So many terrifying rock-vs-hard-place counterfactuals in here.
Yan makes $900 a month and a 1100sqft apartment is $300k. If Yan were an American, following the rules and putting down 20% and 25% of his monthly on rent or mortgage, Yan could basically afford a 30-year mortgage on a Volvo station wagon. The down payment alone would take him four and a half years to save up, assuming he could drop a quarter of his paycheck on it.
Some large and terrifying portion of China's wealth is dependent on Yan figuring out a way to afford an apartment five times as expensive as is reasonable. And if Yan can't do it, they're counting on you, by the way - especially if you live on the West Coast of North America.
The hits just keep coming:
That's half of all mortgage debt that is never, ever going to make the money it's supposed to.
If I were the head of the Chinese central bank I suspect I'd hardly be able to sleep. I'd consider putting a bullet in my head.
