When I lived in NC, one of the main features of modular housing was the ease of getting land. Oftentimes a trailer (what others might think of as a semi on wheels, but actually REALLY nice if you get a new double or triple-wide) would have problems in finding a site.
The wife and I looked into buying a modular house, but at the time, getting a lot and house built wasn't extravagantly more than a modular house. Resale values for modular houses at that time weren't as good as a "regular" house, but that may have changed. The resale value negated any savings, so we stopped looking at 'em. Nice area you're moving to as well.

I've got friends who live about 15 minutes from where you're moving to. We went to visit 'em when a hurricane was gonna blow right through our town. Don't think you won't have to worry about hurricanes. You just won't have to worry as OFTEN about them. There ARE all kinds of things they manufacture into homes there to help with stuff like that though.
I think you'll like your new modular home very much
