33. Limitation on emergency grant payments - interim mortgage assistance. 42 U.S.C. 5305(a)(8) is modified to extend interim mortgage assistance to qualified individuals from 3 months to up to 20 months. Interim mortgage assistance is typically used in conjunction with a buyout program, or the rehabilitation or reconstruction of single-family housing, during which mortgage payments may be due but the home is uninhabitable. The time required for a household to complete the rebuilding process may often extend beyond 3 months, during which mortgage payments may be due but the home is inhabitable. Thus, this interim assistance will be critical for many households facing financial hardship during this period. Grantees may use interim housing rehabilitation payments to expedite recovery assistance to homeowners, but must establish performance milestones for the rehabilitation that are to be met by the homeowner in order to receive such payments. A grantee using this alternative requirement must document, in its policies and procedures, how it will determine the amount of assistance to be provided is necessary and reasonable.
