Credit Score to Buy a House in Texas: Minimums by Loan Type

The Score Requirements Map for Texas Home Buyers

Texas buyers have access to every major federal mortgage program, but the gap between published federal minimums and what lenders actually require is significant — often 20–40 points. Understanding the difference between “what FHA allows” and “what your lender will do” prevents wasted application time and the frustration of assuming you qualify for a program that specific lenders won’t originate at your score.

FHA: Published HUD minimum 580 (3.5% down) and 500–579 (10% down). Lender overlay reality: most FHA lenders require 580–600 minimum, working scores in the 580–619 range only through manual underwriting. True 500-tier lending requires seeking community banks, credit unions, or nonprofit HUD-approved lenders who do heavy manual underwriting. Best use case: 580–680 score buyers who need low down payment and whose DTI challenges exceed what conventional accommodates.

VA (Veterans Affairs): No published FICO floor. VA Lender Handbook Chapter 4 specifies no minimum score. Lender overlay reality: 580–620 is the common overlay range; some VA-specialized lenders go below 580 with strong compensating factors (residual income, stable employment, reserves). Best use case: any eligible veteran — VA is financially superior to every other program at virtually every score tier where it’s available.

USDA Section 502 Guaranteed: No USDA-published minimum. Automated approval through the Guaranteed Underwriting System (GUS) is most reliable at 640+. Manual underwriting available below 640 for properties in USDA-eligible areas. Best use case: buyers in USDA-eligible rural and suburban-rural Texas (significant portions of Texas qualify) who want zero down payment without VA eligibility.

Conventional (Fannie Mae/Freddie Mac): Published minimum 620. Automated approval through DU/LPA becomes unreliable below 640; manual conventional underwriting is rare and program-limited. LLPA pricing makes conventional expensive in the 620–680 range. Best use case: 700+ score buyers with 10–20% down who want the lowest long-term mortgage insurance cost structure.

Texas Vet Loan (VLB): Same VA eligibility requirements. VLB-participating lenders offer a below-market rate subsidy (0.25–0.50% below market VA rates) for eligible Texas veterans purchasing in Texas. Score overlay depends on the specific participating lender. Best use case: any eligible Texas veteran purchasing in Texas — stack the VLB rate subsidy on federal VA benefits at whatever score you qualify.

How Texas Property Taxes Interact With Credit Score and DTI

Texas has higher property taxes than the national average — the Tax Foundation’s state data shows Texas’s median effective rate at approximately 1.74% versus the national average of approximately 1.10%. This creates a Texas-specific DTI challenge: the same income and purchase price qualify for a higher loan amount in a low-tax state than in Texas, because the property tax component of the required PITI calculation is higher.

Worked example: $350,000 purchase, $70,000 annual income, no other debts. Texas property tax at 1.9%: $6,650/year = $554/month. Insurance: $3,000/year = $250/month. Principal and interest on $332,500 (5% down) at 7.0%: $2,213/month. Total PITI: $3,017/month. Back-end DTI: $3,017 ÷ ($70,000/12) = 51.7%. That exceeds conventional’s effective 45% approval ceiling at most score tiers, and pushes into the upper range of FHA’s tolerance even with compensating factors.

The same purchase in a 0.75% property tax state: PITI ≈ $2,480/month. DTI ≈ 42.5% — comfortably within conventional automated approval range. Texas buyers earning $70,000/year legitimately qualify for a smaller home or need a higher income to match the qualifying power of equivalent buyers in low-tax states. This isn’t a financing problem — it’s a structural feature of Texas’s tax environment that affects every buyer’s qualifying numbers.

Texas homestead exemption partially offsets this. Filing Form 50-114 with your county appraisal district by April 30 of the year following purchase reduces school district taxable value by $100,000, saving $800–$1,200/year starting in year two. This doesn’t affect your qualifying DTI calculation (lenders use first-year taxes before the exemption takes effect), but does reduce your actual carrying cost from year two onward.

LLPA Grid: The Real Dollar Cost at Each Score Tier

Fannie Mae’s Loan Level Price Adjustment matrix is publicly available at fanniemae.com. For a $300,000 30-year conventional loan with 5% down (95% LTV), the LLPA impact by score tier translates to both upfront cost and effective rate premium:

• 620 FICO: LLPA ≈ 3.25% = $9,750. Rate equivalent ≈ +0.65%. Monthly payment premium vs. 760 score: approximately +$130/month.
• 640 FICO: LLPA ≈ 2.25% = $6,750. Rate equivalent ≈ +0.45%. Monthly premium vs. 760: approximately +$90/month.
• 660 FICO: LLPA ≈ 1.75% = $5,250. Rate equivalent ≈ +0.35%. Monthly premium vs. 760: approximately +$70/month.
• 680 FICO: LLPA ≈ 1.25% = $3,750. Rate equivalent ≈ +0.25%. Monthly premium vs. 760: approximately +$50/month.
• 700 FICO: LLPA ≈ 0.75% = $2,250. Rate equivalent ≈ +0.125%. Monthly premium vs. 760: approximately +$25/month.
• 720 FICO: LLPA ≈ 0.375% = $1,125. Nearly at par.
• 740+ FICO: Minimal LLPA. Par pricing.

