In its 4th quarter report of 2006, the real estate information site estimates the home value trends for the U.S. and 75 metropolitan areas. According to the data from http://Zillow.com, home values are now declining slightly on a year-over-year basis for the first time in a decade after years of appreciation.

Zillow's home value data goes back to 1997 and reveals the depreciation of home value rates at 0.48 % year-over-year at the national level. The depreciation in home value every quarter is at 4.77 %. Zillow's appreciation rate is based on the value of all homes in an area, including those that were sold.

Although there is a fall in the over-all home price growth, areas such as Seattle and Portland are experiencing a surge in home values at good appreciation rates.
