In my humble opinion there needs to be a sizable income stream bump from the hot tub to justify the aggravation/expense.

After a couple of months - and some bookings and cancellations - I gave it up as way too much effort for a small return.I know it's popular in overseas markets, particularly Europe, so I'm sure there's a market share there but I never needed it (and so far, even though I'm aggravated at AirBNB for how they're handling things, I am staying booked - so far every single day that got cancelled has been rebooked for me).  

But tbh a $100 cash flow in my opinion isn't enough to justify all the paperwork and aggravation unless you're going more for the appreciation factor.

With more than 3 units, this delegation becomes a headache and people can start to get aggravated with each other.

But if I get the sense that you're going to be an aggravating tenant, I'm going to send you on your way. 

Their signature and fee are my authority to do these things.I do other checks, but if the 1st 3 fail, there is not much more that can save them.I loose less money with and empty property than I do after an eviction that goes sour after months of aggravation and no rent payments!

Donkeys and cows might be considered, but cleaning up their "mess" might be a real aggravation:)

I could definitely be running the numbers incorrectly, but for me, making an extra $100 or $200 a month doesn't seem worth the aggravation.  

I should have asked this question months ago, it would have saved me $300 in fees and some aggravation..

Then you won't have to worry about the many burglaries, motor vehicle thefts, assaults, the kidnapping that took place a few streets away, oh and that aggravated robbery that happen just to the south of this property.
