1) I moved her about 6 years ago from Alaska where I lived for 16 years. I grew up in Alaska and it was all I knew. I do have to say I had a major culture shock moving to Savannah, GA. But I love it. The warm sun, beaches and fun things to do. Everything is pretty close malls, and downtown. Now there is crime downtown but it's our historical section ...also there is crime everywhere.
2) Cost of living is pretty low. Gas is 1.60 per gallon. I feel it's lower than average.
3) Cost of land depends on where you look. Islands are more expensive and are older homes. The lots are smaller also. If you go out to say Pooler or Bloomingdale you could get a nice plot of land for decent and build your own house on it. However I think due to possible flood potential being so close to shore that we don't have basments. ;/
4) we also get hurricanes but we get lucky and it's been years since Savannah has been hit. So mainly we get thunderstorms and possible windstorms. Nothing really more than that.
I hope that helps you in determining where you want to live!!! Good luck!
My brother lives in Anchorage, I keep trying to talk him into moving down to the lower 48, but him and his wife are worried about the heat/humidity
