Little Rock has been a popular market for investments for some time now.

And then when the distributions got paused tell the same customers, who really needed those funds for retirement, they were being short-sighted to focus on de minimis cash flow and should wait for the real money to come in via appreciation?

I've looked into Guesty (which seems too expensive for what I hear to be awful customer service), Hostaway, Owner Rez, and Lodgify.

These are very personal decisions.I can't tell you how many times I had a seller pay me to go in and redo kitchens and baths, and then get called back by the new buyer to redo the brand new custom work....just because of color.I would just put the house on the market and price it a little high, maybe $20k...?

You say that they weren't popular before but are now.

Implement themed experiences like a "Movie Night" with popcorn and streaming access or a "Game Night" with popular board games.

Some people want cash-flow from day 1, some people want to invest long term, some medium term... all different strategies that would require a custom tailored approach. 

I realize it is just Thursday, but this is a photo just now in the "Wonder Works" parking lot, a very popular attraction.
