There are times when the economy is brisk and everyone feels confident about his or her prospects for the future. As a result, they spend money. People eat out more, buy new cars, and...they buy new homes.

Then, for one reason or another, the economy slows down. Companies lay off employees and consumers are more careful about where they spend money, perhaps saving more than usual. As a result, the economy decelerates even further. If it slows enough, we have a recession. During such a time, fewer people are buying homes. Even so, some homeowners find themselves in a situation where they must sell. Families grow beyond the capacity of the home, employees get relocated, and some may even find themselves unable to make their mortgage payment - perhaps because of a layoff in the family.
