An area 35 miles from downtown Gastonia includes all of Charlotte and parts of 11 counties. This is a very large area and there are many public and private schools that are highly ranked. You might want to read the Trulia Real Estate Blog: "Which areas surrounding Charlotte would be a nice place to relocate?" There are some detailed suggestions about schools and locations there. If you have a full time agent with a Masters degree in Planning with Finance and over two decades of experience, working for you, you will likely do better in negotiations. I'd be pleased to provide that service. If you appreciate this answer, please give it a thumbs up, or if this was the most helpful answer, please say thanks with a best answer click.
Your best bet is always going to be a visit to the individual schools. By personal observation, you will "know" whether or not a school is the right fir for your child. You can interact with administration, teachers and parents at the same time.
Good luck in your search!
