I finished the rest of the article. They had the house on the market, but they were able to refinance with a fixed and kept it instead. I wonder if we'll see more of that as fixed rates keep dropping. That could take some supply off the market, and would be bad for the doomsday scenario.
I didn't read the article, but I'm not surprised: they had to eat the prepayment penalty in a refi and now they keep their home.
Next time, they MIGHT read the disclosures.
