How Your Credit Score Affects Your 2026 Mortgage Rate

Your credit score is the single biggest factor you control that affects your mortgage rate. Lenders use risk-based pricing — the lower your score, the higher the rate. The difference between a 620 and 760 credit score on the same mortgage can exceed $200/month.

Rate Tiers by Credit Score (2026 Estimates)

• 760–850: Best available rates — typically 0.5–0.75% below national average
• 720–759: Near-best rates — minimal premium over 760+ tier
• 680–719: Moderate premium — roughly 0.25–0.5% above top tier
• 640–679: Meaningful premium — 0.75–1.25% above top tier, limited product options
• 580–639: FHA only for most lenders — rates 1.5–2.5% above prime
• Below 580: Very limited options, hard money or subprime products only
