Greenville and Charleston, SC are working pretty hard to become tech hubs. Charleston is booming to a degree that housing is starting to go the way of SF (which is nuts in this area) but Greenville and it's surrounding cities have virtually no risk of that degree of price inflation. There's just too much land and space.
I live in Easley, which is about 10 minutes from downtown Greenville and you can get a decent 1100 square foot, 2 BR/2BTH apartment with washer/drier for about $500 / month.
Houses tend to run between 80-110 / sqft.
Also, food is awesome: https://www.youtube.com/watch?v=73GcUAb2HO0
