How much does my credit score affect my mortgage rate in Massachusetts?
Significantly. Moving from a 580 credit score to a 760+ score can reduce your rate by up to 4.0 percentage points — a difference of hundreds of dollars per month on a typical loan. Every 20–40 point improvement in credit score moves you into the next pricing tier.
Does down payment affect my mortgage rate in Massachusetts?
Yes. Going from 3% down to 20% down reduces your rate by approximately 1.0 percentage point and eliminates the PMI requirement. The rate improvement reflects the lower lender risk at a lower LTV. Borrowers who can put 20% down save on both rate and monthly insurance costs.
What is the minimum credit score for a mortgage in Massachusetts?
For a conventional loan, most lenders require a minimum 620 credit score. FHA loans allow scores as low as 580 with 3.5% down. VA and USDA loans have no official minimum but most lenders set a floor around 580–620. A higher score doesn't just qualify you — it lowers your rate at every tier above the minimum.
