Conforming Loan Conventional mortgage loans that are not eligible for sale to either the Fannie Mae, Ginnie Mae or Freddie Mac. Nonconforming loans (which are generally more expensive than conforming programs) are an alternative to the highly selective and restrictive conforming loans acceptable to Freddie Mac and Fannie Mae. Unlike portfolio loan, however, nonconforming loans are still sold on the secondary market - just not to Fannie Mae and Freddie Mac. For more information, see the "Nonconforming Loans" article in the "Loan Programs" section.
