Real estate economists Michael Sklarz and Norm Miller, co-founders of Collateral Intelligence, say the widely followed Case-Shiller home price index has exaggerated home price declines for most homeowners.
In a white paper, they argue that the Case-Shiller methodology — which mixes distressed and non-distressed home sales — has overstated price declines in most areas. They also say that as foreclosure sales have increased, the discounts associated with foreclosure prices, historically about 22% below normal market sales, have increased to 25% to 50% in many markets.
The Collateral Intelligence (www.co-intel.com) executives say that because of the widening foreclosure discounts, distressed sales should be examined separately from non-distressed sales when evaluating market conditions and likely future movements in home values.
The Case-Shiller index was created by economists Robert Shiller and Karl Case. The two men could not be reached for comment.
