During prior to the 2008 crisis, one of the shady practices was that all mortgage brokers, realtors and banks were pushing adjustable rates on everyone which was a huge reason so many people lost their homes.
Eventually... But we have to remember that things moved in waves.
2006/2007 was when the foreclosures started happening. Interest rates started going up in that timeframe [0], which lines up with the idea that folks couldn't refinance their ARMs into something they could keep paying on; first due to the higher interest rate, and second because the higher interest rate cause their house values to plummet. As these defaults piled up, in late 2007 and early 2008, the banks who later folded realized that their portfolios were not really salvageable.
I personally think they used this as one of the indicators of "sub-prime" because there were a TON of flippers in ~2004/05 (knew one guy who owned 40 houses with a group of 4 friends)
All APR to keep all the payments lower... they lost them all in 08/09.
