Tennessee, known for its affordability, low taxes, and growing economy, has cities like Nashville experiencing significant growth.

@Andrea Evans - Chicago is truly block by block, yet also has a population the size of Boston, Denver, Milwaukee and Nashville combined.

First post here ...I currently have a STR in Nashville, TN.

With respect to your question about the market in Nashville for rentals, I don't know really since this home was my primary home that I rented only because I needed to move out of state on short notice.

I currently live in Nashville TN.

Think of Nashville, Vegas, Miami, Orlando Disney, Anaheim Disney.

Make sure you can find someone good to manage the property if needed.Good places to look include Midwest Cities like Indianapolis, Kansas City, and Cincinnati, Southeastern Cities like Atlanta, Charlotte, and Nashville, and Texas Cities like Dallas, Houston, and San Antonio.

so just let it rip and buy that 100 unit complex in Nashville at a 3% cap rate, what could possibly go wrong?

I've also done some high level analysis of Nashville TN, Tampa FL, and the state of Georgia.
