Southern NC? Do you mean the Wilmington area, in the eastern part of the state? Or the Charlotte area, in the middle of the state? There's a big difference, climate wise. Your location is important, there is a mix of different grass's in this state.
Coming from upstate NY your going to notice that the cost of living is a lot lower here, but so are wage's. If you are moving to the eastern part of the state the humidity in the summer is going to be brutal at first.
