Airbnb is making this a distinct possibility. I regularly run into people in my small, tourism based town who own 2 or more properties they sit on and rent through airbnb. The most frustrating was a guy who after receiving inheritance is doing exclusively this. Meanwhile the city is spending money buying run down apartments above market rate, competing with these investors who bring little value, to meet the demands of the community to protect the tenants from being forced out.
It is wildly inefficient and would not exist if airbnb followed local laws. If this is allowed to continue, I could easily see airbnb units exceeding the number of hotel units we have in town, where the total number of rooms is nearing 10% of the towns population.
