Where do you get stats for short-term rentals? Anecdotally, our last landlady illegally evicted us, converted the house to an airbnb, and then bought the next-door house from the long-time owner to make it an airbnb as well. Not in a vacation town, just downtown in a second-tier city. It seems like a pretty common trend in our neighborhood, I'm wondering if short-term rentals are clustered in dense, walkable areas and the stats are skewed by exurban owner-occupied homes that are 30 minutes drive to everywhere.
It shows that AirBNBs do push up rents - but even in desirable parts of Boston with a lot of AirBNBs - it's /only/ responsible for a 0.4% increase.
Keep in mind that rents have been increasing by >4% per year for 20 years in Boston. A .4% increase is 10% of that. General inflation is /at least/ 50% of it. The other ~40% is coming from elsewhere.
Unless AirBNBs make up a substantial portion of new sales - it is hard to blame them for the majority of price increases.
