Re: I'd love to hear from South Carolina and Georgia Mamas...
I also recommend Charleston! Actually Mt pleasant would be perfect.
I think your most important factor is a job for your dh. I don't know what he does exactly, but he might be able to work as a contractor for the Navy or for International Paper. My dh used to be a Nuclear Engineer, and did some of his training in Charleston. I met him while I was going to college there.
Not so sure about home prices, but you can go to real estate sites to figure that out. Everyone has different ideas about what is nice, etc so I think that is your best bet.
There are also good hospitals there, including MUSC.
I think Summerville might be too far out job wise, but you could get a lot more house there.
