I moved back to NC. about 7 years ago after a long time in FL.
I cannot recommend FL at all as a place to live.
NC. is pretty nice , it is never too cold or too hot for too long , property is reasonable , taxes and insurance are reasonable most places here. I am in the Piedmont area, about 2.5 hours from the highest of the mountains, 45 minutes from the BRP, and 4 or 5 hours from the east coast.
Good medical and educational facilities close by, a thriving arts and entertainment area.
Winston Salem area is highly rated as an area to retire in.
I would also look closely at TN. I am told the taxes are less there.
