Fannie Mae creates single-class MBS that represent beneficial ownership interests in a pool of mortgage loans secured by one or more multifamily (five or more units) residential properties.

Creating a Multifamily MBS begins with a mortgage loan made by a lender to a borrower to finance the purchase or refinance of a multifamily property (property types include Conventional Multifamily, Cooperative Housing, Dedicated Student Housing, Manufactured Housing and Seniors Housing). We pool multifamily loans that generally conform to our standards and issue Multifamily MBS backed by those loans. A Multifamily MBS may be backed by fixed-rate mortgage loans or adjustable-rate mortgage loans but will not be backed by both fixed-rate and adjustable-rate loans. When a Multifamily MBS is issued, we guarantee to the MBS trust that we will supplement amounts received by the trust as required to permit timely payment of principal and interest on the MBS certificates.

Multifamily MBS may be placed into Megas, REMICs, or other Structured Transactions.
