The line has been blurred between mobile homes and stick built homes, with ‘manufactured’ homes, on permanent foundations...and even basements.
I did work for a housing developer who did an entire development with manufactured homes - no problems. Then HUD and FHA changed their rules...no HUD financing option for buyers, had to go back to stick built.
Anyway, I like manufactured homes, and have no problem with them. However, a large segment of potential buyers have been peeled away - so their value may not grow at the same pace of stick built.
Up until 2008 FHA did insure financing of manufactureds on acreage, so long as the foundation construct complied with specific requirements. The supports had to be mortared, not dry-stacked, and the tie-down material requirements were more stringent. Has that changed since?
