The housing "bubble" burst in 2006-07, as prices plunged downward in the Sunbelt. Many homeowners could not meet their payments, especially those who had "sub-prime" mortgages because their income was low, or who had adjustable rate mortgages where the monthly payments started small then escalated.  Foreclosures skyrocketed. With housing prices falling few people risked buying a new house (because it would soon be worth less than they paid for it). Construction firms had built millions of new houses that could not be sold but which glitted the market.

The problem was that no one could figure out what CDOs were now worth, so very few were willing to buy them.  One major investment bank, Merrill Lynch, sold its CDOs for 22 cents on the dollar--a "fire sale" price that was less than they were worth in the long run, because in the long run the great majority of people will make their scheduled mortgage payments.
