In many parts of the country, home prices doubled during the period from 2000 to 2005. During this same time, creative financing programs (e.g. zero down payment, adjustable rate loans, interest only loans, option ARMs loans, negative amortization loans, etc.) gained popularity and helped some people buy homes who would not normally qualify based on their income, debt level and credit history.
Most real estate markets are now cooling, and some are even experiencing declining prices. In times of dropping real estate prices, the amount owed on a loan by some homeowners may actually exceed the value of a property. If homeowners cannot make their monthly mortgage payment, there is a potential for default on the loan and foreclosure of the property by the lender.
