Mortgage brokers doing business with United Wholesale Mortgage will be among the first in the nation with access to a more streamlined origination process, as they can validate income, assets and employment using bank account data from only one asset report. The improved capabilities stem from UWM’s participation in Fannie Mae’s pilot offering of Single Source Validation, a program that Fannie Mae has introduced as an enhancement to its Desktop Underwriter (DU) validation service.
