Texas
One of the highest-volume mortgage markets in the US. Lender competition is strong, which typically benefits borrowers who shop multiple quotes.
What This Rate Means for You
A 800+ credit score puts you in the strongest pricing bracket. At 6.125%, a $400,000 loan carries a principal and interest payment of $2,430/month. Borrowers in this tier are well-positioned to negotiate — lenders compete for low-risk profiles.
Your 20% down payment eliminates PMI, which saves most borrowers $100–250/month compared to low-down-payment loans. This meaningfully lowers your effective cost of borrowing even before factoring in the rate.
Texas Housing Market Context
The median home price in Texas is approximately $330K, with a typical loan size around $264K for a 20% down buyer. Texas is one of the highest-volume mortgage markets in the country, with Dallas, Houston, Austin, and San Antonio all producing strong lender competition and typical loan sizes of $220,000–$440,000.
State-level variation in mortgage rates does exist — lender concentration, local competition, and property tax structures all influence the total cost of homeownership. However, the Optimal Blue OBMMI rate used here is a national benchmark. Your actual rate from a specific lender in Texas may be somewhat higher or lower depending on lender pricing, current market conditions, and your full application file.
What Drives This Rate
Credit Score: 800+
Your 800+ credit score puts you in the top pricing tier. Most lenders offer their best available rates at this level.
Down Payment: 20%
A 20% down payment puts you at 80% LTV. No PMI is required at 20% down — a meaningful cost saving versus lower down payment scenarios. Lenders price higher-LTV loans at a slight premium to offset the additional risk.
Market Conditions: 2026
The base rate (6.123%) reflects current 2026 market conditions for a prime borrower (760+ credit, 20% down). Rate adjustments above this base reflect standard Fannie Mae/Freddie Mac loan-level price adjustments (LLPAs) for credit score and LTV.
Frequently Asked Questions
What mortgage rate should I expect with a 800+ credit score and 20% down in Texas?
Based on 2026 market data, the benchmark for a 800+ credit score (Exceptional) with 20% down in Texas is 6.125% for a 30-year fixed conventional loan, derived from Optimal Blue OBMMI rate data. If a lender quotes significantly above this, shopping additional lenders is worthwhile.
Does a 800+ credit score qualify for a conventional mortgage in Texas?
Yes. Conventional loan programs (Fannie Mae/Freddie Mac) require a minimum 620 credit score. A 800+ score qualifies you for conventional financing. Lenders may vary in their exact pricing within this tier, and a higher score within the range may result in slightly better offers.
Is my rate already competitive at 800+ credit?
At 800+, you're in the top OBMMI pricing tier. The benchmark of 6.125% reflects the best available market pricing. If a lender quotes more than 0.25% above this, that warrants a second opinion. Your leverage is high — lenders want low-risk borrowers.
Does putting more than 20% down reduce my rate further?
Conventional pricing tiers for LTV typically cap out at 75% LTV (25% down). Going beyond 25% down generally doesn't reduce your rate further — the pricing improvement has already been captured. Additional cash is usually better deployed elsewhere.
How many lenders should I compare in Texas?
In Texas, mortgage competition is strong — dozens of lenders actively compete for borrowers. Rate spreads between lenders for the same profile frequently exceed 0.375%. Getting 3–4 Loan Estimates (not just pre-qualification quotes) is standard practice and takes less than a week. Each application within a 45-day window counts as one credit inquiry.
How to Know If Your Lender’s Rate Is Fair
The benchmark above is your reference point — it represents the market rate for your exact profile based on actual locked loan data from Optimal Blue. If a lender quotes you more than 0.25% above this benchmark, that gap warrants a second opinion. Lender pricing spreads for the same borrower profile routinely exceed 0.375%, which on a $400,000 loan represents over $75/month or $27,000 over the life of the loan.
