How Much are Home Prices Dropping?

It depends on the indicator you're looking at, NAR Research says. Among the main indicators are those provided by NAR, Freddie Mac, the Federal Housing Finance Agency (Formerly OFHEO), and Case-Schiller. Each one is different because it looks at different data sets and uses different assumptions. An explanation of the differences, which will help you interpret news and other reports on home price trends, is available online from NAR.
