown, see my down payment assistance in San Antonio guide, then we can match a program to your numbers.

What a lower credit score actually costs you per month in San Antonio

A lower score quietly raises your payment for the entire life of the loan. According to Experian data sourced from Curinos LLC, on a $350,000 30-year loan a 620-tier borrower pays about $1,903 per month versus about $1,755 at 760+ — a gap of roughly $148 every single month.

That difference comes from your rate. The table below shows how the average 30-year conventional APR shifts across FICO tiers, and rates generally reach their lowest point (the plateau) once you hit 760 or above. The CFPB confirms lenders typically pull all three bureau scores and use the middle one to price your loan.

Source: Experian, “Average Mortgage Rates by Credit Score,” data via Curinos LLC, based on a $350,000 loan (as of 2026-05-31). Rates change daily; treat these as illustrative.

Put that $148 monthly gap in San Antonio context. With the area median sales price at $307,000 in April 2026 per SABOR data reported by Texas Public Radio, raising your score before you buy can save you real money on a typical local home. You can also model your own numbers with the CFPB Explore Interest Rates tool.

How to raise your score fast: a realistic 3–6 month plan before you buy

You can move your score meaningfully in three to six months without gimmicks. Since the CFPB confirms higher scores earn lower rates, even a 20-to-40-point bump can drop you into a better pricing tier. Here is the practical plan I walk San Antonio buyers through before we shop for a home.

• Pay down revolving balances first. Getting each credit card under 30% (ideally under 10%) of its limit is usually the fastest single lever.
• Never miss a payment. Payment history is the heaviest factor. Set autopay on minimums so one busy month does not undo your progress.
• Do not close old accounts. Length of history helps you. Keep that ancient first card open, even if you barely use it.
• Dispute real errors. Pull your free reports and challenge anything inaccurate; corrections can lift a score quickly.
• Avoid new debt before applying. Hold off on financing a car or furniture until after closing.

Quick reality check: there is no overnight fix, and anyone promising one is a red flag. But steady, boring habits work. If you want a numbers-first look at timing the whole purchase, my rent vs. buy planning guide pairs well with this plan.

First-generation and bilingual buyers: questions nobody answers (en español)

First-generation buyers carry questions that rarely get answered out loud, often in Spanish at the kitchen table. San Antonio is a majority-Hispanic city per the U.S. Census Bureau, yet much of the credit and mortgage system is explained only in English. That gap is exactly where a bicultural agent earns her keep.

The questions I hear most? Can family gift money count toward my down payment? Yes, with a documented gift letter. Does my spouse's lower score drag down our application? Sometimes lenders use the lower of two middle scores, so it is worth structuring the loan carefully. Will applying for credit hurt my immigration case? Buying a home is not a public-charge issue, but I always encourage clients to consult an immigration attorney for legal questions.

None of this is about cutting corners. It is about understanding the rules clearly enough to use them in your favor. When I explain a gift-fund letter or a co-borrower strategy in the language you think in, the whole process stops feeling like a maze.

Realtor or lender first? Your next step when your credit isn't ready yet

Talk to a Realtor and a lender together, early, even before your credit feels ready. There is no rule that says you must wait. Since the CFPB stresses that score and loan type drive your rate, the sooner you start, the more time you have to improve your position before you make an offer in a $307,000 median market.

So which comes first? In practice, start with a quick conversation with me. I will look at your goals, then connect you with a lender who fits your score band and pulls your actual credit. That free pull tells us your real starting point. From there we build a plan, whether you are ready to shop this month or in six months. My first-time home buyer guide lays out the full timeline.
