The servicer must report special remittances for all mortgage loans it services to Fannie Mae via CRS, in accordance with C-3-01, Responsibilities Related to Remitting P&I Funds to Fannie Mae.
There are several remittance type codes the servicer can use for reporting special remittances to Fannie Mae. (See the CRS User Guide for a list of remittance type codes). Each special remittance must have a corresponding Fannie Mae loan number provided in CRS.
Each remittance type code must be linked to a single drafting account. See F-1-03, Establishing and Implementing Custodial Accounts for additional information on establishing drafting arrangements.
For more information please see Servicing Guide F-1-21, Remitting and Accounting to Fannie Mae.
