ewmark has announced the sale of 10 Liberty Square & 12 Post Office Square, a Class B office building in Boston. The team representing the undisclosed seller included Robert Griffin, Edward Maher, Matthew Pullen, James Tribble, Samantha Hallowell, and William Sleeper.

    The 49,725-square-foot property is located within the target area of the City of Boston Planning Department's Downtown Residential Conversion Incentive Program. It features narrow floor plates, operable windows on four sides, two elevator cores, and multiple points of egress, making it well-suited for residential conversion. The building is 53% leased to office and retail tenants.

    According to Hallowell, the property offered an exceptional opportunity to leverage Downtown Boston's Class B office basis reset, presenting irreplaceable urban real estate with tangible upside potential. The central location in Downtown Boston provides access to blue-chip employers, mixed-use developments, public transit options, and regional highways.

    Downtown Boston offers favorable residential market fundamentals, including a single-digit apartment vacancy rate, robust apartment rent growth projections, and strong condominium sale prices, according to Newmark's analysis of CoStar and MLS data. The transaction was supported by Mickey Chapple, Nickolas Revers, and Grady Zink from Newmark's senior financial analyst team.
