This statement and citation fail to account for the impact of AirBnB and other STR market-makers on the housing market.
I strongly suspect a big part of housing price increases is the "small business" equivalent of institutional investors - someone buys 1-2 units that they do not plan to occupy and rent them as STRs. Similarly, vacation homes (aka homes that will go unused for the vast majority of the time) are now much, much more affordable if you can book a couple rentals a month to supplement a mortgage.
I'm *sure* AirBnb has some fascinating data on this, but I don't expect to ever see it in the public eye without government intervention (much as we'll likely never see Meta's studies on teen users' mental health).
tl;dr - but what about her airbnbs
