That's a scary chart if you ask me. It looks like it's preparing for another dive off the edge into the abyss. Although things are a bit different this time as the FANNIE MAE (https://www.investopedia.com/mortgage/fannie-mae-loans/) projects aren't shilling out money in every direction like they were before the last crisis.

Anyone who's seen or read The Big Short remembers how easily the banks were handing out mortgages for houses at that time. It was like those free cheese stands at the supermarket. Then the banks were packaging the non-performing loans as AAA and selling them to susceptible Scandinavians (among others). There's no way that something of that magnitude will repeat itself, but a similar instance could occur if there are too many empty houses and not enough renters. They're getting ahead of themselves.
