My parents moved to Charlotte, NC in 1999. It amazes me the sheer growth in HOUSING in city center. There are several new buildings well beyond 6 stories. There are even more new buildings in the 3-8 range in areas like South End. There are even more single family homes further out of the city.
It may not be perfect, but it's seriously beautiful and developed nicely in the last 20 years.
It can't be understated what a huge impact the Lynx Blue Line (light rail) had on Charlotte's ability to shape and concentrate their growth in the past 15-20 years. Developers started planning and building around it well before it opened. Strong transit can make a huge impact on affordability, especially if it frees families up from the burden of car ownership (expensive depreciating assets with large operating costs).
