OneKey® MLS Expands Regional Presence With Acquisition of Mid-Hudson MLS

John Jordan • December 8, 2023

FARMINGDALE, NY—OneKey® MLS reported on Dec. 8 its acquisition of Poughkeepsie-based Mid-Hudson MLS, a privately, broker-owned multiple listing service with more than 1,400 agents and approximately 350 offices throughout Dutchess County.

The acquisition brings OneKey® MLS's subscriber base to nearly 50,000 real estate professionals in more than 4,800 participating offices, serving Montauk to Manhattan and north throughout the Hudson Valley. The consolidation is expected to be finalized in January 2024. No financial terms of the transaction were released.

OneKey® MLS CEO Richard Haggerty remarked on the opportunity being presented to agents and consumers alike. “I have tremendous respect for the leadership of Mid-Hudson MLS and all they have achieved over the years. This consolidation makes perfect sense because it expands the reach of listing data to a contiguous geography and benefits our members and consumers who will now have access to a greater pool of information. It should result in time savings for our members as well as consumers,” he said.

“With our operating system due for an upgrade and the challenges facing our industry across the country, the timing of this acquisition works well for us,” said Brian Engles, Executive Officer of Mid-Hudson MLS. “OneKey MLS has a strong agent-centric business model and exemplary operating platform where our brokers and agents alike will benefit from access to the vast and comprehensive listing data offered by OneKey MLS, as well as the many tools which will now be available, including the exposure of their listings on the consumer-facing website, OneKeyMLS.com.”

Agents and brokers of Mid-Hudson MLS, which was formed in 1994, will now have access to a broader pool of comprehensive listing data. In addition, the consolidation will save subscribers time and money by simplifying access to data, removing duplicate MLS memberships and feeds, and eliminating the need to enter and maintain listings in multiple systems.

OneKey® MLS's Board of Managers Chairperson Frank DellAccio said the transaction is a logical step for OneKey MLS as it continues to expand its coverage area to provide innovative solutions for real estate professionals and consumers. “This consolidation is a win-win all around,” DellAccio said. “It is our vision to continuously provide broader and better access to accurate data for our agents, brokers and consumers, for the betterment of the entire industry.”
