There are plenty of pre-fab, or more precisely, "pre- engineered" home companies around. Your house comes bundled up on a flat bed truck, mostly all pre cut. Just assemble as per included instructions.
The only hard part is getting someone to pour the basement or foundation properly.
These are your basic 11-1200 square foot bungalow cookie cutter homes, but some of them actually look pretty good. A handy person can build one themselves, and keep contractor costs to a minimum.

The only problem I see with the pre-fab homes here in Florida is that it is done primarily with stick construction (although much of the site-built homes are too). Whenever a hurricane blows through you see the piles of debris of what used to be the stick homes. If they started doing modular concrete form homes I would consider it. Its like a friend of mine from the Dominican Republic told me when I asked about his parents after a hurricane blew through there years ago, "hurricanes are like the big bad wolf; live in a home of straw or sticks and you are in trouble, but you do okay if in a home of brick."