These LLPAs explain why FHA frequently produces lower total monthly cost for buyers in the 580–660 range even with MIP: FHA’s flat 0.55% MIP adds approximately $130/month on a $280,000 loan, but FHA doesn’t load $130/month in rate through LLPAs. When the two premiums are directly comparable in magnitude, FHA’s LLPA-free structure produces competitive or better total payment than LLPA-loaded conventional plus PMI.

The Rapid Rescore Tool: Moving Your Score Before Application

If your qualifying score is 10–30 points below a meaningful threshold — 580 for FHA 3.5% down, 620 for conventional, 680 for better conventional pricing — a rapid rescore can close that gap faster than waiting for the normal bureau update cycle.

How it works: you take a legitimate action that should improve your score — pay down a credit card balance, pay off a collection account, correct an error. You provide your lender with documentation proving the change: the current statement showing the new balance, the collection payoff receipt, the creditor’s written correction letter. Your lender submits this documentation to their tri-merge bureau vendor, who updates the bureau record directly. Updated scores return in 3–7 business days rather than the 30–45 days it would take for the normal bureau reporting cycle to carry the change.

Rapid rescore only works on legitimate, documentable changes — it’s not a score manipulation tool, and bureau vendors verify the supporting documentation. But for a borrower who paid off a $1,800 collection account last week and is applying for a mortgage this week, it’s the difference between qualifying now versus waiting 6 weeks for the bureaus to update on their own. Ask your loan officer directly: “If I pay off this collection before application, can we do a rapid rescore to reflect the updated status before my file goes to underwriting?”

Buy Now vs. Improve Score First: The Texas Market Math

The buy-now-versus-wait decision has a real financial answer in Texas, not just a philosophical one. The key variables are Texas market appreciation and the monthly payment savings achievable by improving your score.

Texas major metro appreciation (FHFA HPI 5-year averages): Dallas-Fort Worth approximately 6.8% annually; Austin approximately 5.1%; Houston approximately 4.9%; San Antonio approximately 5.4%. At 5% annual appreciation, a $350,000 home becomes $367,500 in 12 months — $17,500 in appreciation you don’t capture by waiting.

Rate savings from improving 640 to 700 on a $300,000 conventional loan: approximately 0.45% in LLPA reduction, roughly $80/month in payment savings. Break-even on waiting: $17,500 ÷ $80 = 218 months — 18+ years. The appreciation foregone by waiting 12 months to improve your score requires 18 years of monthly savings to recover. In appreciating Texas markets, buying now and refinancing when your score improves consistently outperforms waiting.

The waiting strategy has legitimate merit in only specific circumstances: your score is genuinely below any program minimum (below 500 with no compensating factors), you’re within the mandatory waiting period after a bankruptcy or foreclosure, your DTI is above 57% and no program will approve you, or you have unresolved judgments or liens that must be cleared before any lender can proceed. If you qualify for at least FHA at 580, the financial case for buying now is usually stronger than the case for waiting in Texas’s market environment.

First Steps for Sub-640 Texas Buyers

The most productive sequence for moving from “considering buying” to “qualified and under contract”:

1. Pull all three bureau reports at AnnualCreditReport.com. Map every negative item — late payments, collections, high-utilization accounts, errors. Determine which are disputable (errors, inaccuracies) and which require payment or time.
2. Identify your current middle score across three bureaus. Not the score your bank app shows (usually a FAKO score using a proprietary model) — the actual FICO Score 2, 4, and 5 used by mortgage lenders. You can purchase these at MyFICO.com or ask a mortgage lender to pull your tri-merge report for an actual current assessment.
3. Pay revolving accounts to below 30% utilization. If you have $5,000 in credit card debt spread across three cards, this is the single fastest path to score improvement — measurable within one billing cycle.
4. Identify which program tier you currently qualify for and which lenders work at your current score. Don’t wait to be “ready” — talk to lenders now, find out exactly where you stand, and get specific guidance on what changes would unlock better program access or pricing.
5. Contact TSAHC or TDHCA about down payment assistance programs before you need them. Eligibility determination takes a brief application; knowing what you qualify for changes your target purchase price calculation and reduces the cash required to close.
