Renter, Charlotte, NC
Coming from a non-realtor, I personally love Denver, but grew up in FM - currently live in Charlotte. If you have a family, Fort Mill is prime for young families because the school systems are top notch. You may also want to keep the Concord area on your radar too if schools are your focus. If you have a good budget and not concerned with schools, just a couple of miles south of Charlotte is the adorable historic Dilworth that is full of the artsy-type young families/singles alike. These houses are old and full of character, but usually around 400k+. Other than Dilworth, the rest of the Charlotte area is real difficult to judge if you're in a good area until you live here a while and really become familiar with the good and bad spots. Almost all of the families in Dilworth send then kids to private schools.
I could go on and on about FM and Charlotte as those are my comfort zones, but just a note on FM --- it's grown exponentially over the past 5-10 years and shows no signs of slowing, so this adds in some traffic and congestion. Also a key area a lot of people have been moving to is around hwy 521 near Ballantyne .... I would jump infront of a moving semi before commuting from that area to Charlotte for work, so beware of that.
Hope this helps!!!
