Argosy Real Estate Partners Invests in Middlesex Green in Concord, MA (Boston MSA)

We are pleased to announce that Argosy Real Estate Partners, in partnership with Paradigm Properties, has closed on the off-market recapitalization of Middlesex Green, a four-building, 241,462 sf suburban office campus located in Concord, MA, a northwestern suburb of Boston.

At the time of the recapitalization, the property was 85% leased to a diversified tenant roster with a Weighted Average Lease Term (WALT) of 4.2 years.  The property has historically demonstrated high tenant retention and strong leasing activity due to its high-quality build-out, amenities, and location.  Pending leases are anticipated to bring the property to 89% leased.  The transaction presented an opportunity to invest in a stabilized, well-located office property at a cyclical low for the office sector at a re-set cost basis and execute a lease-up business plan that is significantly de-risked due to the extensive leasing activity achieved prior to closing of the new joint venture.

The property is located five minutes from an interchange on I-95 with proximate access to Route 2 and Route 3, offering tenants both a convenient commute and easy accessibility to nearby amenities in Burlington and Lexington. The property is adjacent to Hanscom Air Force Base and MIT Lincoln Laboratory, which have historically provided steady demand for office space in the area.
