Green Bonds
Our green efforts support the Single-Family and Multifamily housing markets by financing homes and rental communities that meet energy- and water-saving standards.
Multifamily Green MBS
Offered through our Multifamily Delegated Underwriting and Servicing (DUS®) business, each DUS MBS is generally secured by a single Green mortgage loan collateralized by one property and features guaranty of timely payments, stable cash flows, and liquidity.
