For most people, they can’t just sell off their homes if they need money, because they still need a place to live, which means they are buying another house at a similar elevated rate.
What that leads to is borrowing money against your house if you want to generate some liquidity out of your house. In addition, most people don’t actually own their homes outright, and have significant mortgages.
A loss of a job, or an unexpected expense, which makes paying back those loans difficult can risk your entire home ownership.
And that’s not even considering a scenario where house prices fall.
Fundamentally, housing is THE most illiquid asset for most Americans. What a lot of Americans have done is traded flexibility today for a potential payoff many years later. At a time with high uncertainty where the flexibility is probably gonna be extremely valuable.
