The servicer must request reimbursement for advances it has made for property taxes, insurance premiums, applicable HOA dues, and other out of pocket expenses by submitting a request for expense reimbursement.
Fannie Mae will allow the servicer to submit requests for reimbursement as soon as possible after incurring an expense. When multiple requests for reimbursement are submitted in connection with the same mortgage loan, the servicer must submit its final request for expense reimbursement for expenses incurred during the disposition process within 60 days of the applicable milestone.
Note: If the servicer submits a request for reimbursement of advances after the date Fannie Mae specifies for the submission of the final request for expense reimbursement, Fannie Mae will deny the request.
