I lived in a block home in Florida for 40 years before we retired and bought a double-wide, about 2400 sq ft . It is a 2006 model and has all the niceties and a great layout. They altered their basic plan because I wanted sliding glass doors instead of regular doors. Now my glass doors open onto a deck in the front and a 40+ foot roofed screened porch in the back with an additional 20+ foot carport that we use as a shop. It has a fireplace, too. All for about half of what my daughter paid for her 1800 sq ft block house. The total was $104,000--but that included the porch, the deck, the carport, a barn, clearing a road to the barn, fencing, and a few other extras.
The first week we were here, the house withstood high winds--a tornado passed at the foot of our road, taking out 3-4 houses. We had one blown-out screen on the porch. That was all. It didn't even "rock" on its foundations or anything.
We chose manufactured because of Katrina. All the builders were in New Orleans rebuilding and the soonest anyone was willing to start a house for us was a year away. The local Home Depot wouldn't even guarantee enough wood to frame it. Problem was our home in Florida was sold and we had to be out in 60 days. We had the acreage so, in desperation, I looked at a few websites, found a layout I liked, and was told by the manufacturer that it could be turnkey in 60 days. We actually moved in 2 weeks earlier than that!
