However, for it to work as a wholesale, one of two things has to happen. 1) get it so far below listed price that there's room to wholesale it or 2) sell it to an out of state investor who isn't on top of all the local listings. 

Would it be wise to install a RING doorbell to monitor who goes in and out of the unit since I would be renting out by room?

I don't know if you're aware but luxury hotel rooms are often super cheap in that country so I'm not sure how you'd compete and make any decent income.

The tenant complained that the A/C was not cool enough in one room.

Hotels typically do this for cost savings, but they also may do this to prevent guests from setting temps that could impact others on a floor or adajacent room (my assumptions). 

(I also do all of the advertising, tours/viewings, communications resulting from the advertising, but once all of the rooms are rented, and I am purely managing, how are property managing hours discerned, I suppose that's my question here.)

I’ve heard for AirBnBs the bathrooms don’t matter much and we plan to put money/ focus into the living room, kitchen and outdoor space.

And you are essentially building an illegal room.

Considering I’ll be living in the house during, it’ll likely be mostly room by room work.
