Is it possible to find out the price history for a property that's on sale?

Popular real estate website Zillow.com shows price history for most of the properties on sale in its marketplace. Another website that offers price history is MousePrice.com.

Property price history on Zillow.com is pulled from public record, agents and other sources of housing information. The price history is displayed in a table format, with columns for the date of the price, the amount of the price with the percent increase or decrease from the previous price, whether the property was sold or leased, the price per square foot and the source of the information. Users may flag any price history information they find to be incorrect.
