This communication relates to the Uniform Mortgage Data Program
®
, an effort undertaken jointly by Fannie Mae and Freddie Mac at the direction of the
Federal Housing Finance Agency.
UCDP Access
UCDP provides a common pathway for the electronic submission of appraisal data files to the GSEs. Lenders and/or their
agents can submit appraisals to Fannie Mae, Freddie Mac, or both GSEs. A lender agent is an entity that a lender
authorizes to perform functions within UCDP, such as uploading appraisals and evaluating results.
Lenders and their designated agents can access UCDP through:
▪ An easy-to-use web-based interface that allows users to browse and upload appraisal files to the portal.
▪ Vendor-provided solutions that offer an integrated system interface to UCDP. Both GSEs have published a list
of technology vendors who provide a vendor solution that offers an integrated system interface to UCDP.
Please review the vendor lists on each GSE’s website, FannieMae.com and FreddieMac.com.
Supported Formats
An XML data stream (output from appraisal forms software) with an embedded first-generation PDF file must be submitted
to UCDP. The following XML format is supported in UCDP:
▪ MISMO
®
2.6 Errata 1 GSE Extended format
The following XML formats are supported in UCDP for the non-UAD forms:
▪ MISMO 2.6 Errata 1 format
▪ MISMO 2.6 format
All XML files must include an embedded PDF file that includes all appraisal exhibits, addenda, and photographs.
Submission of a MISMO XML file obtained from the appraiser is the most efficient and reliable method of submission to
UCDP.
N O T E : The Appraisal Update and/or Completion Report (Fannie Mae 1004D / Freddie Mac Form 442) must be
submitted in MISMO 2.6 Errata 1 format.
UCDP Functionality
Users can submit electronic appraisal data files, receive status and findings, correct and modify appraisal file
submissions, and request overrides in some instances when the appraisal is not accepted by UCDP. Appraisals submitted
to UCDP go through a series of checks, including a UAD Compliance Check. The UAD Compliance Check may result in
errors that require appraisals to be corrected by the appraiser and re-submitted to UCDP. Appraisals that pass all checks
receive a “Successful” status from UCDP.
All appraisals successfully uploaded to UCDP receive a Submission Summary Report (SSR) for each GSE submission.
The SSR contains a summary of the appraisal submission(s) for each loan, the status of the submission(s), and a
Document File Identifier (Doc File ID), which is part of the unique appraisal identifier generated by UCDP. One Doc File ID
is assigned per loan and is the same for delivery to either GSE. Lenders are required to deliver a Doc File ID to each
GSE’s loan delivery system as part of the loan delivery process. An appraisal must be submitted to UCDP and receive a
“Successful” status on the SSR before the loan is delivered to the GSE.
UCDP features an Appraisal-Sharing functionality which allows correspondent lenders to share individual appraisals with
specific aggregators, and provides the ability for aggregators to view the submission status, findings, Doc File ID, and
SSR of each shared appraisal.
