640 Credit Score Conventional Loan
At 640 conventional prices better than the 620 floor. Lower PMI, a better rate, still just 3% down.

A 640 credit score earns better conventional pricing than the 620 floor. Your PMI eases and your rate improves, while keeping the 3% down option and cancellable insurance. At 640 conventional becomes more competitive against FHA, and for many buyers it is now the cheaper long-term choice.
Pricing Eases at 640
The step from 620 to 640 is real money. Conventional PMI drops and your rate improves, which can shift the FHA-versus-conventional comparison in conventional's favor.
You are still not at prime pricing — that builds through 660, 680, and 700 — but 640 is a solid place to use a conventional loan. We compare it against FHA and, if the property qualifies, zero-down USDA.
