I was wondering about that too. In Dublin, which has vaguely similar dynamics (inadequate housing supply, very large presence of tech and other industries which have gone all in on remote-for-now if not remote-forever) rental inventory is up by 60%. Which sounds like a lot, until you look at how tiny it is normally, and how much of what’s showing up to rent is very clearly hastily decommissioned Airbnb stock.

And house prices still haven't started coming down...

They may not for a while. Except for new-builds outside Dublin (or marginally in county Dublin but far from the city) they didn't drop much throughout 2008; sales just slowed down. 2009-2011 was where there was really a big drop.

Airbnb has been heavily regulated in SF for years (ironically), so there hasn’t been a lot of Airbnbs that were full units vs just a spare bedroom in someone’s actual residence.

I see that on LA craigslist. You can find plenty of apartments that come 'fully furnished' with that spartan airbnb black particleboard furniture, cheap tv, and futon. Some of them are only month to month, in anticipation of going back to airbnbing whenever that becomes profitable again, like a lightswitch.
