What credit score gets the best mortgage rate in 2026?

Mortgage lenders reserve their best-priced rates for borrowers in the highest credit tiers, and moving up even one credit tier can noticeably change the rate a lender offers on the same loan. Credit score is only one factor though; down payment size, loan type and debt-to-income ratio all interact with it to set the final rate a specific borrower receives. Paying down revolving balances and avoiding new credit inquiries in the months before applying are the most direct ways to improve a score before a lender pulls it. A lender can show a buyer exactly how their current score affects their rate options.
