Airbnb investment in SF

[Alon Maoz]

Hi there! Relatively new to BP here, so many smart&experienced people here, someone must have a good answer to my question :) I'm thinking of buying a small studio apt in SF for to run as an Airbnb business. What mainly concerns me is the fact that I've heard about a few states (NY as an example) who have banned short term rentals, and the fact that it could possibly happen soon in CA (?), which will force me to long term rent it, which will not make financial sense anymore. Hence, would you think that it would be a risky move to purchase such an Airbnb property in SF then? Thanks in advance for everyone!
