alt Hacker NewsPeople say this a lot, but it makes no sense to me. A recession comes with lower incomes and wealth for everyone, so affordability doesn't change for the average person. It only increases it for those who had a short position in their asset allocation, but that's just investment outperformance which you can have even without a recession.
You're generally right except it's not true for everyone. Every recession that hits a lot of folks just keep their jobs and their salaries. Maybe their stock portfolios (for the few who have those outside of 401k's) take a hit. But the key is that if there's a real estate downturn, almost every single home (house, condo and even land) takes a hit and so you end up with a situation where all the inventory drops in price, but not all the eligible buyers "drop in price" (i.e., not all eligible buyers suffer a downturn and so, net, you actually get more people into homes).
The key of course is that the downturn isn't so massive (hello 2008!), where the blood flows so freely that the layoffs/foreclosures/etc. overwhelm the eligible buyer pool in absolute numbers. That can for sure happen, but is atypical historically.
