**John M. Corcoran & Co. Closes 2025 with Significant Growth in Management Portfolio**
John M. Corcoran & Co. (JMC), one of New England’s leading residential development and management firms, concluded 2025 with substantial growth in its property management portfolio, adding more than 1,500 apartments under new management agreements. The firm credited this expansion to a combination of new contracts, geographic growth, and strong relationships with ownership partners.
Throughout the year, JMC achieved several major milestones. The company completed new phases of its DUO development in Chelsea and The Devon at Weiss Farm in Stoneham. It also acquired 929 Massachusetts Avenue, a high-rise in Cambridge. In addition, JMC received municipal approvals for a 440-unit project in Beverly and closed a land acquisition deal in Andover at the start of 2026.
“Our momentum heading into 2026 is remarkable,” said Peter Mahoney, Executive Vice President of John M. Corcoran & Co. “With strong owner relationships, expanded geographies and multiple developments underway, JMC is well positioned for continued success in the year ahead.”
Over the past 12 months, five new ownership groups chose JMC to manage their residential communities. Meanwhile, three properties that underwent changes in ownership opted to retain JMC as the property manager—an indicator of the company’s trusted reputation.
Leasing activity was also strong in 2025, with successful lease-ups in Somerset, Stoneham, and Chelsea. Looking ahead, JMC anticipates new lease-ups beginning in 2026 in Pawtucket, Rhode Island, and Portsmouth, New Hampshire.
As the company builds on this upward trajectory, JMC remains committed to delivering high-quality residential communities and expert management across the region.
