This is probably the main problem for the Florida housing. Since I'm a mortgage lender I'll write from a professional viewpoint.
The manufactured home industry in the Southern states suffers from a stigma of older, inferior homes and the shady business practices of those who sold them.
The new manufactured homes are a great value. When placed on a permanent foundation, they are titled as real estate --not chattel property (like a car)and are appreciating in value.
They are a great buy for retirees. I write about one mortgage a month for manufactured and the demand is only growing.
Perceptions of this product are changing favorably with the buying public and lenders.
Do the manufactured homes still have to be secured with earth anchors?
