I never personally lived in Waxhaw, but my in-laws lived there for a few years. I've lived in Monroe, Weddington, and Wesley Chapel (all near Waxhaw). Now I'm on the other side of Charlotte near Gastonia, and I do miss Union County sometimes.
Waxhaw was a very nice town from what I remember. You get that southern small town feel while still being near a big city. Commuting from that area to Charlotte was always tough during rush hours, though.
Good luck with your move!
