Probably they do not want to be answerable to investors they roped in first place with their charm and wild promises of high returns.

Originally you looked at the investment as a risk vs reward and decided to invest.

Airbnb wants hosts to use their service over other platforms and that is why they reward hosts who use Airbnb's own pricing system, smart lock, instant booking, accommodation...

Respect their time by giving them the information they need to include or exclude your listing quickly, and then earn their respect by answering all correspondence quickly.Making life easier for the frazzled person trying to do their job is its own reward.

Risks and rewards to this type of tenant? 

Was the risk worth the reward in your situation?

But again, there is a charm to older properties, because if they do have the proper envelope a great structure, and the ability for a functional layout, they can have a lot of potential. likely a full gut...

If there were no risk there would not be a reward of building wealth.

Risk vs reward.

I definitely agree that rent by the room is awesome for increasing cash flow - again, it does come with it's headaches but with the higher risk comes higher reward (I've been doing it for almost 3 years now, it's really the only way to make the numbers work with little cash down on properties).From my personal experience, talking to others at meetups, and reading this post, I think there's definitely demand for specialized rent by the room property management.
