I like Nashville and have been thinking about doing just that move: http://seliger.com/2017/10/23/nashville-seen-unseen. It's part of the “The new boomtowns: Why more people are relocating to ‘secondary’ cities,” https://www.washingtonpost.com/realestate/the-new-boomtowns-..., as zoning madness keeps driving the costs of cities like NYC and LA up and up and up.

Still, it's notable to me that Nashville has committed to long-term traffic: https://www.citylab.com/transportation/2018/05/what-went-wro... in way that other cities have not. Denver, for example, keeps building out new rail lines: http://www.rtd-denver.com/Fastracks.shtml.
