Those who refinanced did it at 2%, not 3%, and I would say that their loans were relatively small. These are the ones who bought years ago.
The only ones at risk are the ones who bought after summer 2021. That's when housing price started climbing and mortgage rate started rising as well. At this point, 30-year fixed were around 2.5% already. Those who bought after 2022 were even worse off. I locked in my rate in March 2022, when it was already at 3.25% for jumbo loan. Fortunately, I was able to use bank relation to bring it down to 2.875%.
However, I think even Martin can agree that most of the ones buying after mid/late 2022 were cash buyers or put down 30% to 40%. So I don't think those are at risk.
Again, I would say the percentage of people being forced to sell even with high unemployment is very small. Especially in Irvine and most of OC. You would be a fool if you don't think most Irvine/OC homeowners don't have enough cash to last several YEARs without a job. The fact that 30-40% of these homeowners paid CASH should convince you of that.
