This is the weirdest take on so many levels.
Like, in my filter bubble, I never saw any of that hype/doom. I saw Zillow and a few others making home buying and selling attractive and more efficient because it made the assets much more liquid. One of the most unattractive things to me about real estate was how long it takes to convert it back to cash, compared to other kinds of assets.
The second is that Zillow's $2.8bn position isn't a problem even for Zillow or for the real estate market. There is simply not enough information to suggest its a bust or about the folly of trying to corner a market and there is more information to say that its just reached their corporate risk tolerance. For example, the article doesn't mention anything about the delta between buying price and price they are trying to sell at. Is it 2% off, 5%, 20%? And secondly does it matter? Zillow issued $4bn in corporate bonds at like 2% interest rate to do whatever they want. They've spent half of it on houses and still make revenue. That's nooooooothing like someone overleveraged on a mortgage 20:1. This isn't even 1:1 leverage, its way less. This is a complete nothingburger and that's before we even know the difference in value of their purchase price and new listing price.
$2.8bn or 7,000 homes, is barely a dent in this several dozen trillion market.
"The youth" is still not going to be able to afford anything, no matter if some institutional investors buy this bit, or if there was a fire sale.
