The GSEs recently introduced a new loan dispute procedure that lenders should use prior to engaging a third-party arbitrator. Fannie Mae and Freddie Mac launched their independent dispute resolution process early in the year as the final piece to the representation-and-warranties framework to help prevent buybacks.This process uses a neutral third-party arbitrator to determine a final, binding decision about whether there was a loan violation.However, the new impasse and management escalation process, announced last week, is intended to serve as an intermediary between the normal loan dispute appeal process and the final IDR process for seller/servicers.
