Many of the condos I sell have some strict rules when it comes to #airbnb.
More often than not, the rule book will state that units in the complex cannot be rented out for a period of less than 30 days.
The HOA is trying to prevent the complex from turning into a hotel.
So if you plan to make all this extra cash through airbnb, check the CC&R's first to see if it is even allowed.
