What MGS Group Accomplished in 2025
Our Agency Recaps a Momentous Year in Boston Real Estate
By MGS Group Real Estate
In Greater Boston, the real estate market in 2025 asked for precision, patience, and a team that could understand the market at every level, from in-town condos to legacy estates. As the Family Office in Greater Boston, we advised and brokered deals for over 200 amazing clients, surpassed $600M in total sales, and strengthened our presence across core towns Brookline, Wayland, Wellesley, and Weston — all while giving back over $500,000 to charities and causes close to our hearts.
These 2025 accomplishments reflect a year of extraordinary achievement built on a hands-on approach and investment in longstanding relationships.

Landmark Sales That Led the State, the City, and Weston
High-visibility closings require more than reach, because they demand a process that can anticipate complexity and deliver certainty.
Most noteworthy sales we closed in 2025
-
Top sale in Massachusetts: 41 Cobbs Hill Road, Chilmark — Maggie Gold Seelig (co-exclusive with Brian Doherty).
-
Top sale in Boston: 59 Commonwealth Avenue, Boston — Maggie Gold Seelig.
-
Top sale in Weston: 21 Chestnut Street, Weston — Maggie Gold Seelig.
This is where our team’s negotiation discipline shows up most clearly, and it is also where 2025 accomplishments become concrete through landmark sales.
A Condo Niche With Deep Local Authority
Our agency excels in condos, particularly in Beacon Hill, where we ranked as the #1 Independent Firm for condo sales, and that advantage comes from knowing building-by-building nuance.
Condo milestones that stood out this year
-
Beacon Hill leadership: #1 Independent Firm for condo sales in the neighborhood.
-
South End record-setting closing: 33 Greenwich Park PH, Boston — $4,150,000 (Maggie Gold Seelig, Co-exclusive with Michael Harper).
-
Buyer matching: Targeted outreach based on layout, exposure, and lifestyle fit.
In a condo-centric market, the smallest variables can shape momentum, from elevator access to terrace orientation and the feel of common areas. Our hands-on approach keeps the focus on what truly drives long-term desirability in Boston’s most established neighborhoods.
