First it was Clarksville, TN for long term rentals ( LTR) then they decided (“they,” - out of state investors from WA, OR, CA) to move to STR rentals in Gatlinburg as an active income source.The pro of the decision is that rates are great in that area however it might be more saturated since its the “talk of the town,” along with all the other touristy places like the Pocano’s in PA or Palm Springs/Coachella, CA, / etc.However, from a high level approach you’ll want a high income activity or active income machine (for some this is a tech job, an actual business, or STR they operate) and then the passive income sources.

Maybe, I'll go and explore a new market like  @Jonathan Mednick was mentioning or get a time machine and go back to 2012.

Last time I was there on a bachelor party my buddy tossed a buck in a slot machine as we were heading out the door and won $1,000.

I generally find that these machines will hold up pretty well if cared for and kept away from dust.
