Short-term Rentals: Are Small Dipping Pools / Hot Tubs worth the investment?

[Matt Greenfield]

As a homeowner who has never owned a pool or hot tub, I am interested in installing one in the backyard of my short-term rental property. However, I am wary of the maintenance cost and added liability that comes with these amenities. The backyard is on the smaller side, but I think a smaller dipping pool / hot tub would work great. Please keep in mind my market is Charleston, South Carolina which tends to be on the warmer side throughout the year.

Any STR investors who have gone through a pool / hot tub installation, would you mind sharing your experience?

Is a smaller dipping pool worth the investment / added liability? 
Would a hot tub be easier to maintain / more desirable?
Is a pool / hot tub only advisable for short-term rentals? What about furnished "mid-term"?
