Or it could fuel housing bubbles to new heights. The fact that there are now housing lenders who use projected AirBNB revenues in determining creditworthiness is worrying.
If the property is more valuable there is no bubble. I do agree some lenders might get this wrong, but an overall increase is pretty reasonable I think.
Counting it as just straight up income is not correct, though, given that AirBNB is essentially the hospitality business, which is highly cyclical. The first thing people cut back on is traveling, and hotels are not afraid to race to the bottom to fill rooms.
