Fannie Mae announced this week it can change pricing and other terms under purchase agreements and mortgage-backed securities contracts with lenders should the GSE deem it necessary. According to the alert to servicers, Fannie is asserting its right to change pricing terms under standard purchase agreements, master agreements or mortgage securitization contracts. For any contracts and agreements entered into on or after May 1, Fannie said it reserves the right to change pricing one or more times during the term. Such changes may include the base guaranty fee, loan-level price adjustments and guaranty-fee adjustments on mortgages delivered under mortgage-backed securities contracts or as whole loans.
