If you move to be CLT based, I would recommend moving to SC. It is only about a 20 minute drive depending on traffic from Ft. Mill, SC to the airport. And the schools are better there and cost of living is cheaper. However they do not take SC state taxes out of your paycheck. So come April 15th, you will owe. Unless you pay quarterly taxes of course.

As far as TYS, I cannot speak for the schools. But the cost of living is cheap, especially in Maryville. And there is no state tax to be taken out of your check.
