A jumbo loan, also known as a jumbo mortgage, is a type of financing that exceeds the limits set by the Federal Housing Finance Agency (FHFA). Unlike conventional mortgages, a jumbo loan is not eligible to be purchased, guaranteed, or securitized by Fannie Mae or Freddie Mac.

Designed to finance luxury properties and homes in highly competitive local real estate markets, jumbo mortgages come with unique underwriting requirements and tax implications. These kinds of mortgages gained traction as the housing market recovered following the Great Recession.
