C2-1.1-01, Mandatory Commitment Process (10/30/2009)


This topic provides information on the process lenders use to obtain a mandatory commitment to sell whole loans to Fannie Mae.

Mandatory Commitment Process

To obtain a mandatory commitment to sell whole loans to Fannie Mae, lenders may use Fannie Mae’s whole loan committing application, a free Web-based application available to subscribers, or may contact the Capital Markets Pricing and Sales Desk (see E-1-03, List of Contacts). Lenders can obtain information on subscribing to the whole loan committing application by contacting their Fannie Mae customer account team or the Capital Markets Pricing and Sales Desk, or by referring to Fannie Mae’s website.

Lenders can obtain commitments on any weekday, with the exception of bond market observed holidays as defined by the Securities Industry and Financial Markets Association (SIFMA).

Fannie Mae confirms its acceptance of the lender’s request for a mandatory commitment by electronically transmitting a commitment confirmation to the lender. If Fannie Mae is unable to process the electronic transmission, lenders are notified promptly. Should a lender have a problem receiving a commitment confirmation, it should immediately contact the Capital Markets Pricing and Sales Desk.

If the lender has obtained the commitment by contacting the Capital Markets Pricing and Sales Desk, the legally binding terms of the commitment are captured in a recorded telephone conversation between the lender and the Desk.
