Buying a home is the largest financial transaction most people will ever make, and mortgage lenders evaluate credit differently than a credit card issuer or auto lender ever will. They pull all three bureaus at once, use older FICO score versions most consumers have never seen, and apply a "middle score" method that has nothing to do with the number showing up on your phone's free credit app. This guide covers what mortgage-specific credit readiness actually looks like, and links out to a full breakdown of every piece.
The short version: conventional loans generally start around 620, FHA opens the door as low as 500 with a larger down payment, VA and USDA have no fixed government minimum but lenders set their own floor, and jumbo loans typically want 700+. The exact number that matters is not your app score — it is the middle of three separate mortgage-specific FICO scores pulled from a tri-merge report.
Why Mortgage Credit Works Differently
Every other lender you have dealt with — a credit card issuer, an auto lender — typically pulls one bureau and uses a current-generation score. Mortgage lenders pull all three bureaus together in what is called a tri-merge report, and until recently, both Fannie Mae and Freddie Mac required older FICO score versions (FICO 2 from Experian, FICO 4 from TransUnion, FICO 5 from Equifax) rather than the FICO 8 or 9 most consumer apps show. The score used to qualify you is the middle of those three numbers, not the average and not the highest.
