On December 4, Fannie Mae issued Servicing Guide Announcement SVC-2013-24, which: (i) updates the modification terms for the “Cap and Extend Modification for Disaster Relief” to require servicers to set the interest rate to a fixed rate; and (ii) establishes the steps servicers must follow to determine borrowers’ modified payment terms. Fannie Mae encourages servicers to implement the new requirements immediately, but will not require them to do so until February 1, 2014. The announcement likewise requires, with immediate effect, that servicers update Form 582 (Lender Record Information) promptly after any change in previously-submitted information occurs. Finally, the announcement adds to the Servicing Guide glossary a definition for “seriously delinquent mortgage loan.”
