The amount of principal required to be reported to Fannie Mae to effectively pay off the mortgage loan varies based on the remittance type of the mortgage loan. The different calculation methods are explained in the following table.
Note: For an actual/actual, scheduled/actual or an actual/actual biweekly remittance type loan, if there is movement in the Loan’s LPI date or Actual UPB, the change in the UPB will need to be accounted for in the principal amount to be reported. Also, if the mortgage loan has principal forbearance, the servicer must add the forbearance amount to the UPB before multiplying by the purchase price and/or Fannie Mae’s percentage interest.
