Real estate markets in California dominate a list of metro areas with the steepest percentage-based decline in home values over the past five years.

Data prepared by online real estate valuation and search company Zillow — based on the company’s home-value estimates and its Zillow Home Value Index, which is generated from those value estimates — reveals that six of the 10 metros with the most severe 5-year fall in value are in California, while two are in Florida and the other markets are in Arizona and Nevada.

The five-year declines in estimated value range from 67.6 percent to 55.6 percent, while the estimated dollar-value declines range from to $382,115 to $125,243.

Methodology: Zillow’s Zestimate home valuations are the basis for the Zillow Home Value Index. A Zestimate is Zillow’s estimate of the current market value for a home. The Zillow Home Value Index is the median Zestimate valuation for a given geographic area on a given day. Zillow generates valuations several times a week on more than 70 million homes, or roughly three out of four homes in the U.S., and calculates historical values dating back to 1997.
