ACE (automated collateral evaluation) is a Freddie Mac appraisal waiver solution and NAN is a verified software partner for the PDR (Property Data Report) solution. ACE+ PDR (automated collateral evaluation plus property data report) is a new capability that allows lenders to originate cash-out and certain no cash-out refinance loans without an appraisal. With ACE+ PDR, additional property information is physically collected on-site by trained data collectors using the Freddie Mac PDR dataset, in lieu of an appraisal.

Delivering the ACE+ PDR through Freddie Mac’s bACE API

As you may have heard, Fannie Mae and Freddie Mac have worked together to develop the Uniform Property Dataset (UPD). The UPD consists of all required, conditionally required, and optional data elements for GSE property data collection and supports a full interior and exterior data collection, with images and floor plan for the subject property. To get ahead of this integration and delivery, we are asking our lender partners to move forward with the recent release from Freddie Mac advising lenders to establish the relationship with their waiver providers (NAN) within Freddie Mac’s Loan Advisor.
