As part of its Multifamily Green Initiative, Fannie Mae is granting a 10 basis point reduction in the interest rate of a refinance, acquisition or supplemental mortgage loan for a multifamily property carrying certification or recognition under USGBC LEED, EPA Energy Star or Enterprise Green Communities programs. On a $10 million dollar loan amortizing over 30 years, an owner would save $95,000 in interest payments across a 10-year term based on 3.9 percent versus 4 percent market rate.
