Forclosures have doubled here in Atlanta in the past year.
Georgia foreclosures jump 99%, rate is nation's 3rd highest

    This in a city whose economy owes a rather large part of its existence to suburban and exurban ex p  a   n    s       i       o           n... that and tourism and trade shows, which are themselves vulnerable - not exactly much of the P in "E.L.P.".

I've seen them used a lot in the oil patch for storage, as well as at a lot of companies for temporary storage. Hope your wife isn't into fashion and elegance.
Funny you should mention... it was her idea. The containers themselves are dirt cheap right now though, leaving plenty of money for renovation to make it look like a "real" house. Plus, if designed right, they're relatively immune to all types of natural disaster (including the straight-from-the-pages-of-the-worst-doomer-porn zombie hordes.)
