Thanks for your question. I work in the Nashville market specifically.
I like Nashville because of our well rounded economy. We are a strong business and recreation economy.
As you alluded to, we're seeing that Eastern Tennessee is getting very saturated and that the price for home very rarely makes sense for what you can expect in revenue in years 1,2, or even 3. In Nashville we have city ordinances and zoning to think about. I don't necessarily think this is all bad because it has helped reduce the likelihood of over saturation compared to other markets like Pheonix, Arizona or some parts of Easter Tennessee.
That being said, most of what we're seeing on the market in Nashville that is zoned correctly is also overpriced however my team includes myself and a former high level short term rental manager (300+ Units) in Nashville that assists my clients in finding the absolute best deals on and off the market. A Short term rental eligible property is almost the "creme-de-la-creme" property. It's only going to continue to appreciate and you'll have alot of options on what to do with it because of the zoning.
It sounds like you've got other reasons beyond just the cashflow to make the move.
