Fannie Mae introduced a program this month to boost manufactured home ownership by giving manufactured housing properties the same advantages as site-built homes. Manufactured housing under the MH Advantage initiative is designed to meet specific construction, architectural and energy efficiency standards that are more in line with site-built homes.Fannie explained that the specific architectural and aesthetic features include a higher pitch roofline, lower profile foundation, garages or carports and dormers. The MH should also be built with more durable siding materials and energy efficiency standards. One of the goals is to encourage more consumers to consider manufactured homes and help bridge the gap in affordable housing.
