Multifamily Green MBS

Fannie Mae Multifamily Green MBS is a unique type of Multifamily DUS MBS, which is generally a fixed-income single asset security backed by one loan and one property, providing the investor insight into both the environmental and financial attributes of the asset. In addition to Green MBS, our DUS business allows multiple Green MBS to be packaged together and re-securitized into structured products, like Fannie Megas® (single class pass-through structures) or multiclass Real Estate Mortgage Investment Conduits (REMICs). The REMICs and Megas created from DUS MBS owned by Fannie Mae's Multifamily Capital Markets Desk are called Fannie Mae GeMS™ (Guaranteed Multifamily Structures).

Our Green Bond issuances are backed by properties with Green Building Certifications and existing U.S. rental housing stock that is retrofit to become more energy- and water-efficient, resulting in more affordable homes for families and individuals and more cost-effective properties for owners to operate.

Positive Triple Bottom Line Impact

We measure success by the positive "Triple Bottom Line" impact in our communities—financial, social, and environmental benefits to property owners, renters, lenders, and investors.

  • Financial: Lower credit risk, higher cash flows, and higher property value
  • Social: Greater affordability and higher quality, healthier, more durable housing
  • Environmental: Lower use of energy and water resources, and greater resiliency

We focus on transparency of these benefits through our at-issuance and ongoing disclosures as well as the publication of our annual Green Bond Impact Report.
