Synergy Investments and a partner firm have refinanced an office building in Boston’s Fort Point district.

Colliers International, Boston’s capital markets group, has secured $37 million in senior financing for 253 Summer St. 

Colliers worked on behalf of Summer/Melcher SPE LLC, a joint venture between Synergy Investments LLC and Independencia S.A., to secure the seven-year, dual-trenched permanent loan through People’s United Bank. 

Loan proceeds were used to refinance existing debt including yield maintenance, plus closing costs related to the transaction and base building improvements. The loan also provided a floating rate instrument to support future leasing activity.

First built as a dry goods warehouse in 1902, the 175,000-square-foot property comprises two integrated buildings – 253 Summer St. and 27 Melcher St. – that function as one asset. The property is currently 100 percent leased to tenants like Neighborhood Health Plan and Skanska USA.
