Signs are multiplying that the US housing bubble is about to pop. To start with the headline number, home sales are back at Great Recession levels:

Declining sales are no surprise when viewed against a backdrop of the worst affordability in American housing history. The following chart explains why Boomers are such a cocky generation: We grew up in a time when pretty much everyone could afford a decent house. Now, the average person can’t come close to affording the average house:

Normal topping behavior

Sales falling while prices are reasonably stable is actually normal for housing market tops. Sellers demand the prices they saw a year ago, and buyers can’t afford to pay that much, so the number of completed sales shrinks. Observers start referring to a “sellers’ strike”.

The idea takes hold that these assets will always go up — right before they crash.

And Airbnb might be the catalyst for the 2024 bust:
