Do Zillow.com's estimates violate federal consumer laws?

November 13, 2006
Zillow.com offers free, instant online home valuations ("Zestimates") for more than 67 million houses and condominiums. Launched in February of this year, the site already boasts more than 3 million daily visitors.
     On Zillow, visitors can zoom in on a house, check its value, check out the values of other properties on the same street and neighborhood, and see satellite photos of them all. "Zestimates'' can be found not only on Zillow itself, but also on Yahoo.com and real estate brokerage sites.
