On March 11, Fannie Mae and Freddie Mac published the Uniform Closing Dataset’s (UCD) MISMO-mapping document, Appendix B: Closing Disclosure Mapping to the MISMO v3.3 Reference Model, which provides a common dataset to implement the CFPB’s closing disclosure. While Fannie Mae and Freddie Mac have not yet determined the method or timeline for collecting UCD from lenders, the release allows lenders and their vendors to begin preparing for the collection.
