Fannie Mae is adding three proprietary appraisal messages in the UCDP, effective the weekend of April 11, 2015. But rest assured, Mercury Network clients are ready.
You will see these messages in your direct UCDP integration through Mercury Network in the same way you see all the other messages.
If you have any questions, don't hesitate to contact your Client Relations team at 1-888-794-0455.
