Fannie Mae and Freddie Mac UAD Update

January 29, 2013 – Uniform Appraisal Dataset Update and Uniform Collateral Data Portal Release Notification

As communicated in the September UAD Update, Fannie Mae and Freddie Mac (the GSEs) will convert several of the current Uniform Appraisal Dataset (UAD) compliance warning edits to fatal UAD edits in the Uniform Collateral Data Portal® (UCDP®) during 2013. The first phase, targeted for implementation in June 2013, will include warning edits for the following data fields converting to fatal UAD edits:

  • Appraisal effective date
  • Subject contract price and comparable sale price
  • Above grade Gross Living Area (GLA) (subject and comparables)
  • Sale type (subject and comparables)

Warning edits for the following data fields will convert to fatal UAD edits in phases that will be scheduled during the second half of the year:

  • Subject and comparable address (including unit number for condominiums)
  • Subject contract date/ Comparable date of sale/time
  • Condition rating (subject and comparables)
  • Quality of construction rating (subject and comparables)
  • Location rating (subject and comparables)
  • View rating (subject and comparables)

Each of the  data fields in the lists above has associated UAD edits that will be returned by the UCDP if the data provided is incomplete or in an invalid format as defined in the Fannie Mae and Freddie Mac UAD Specifications.  After these warning edits are converted to fatal UAD edits, if one or more of these edits is issued, it will result in Hard Stop 401 (UAD Compliance Check Failure) and a “Not Successful” status will be issued in the UCDP.  If the lender or appraisal vendor receives a “Not Successful” status in the UCDP, the lender or vendor must resubmit a corrected appraisal with the required data in the correct format to ensure a “Successful” status.

Furthermore, in order to ensure that the UAD data submitted to the UCDP is of high quality and compliant with Fannie Mae’s and Freddie Mac’s  data standards, the GSEs are announcing their intent to discontinue accepting appraisals in PDF and other alternative appraisal formats, and to accept only the MISMO file format in the UCDP. Their goal is to retire UCDP acceptance of the ACI XML and AIReady formats, and the PDF extraction services. They have initiated conversations with key vendors associated with the non-MISMO XML formats, and will work closely during 2013 with lenders and vendors using these formats to ensure a smooth migration path for lenders.  Once a retirement date has been determined they will provide at least six months’ notice of any formal retirement. The GSEs will provide more updates on our progress throughout the year.
