Yeah, but what are the "costs" when AirBnB "moves in?" Expectations of residential building/neighborhood such as certain amount of traffic and noise, as well as neighbors who are relatively long term (in other words, you can get to know them--example may not apply in some cities).

Face it, AirBnB is just the next hiding place for illegal rentals after tax and zoning officials caught on to vrbo. I don't understand how so many people think that they can turn the property under their control (owned or rented) into a business without liability or regulation. Just write the word taxi on your car, pick up some fares, and see what happens.
