A conventional mortgage is one that’s not guaranteed or insured by the federal government.

Most conventional mortgages are “conforming,” which simply means that they meet the requirements to be sold to Fannie Mae or Freddie Mac. Fannie Mae and Freddie Mac are government-sponsored enterprises that purchase mortgages from lenders and sell them to investors. This frees up lenders’ funds so they can get more qualified buyers into homes.

Conventional mortgages can also be non-conforming, which means that they don’t meet Fannie Mae’s or Freddie Mac’s guidelines. One type of non-conforming conventional mortgage is a jumbo loan, which is a mortgage that exceeds conforming loan limits.

Because there are several different sets of guidelines that fall under the umbrella of “conventional loans,” there’s no single set of requirements for borrowers. However, in general, conventional loans have stricter credit requirements than government-backed loans like FHA loans. In most cases, you’ll need a credit score of at least 620 and a debt-to-income ratio of 50% or less.
