Congrats on your first step...selling your home! We've had several client in town from FL who love it here but can't sell their homes
The Triangle area is a great place and has something for everyone! Our schools are great and Wake county has one of the highest numbers of Board Certified Teachers! There is lots of shopping, low taxes and plenty of employment! There is an abundence of things to do and the beach and mountains are only a short drive.
My suggestion would be to get a relocation package from a real estate agent...they should include info on homes, schools, things to do, neighborhoods, maps, shopping/entertainment, jobs, places or worship etc.... (or maybe that's just me). Search online for homes. When you get a better idea of the area come down...drive around and explore what areas you like and take a look at some homes.
