Preparing for the Uniform Collateral Data Portal: Availability Date and New Resources

April 12, 2011

As we continue to develop the Uniform Collateral Data PortalSM (UCDPSM), a single portal for the electronic submission of appraisal data files, Freddie Mac and Fannie Mae (the GSEs) are announcing the portal's availability date and introducing resources to assist lenders in preparing to access and use the UCDP.

Originate & Underwrite and Sell & Deliver

UCDP Available June 27

The UCDP will be available for submitting appraisal data files starting on June 27, 2011. To help ensure a smooth transition to electronic submission of appraisal data files, lenders are encouraged to begin using the UCDP for their live production as soon as it's available. Appraisal report forms for all conventional mortgage loans delivered to Freddie Mac on or after March 19, 2012, must be submitted to the UCDP before the delivery date of the mortgage if:

  • The loan application is dated on or after December 1, 2011, and
  • An appraisal report is required.

Lenders and their designated agents may access the UCDP through one of these access methods:

  • An easy-to-use Web-based interface that allows users to browse and upload XML or PDF files to the portal. Lenders should evaluate their processes and requirements and may want to require the appraiser to send them the appraisal file in XML format.
  • Vendor-provided solutions that offer an integrated system interface to the UCDP. Freddie Mac has published a list of technology vendors that plan to provide a vendor solution with an integrated system interface to the UCDP. This list will be updated frequently over the next several months as vendors are added. Please review the vendor list on

Preparing for the UCDP: New Resources and Key Next Steps

To help you incorporate the UCDP requirements into your business processes, we encourage you to take advantage of these new UCDP resources available on

  • UCDP Overview: This document provides important details on the UCDP, including how it will work, who should use it, how you can access it, and data delivery requirements including the required appraisal report forms.
  • New Questions & Answers: Additional Q&As are now available to address UCDP-related questions. There are also new Uniform Appraisal Dataset (UAD) Q&As. Please make sure you share this information with your appraisers.

In addition to reviewing the resources listed above, it's important to take the following next steps:

  1. Determine Access Method – As identified above, each lender will need to determine how they plan to access the UCDP to submit appraisal data files. Lenders can submit appraisal files directly or may authorize an agent to submit on their behalf. The GSEs will provide more information on the Lender Agent in the near future.
  2. Identify a Lender Administrator – To facilitate the UCDP registration process, lenders are encouraged to start thinking about roles and to determine an appropriate lender administrator in their organization. This person has administrative authority and is responsible for establishing user access and setting up the organization's profile in the UCDP.
  3. Share this information with your vendors and other entities that support your appraisal efforts.

Note: if your organization delivers loans to both GSEs, the primary lender administrator must be the same individual for both GSEs. Although Freddie Mac and Fannie Mae have separate registration processes for the UCDP, the same individual will need to register with both GSEs. The GSEs will communicate registration details in the coming weeks.

Training and Ongoing Support

To help lenders prepare to use the UCDP, the GSEs will provide job aids, training programs, and other resources in the coming weeks. We are also developing a joint GSE call center to support questions related to submitting appraisal data files to the UCDP. We will be communicating more information about the joint GSE call center soon.
