There was a thread addressing this issue floating around somewhere but I'm too lazy to search for it. A just released letter from the MHD now allows Realtors to sell mfd homes that are ON the property. Prior to this Realtors weren't supposed to sell homes that were not attached to the real estate with a permanent foundation.
"...Please note however, that Realtors® may only sell manufactured homes that are located on real property. The homes do not have to be permanently affixed to the real property with a permanent foundation to be sold by a Realtor®, but they must be located on, and sold with, real property.
Anyone, Realtors® included, who sells more than one manufactured home per year as chattle (personal property), must be licensed by MHD.
Realtors® may lease and/or serve as property managers of manufactured homes. "
