Investors from around the world, eager to profit from this steady price climb, bought new investment products tied to mortgages. So many people wanted to invest in these products that, in order to satisfy them, more and more mortgages had to be sold.

Many of these borrowers couldn’t keep up with their payments. When home prices eventually fell, some people found that they owed more on their mortgages than their houses were worth; many responded by stopping
