A Recent Shift Worth Knowing About: Fannie Mae eliminated its hard minimum credit score requirement in its Selling Guide as of November 2025. This doesn't mean conventional loans are now available to anyone regardless of credit — individual lenders still set their own requirements — but it signals more underwriting flexibility on the conventional side than the old "620 hard floor" framing suggests.

The Number on the Program Page Isn't the Whole Story

Loan programs publish minimum scores, but individual lenders often add their own "overlay" — a stricter internal requirement, typically 20-40 points above the program minimum. A program might technically allow a 580 score, but the lender you're working with may require 620 in practice. This is exactly why working with someone who knows the actual lending landscape, not just the published guidelines, matters.

How Your Score Affects Your Rate, Not Just Your Approval

Credit score requirements get the most attention, but the bigger financial impact for most borrowers is how their score affects their rate. Conventional loans in particular use credit-tiered pricing: borrowers with scores of 740 or higher typically get meaningfully better rates and lower down payment requirements than borrowers in the 620-679 range, even though both groups technically qualify for the same loan program.

⚠️ Don't Assume You're Stuck With FHA If Your Score Is Borderline: If your score sits below roughly 680, FHA's flatter risk-based pricing structure can sometimes produce a more affordable monthly payment than a conventional loan at that same score, even with FHA's mortgage insurance factored in. It's worth comparing actual numbers side by side rather than assuming "lower score means FHA is automatically required."

If Your Score Isn't There Yet

Moving from the 500s into FHA-qualifying territory (580+) typically takes a few months of focused work. Climbing from the low 600s into the 700+ range that gets the best conventional pricing takes longer, but the fastest improvements usually come from two sources: disputing credit report errors, and paying down high-utilization credit cards. Both can move your score meaningfully within 30-60 days in many cases.
