Airbnb will probably continue to work well for vacation rentals although more seem to prefer VRBO. The problem you will see with short term rentals is that some areas are now enforcing or putting new laws on the books to restrict rental turnover to no more than 2 turns a year. We've heard more talk of this lately. I only do shared housing and we've gotten further & avoided problems by just being good neighbors.
If you try to do Airbnb in the suburbs, you're going to have trouble. We have a shared housing home in a $400k neighborhood and have run it for 2 years now without any trouble. Someone else did an Airbnb rental and got an instant cease & desist from the HOA and the community manager. If you do it, you have to very closely screen your users and the amount of traffic. This partiucular home did a thanksgiving rental and the tenants had a dozen people there, with cars everywhere, music and folks outside smoking in the driveway. That was the end of that. Like everything else, you have to be a good neighbor and most folks will work with you. If you in a city environment, it's so busy as long as your renters are quiet....most won't even notice.
In the city of atlanta you have to be very careful not to be running an unlicensed rooming house. All of our renters sign long term, 6-month leases and we have minimal turn-over...our average stay is now 18 months. I would suspect that most major cities address short term, rooming houses in some form or fashion.
