I knew anecdotally that most AirBNBs are owned by people who have 10-100 units. The law will restrict people to just their primary home plus one more. So suddenly you’ll have them in some cases selling, in other cases scrambling for renters, in other cases even giving them up to banks or short-selling.
The market seems healthy enough right now that I don’t think it will crash or anything. But we could easily see the past few years of 7% property value growth fall back to 0% or 3%. And very sad for all the jobs lost.
