Conventional loans are classified as such because they're not insured by the federal government. There are two types of conventional loans: conforming and non-conforming.
Conforming conventional loans are backed by the Government-Sponsored Enterprises (GSEs) Freddie Mac (Federal Home Loan Mortgage Corporation) and Fannie Mae (Federal National Mortgage Association). They are issued to borrowers who meet all of the GSEs’ income, credit, debt, and other requirements.
Non-conforming loan borrowers do not meet the requirements set forth by the GSEs. This can be for a number of reasons. A typical example of a non-conforming loan is a jumbo loan: a mortgage loan amount so large it exceeds regional GSE maximums. Non-conforming conventional loans are usually accompanied by higher rates than their conforming counterparts.
Because non-conforming conventional loans vary, the minimum requirements below are for conforming conventional programs only, and reflect GSE standards. You can find information about jumbo loans on our jumbo programs page.
