An agent that can structure the deal so it adapts to your strategy and goals.

Adaptability is definitely a key skill required for REI. 

More people cooking/sharing a kitchen, more showers being taken affecting hot water consumption, more persons to occupy one of the couches or tvs, more personalities to adapt with and keep consideration for, etc., plus the utilities you mentioned- water, Wi-Fi, shared amenities such as paper towels and soap etc.I’m not trying to be combative, as your point makes sense.

Whether you air bnb, rent it out (seasonally or year-round), or just own it as a vacation home or part of a timeshare, I'd like to know how your numbers have changed and/or how you've had to adapt. 

But we spelled things out clearly in our transition letter, and with few exceptions everyone quickly adapts.
