US listings service Zillow has started listing pre-market homes to the platform with a product called Zillow Preview.
Launching next month, this allows brokerages to share listings before they hit the active market.
Large-scale brokerages and franchisors on board include 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.
Jeremy Wacksman, chief executive of Zillow, said: “For 20 years, Zillow has been guided by a simple idea: Real estate works best when information is open and accessible.
“No one should have to obligate themselves to an agent from a specific brokerage just to know the full breadth of inventory available.
“Zillow Preview shines a light on listings that might otherwise stay hidden, giving buyers open access to their options and sellers the broad exposure they deserve.”
Zillow is the most visited real estate marketplace in the United States, reaching an average of 235 million unique users each month.
Gary Keller, executive chairman and co-founder, Keller Williams, said: “As an independent company, we support efforts that make the real estate marketplace more transparent.
“Ensuring that consumers, our franchisees, and agents have meaningful choice will always guide our approach.”
