A federal judge in Newark has tossed a property owner’s lawsuit claiming real estate website Zillow violates antitrust law by making deals with some companies to hide its property value estimates.

The plaintiff, who was attempting to sell an eight-bedroom house in Cresskill, New Jersey, with Manhattan views for $7 million, said in the suit that buyers were put off by Zillow’s $3.3 million estimate of the property’s fair market value, displayed next to the list price. The company’s approximations of market value, calculated by an algorithm based on publicly available data, are called Zestimates.
