A conforming loan is a conventional mortgage that follows the rules set by Fannie Mae and Freddie Mac — most importantly, it stays under the loan limit the federal government adjusts each year (higher in expensive counties). Loans above that limit are jumbo loans.
Why borrowers care: because Fannie and Freddie buy conforming loans from lenders, lenders can price them efficiently and pass the risk along. That usually translates into lower rates, smaller down payment options, and more forgiving qualification than jumbo financing offers.
Conforming also means meeting the agencies' standards on credit score, debt-to-income ratio, and documentation — not just the size cap. If your loan amount hovers near the limit, even a slightly larger down payment can pull you under it and unlock noticeably better pricing.
Keep the categories straight: every conforming loan is a conventional loan, but not every conventional loan conforms. Check current pricing on our mortgage rates page.
