The multiple listing service, formed after a merger of Hudson Gateway MLS and Long Island MLS, claims it has more than 42,000 subscribers and 47,000 listings.

The New York Multiple Listing Service (MLS), born out of a 2018 merger between the Hudson Gateway Multiple Listing Service and the Multiple Listing Service of Long Island, is rebranding as OneKey MLS.

“When we partnered with [Long Island Board of Realtors], we set out to expand the size and scale of an MLS to create greater opportunities for our members,” said Richard Haggerty, president of OneKey MLS and CEO of Hudson Gateway Association of Realtors.

“Until now, real estate professionals in New York City had to use different platforms and websites to market or find listings,” Haggerty added. “With OneKey MLS, everything they need is in one place. We believe that the listing service will grow to become the most trusted data source in the New York City residential market, for both professionals and consumers.”

Boroughs in New York City have multiple listing services, but this is the first one that says it covers all of New York City. Staten Island and Brooklyn have their own MLSs and Queens listings previously appeared on MLSLI. OneKey describes itself as the first Realtor-run MLS in New York City.

The Real Estate Board of New York (REBNY) currently has a listing service, but it’s not public-facing. The Residential Listing Service sends its listings to, RentHop and — but not StreetEasy.

StreetEasy, a public-facing real estate listing portal owned by Zillow, has long acted as a de facto MLS for New York City, with brokerages sending listings directly to StreetEast.

OneKey MLS, which claims to have more than 42,000 subscribers and 47,000 listings, will offer real estate agents and their clients access to listings from the tip of Long Island to the Catskill Mountains in New York State. Subscribers can create a profile for clients and invite them to share and view recommended properties.

“We are the one regional MLS that covers more territory with more listings, providing subscribers more ways to achieve success,” Jim Speer, CEO of OneKey MLS, said in a statement.

Adoption will be key for the still-nascent MLS. Compass gave OneKey MLS a boost last year when it announced it would send listings directly to the MLS. 

Outside of New York City, however, the MLS has a number of brokerages involved. Its board of managers includes leaders from franchisees of Better Homes and Gardens Real Estate, Century 21 and Keller Williams, as well as Houlihan Lawrence, one of the top brokerages in Westchester County.
