This week, Fannie Mae launched an initiative that guarantees to alleviate buyback fears on certain loan components for lenders using its underwriting and appraisal tools. Fannie will also automate key processes of verifying loans, including income, through Desktop Underwriter’s new validation service.Under Day 1 Certainty, Fannie said lenders would be relieved from most representations-and-warranty risk related to verifying a borrower’s income, assets and employment using DU. “Those are the big ones,” a Fannie spokesman told Inside The GSEs. He said, “It validates right there and they are good to go,” adding that this is the kind of innovation that helps makes possible programs like Quicken’s Rocket Mortgage.
