Who knows what material and chemicals they used to remodel their airbnb.
I can understand someone Airbnb'ing a room in their house or Airbnb'ing their vacation home when they're not there. But buying a house that is only used for Airbnb is really a violation of the terms.
It's one thing if the Airbnb property is in a location like a vacation spot where none of the residents are permanent, but many of these properties are located in neighborhoods where a constant stream of different renters is not appreciated.
