A “super-conforming loan” is another name for a high-balance loan. Fannie Mae and lenders who chiefly sell their mortgages to Fannie Mae tend to prefer the “high-balance” terminology, while Freddie Mac and lenders who sell to it lean toward “super conforming.” Both denote loans in amounts that exceed the FHFA’s national baseline conforming loan limit but fall within the maximum conforming loan limit for a county the FHFA designates as a high-cost housing market.
