MBS News and Announcements

Property Valuation Method Attribute Now Available

In January 2020, Fannie Mae announced it would enhance its Uniform Mortgage Backed Securities (UMBS®) and Mortgage-Backed Securities (MBS) disclosures to include a new attribute, "Property Valuation Method," that indicates the method by which the value of the subject property was obtained.

  • Beginning today, the at-issuance Loan-Level and Security Supplemental intraday files will include this new attribute for all newly issued securities.
  • On Thursday (Business Day 4), the MBS Monthly Loan-Level and Security Supplemental files will include the new attribute for all outstanding securities issued on and after January 1, 2017.

The Property Valuation Method FAQs and the Single-Family MBS Disclosures Guide provide additional details related to the new Property Valuation Method disclosure attribute, including enumerations, definitions, and file format specifications. Per the January 2020 announcement, the PoolTalk® application and Prospectus Supplement have also been updated.
