Zillow Group, Inc. (NASDAQ:Z and ZG) today announced Zillow PreviewSM, a new product that brings pre-market home listings into the open by making them publicly visible on Zillow and Trulia. At a time when some real estate brokerages are harming consumers by hiding listings in private networks, Zillow Preview allows brokerages to broadly share listings before they hit the active market so consumers can access them. It launches next month with initial partners that each align with Zillow's pro-transparency, pro-consumer principles, including large-scale brokerages and franchisors Keller Williams, REMAX, HomeServices of America, Side and United Real Estate. These pre-market listings will be exclusively available on Zillow, Trulia and their own listing brokerage and agent sites.
