DUS Disclose Information Center

Welcome to the DUS Disclose® Information Center. DUS Disclose launched on December 4, 2017, and is the new Fannie Mae Multifamily disclosure website, replacing the Multifamily Securities Locator Service (MFSLS). It increases the data available for Multifamily securities in alignment with the industry, as well as provides an updated, user-friendly interface.

On November 1, 2018, Fannie Mae implemented enhancements to DUS Disclose which expanded disclosure data for Multifamily REMICs and created separate Multifamily Factor Files. Please read the related announcement for full details.

The documents below are provided to assist users with this transition to separate Multifamily disclosure information. We will continue to update this page with information about changes to DUS Disclose.
