There is a river of hot water by the hotel Tabacon in San Carlos that is an absolutely unique experience.  

I'm a local Baltimore realtor and I know for a fact that this market is red-hot and everything, and I mean anything, can be sold for the right price.

Do you still have furnace and hot water tank?

I will mention that a hot tub could really increase the frequency of bookings. 

Handyman to wire a hot tub ?   

The "fast turn" metric would suggest that is a hot property. 

This is a hot topic, and something I go back & forth on.

Also, scaling and particularly scaling quickly is capital intensive.

As a sidenote I see people doing this and jacking up the price of the home to seller finance to above market value - if you do this you better be VERY clear with your investors that you are writing a $300k loan on a $250k property as if you do not you can get in some serious hot water later on down the line when doing valuations of the company. 

I was able to replenish emergency fund money I had to dip into for furnishing, was able to pay off a hot tub, was able to replace 2 garage doors and paid for a larger repair this year.
