Because the property is so unique pricing likely needs to be as well, maybe consider that based on the property needs/maintenance and location you may not want it consistently turned over so maybe you open 28 day slots and allow use with a 1 time per month turn over.

While all 8 slots are currently filled, one of the selected individual may not be be able to attend. 

I'd like to get other people's opinions but here's what I was thinking on pros and cons.pros: low down-payment, high leverage effectively a hedge against inflation, use up unique fha loan slot, get a second rental, I can get capital gains by building/buying for 5% less than market value. 

If you don’t include utilities in the rent, then do you still need to add a value into those slots ?

This is pretty much what most people do, they use their one and only 2nd home slot for their first STR, then you are stuck with investment loans thereafter. 

I use my extra website slots as testing grounds primarily.

I am going to turn it to gaming parlor and using the slot revenues to generate revenues to achieve the other options I wanted to do in the building.

Either to "free up slots" or take on new loans, private or commercial lending are viable options.  

But so are the mental defectives who buy lottery tickets and pull the handles of slot machines.

It unhinges and the filter goes right at the return register in the ceiling instead of in the slot next to the unit.
