In its much anticipated duty-to-serve final rule issued last week, the Federal Housing Finance Agency gave the green light for Fannie Mae and Freddie Mac to begin pilot programs for manufactured housing “chattel loans.” Although duty-to-serve was mandated eight years ago to make sure the GSEs support three underserved markets, (such as manufactured housing,) it was never implemented. The other markets are affordable housing preservation and rural housing. A proposed rule was issued in December 2015 and it’s taken a year to issue the final rule. The FHFA sifted through hundreds of comments on the proposed rule earlier this year, most focusing on the need for greater GSE support when it comes to manufactured housing lending.
