I wonder how much Airbnb is to blame on the raising rents around the world. Why charge a "local" rate when you can charge 5x that rate for a tourist paying in $$$? Even if you don't, just knowing about Airbnb's extremely high prices will most likely put inflationary pressure on rents.
I live in a touristy place in the US, and while STR (short term rentals) clearly don't help, the city's own statistics show they're not a huge factor. More than anything, NIMBY neighbors keep killing less expensive forms of housing... 100's of homes, I would say, in the time since I started observing the situation. STR's make for a convenient bogeyman that people can point their finger at. It's a bit more disturbing…
STRs just slipped past the NIMBYs because they weren't on the lookout for it; it won't happen again!
