People will not sell at a loss bc they locked in to 2% mortgages for 30 years so no
In 08, the poor labor market meant that many people had to sell. That caused prices to drop.
We aren't at that point yet this time, and I don't think anyone knows whether or not we are headed for a seriously rocky job market.
Sellers now with a 2.75% fixed-30 mortgage could trade down a significant amount in housing cost and end up with worse cashflow if they take on a new mortgage at 5+%.
