Fannie Mae and Freddie Mac multifamily lending is booming and hit a record high in 2016, but how long will that streak last? Some say the supply and demand dynamics are changing as developers rushed to build to meet a growing demand that may be leveling off some this year.Fannie ended last year having provided $55.3 billion in financing and support of the multifamily market. In 2016, Freddie financed $56.8 billion in loan purchases and bond guarantees. “Credit performance of the book of business was strong in 2016. The number of multifamily foreclosed properties held for sale remained low at 13 properties as of December 31, 2016,” reported Fannie.
