Not the GP author, but I've been in Nashville for about 8 years total (with a couple year gap in the middle). It's got a lot to offer, but it's become such a 'hot' city for people that you've got lots of recent transplant and tourists and so it's not nearly as affordable as it used to be (still a bargain compared to SV and most coastal cities).

I will say that the tech community here is not great. There have been a few local "success stories" that almost no one outside of town will have heard of, and healthcare still dominates. You also don't have a lot of people experienced in the tech space - I think this is a double edged sword because people starting companies outside of SV is great, but I also think you see lots of companies not be as successful as they could be if they learned from people who have gone there before.

I now work remote and it's a pretty good compromise. I bought a few years ago and love my neighborhood. There are new restaurants and things opening all the time. There are more flights from the airport than ever because of the increased tourism. Traffic is getting worse (still nothing compared to LA, Atlanta, etc.) and it's definitely a popular place overall.

Happy to answer any other questions you have!
