New York Life Investments has listed One Bowdoin Square, an 11-story office building near Boston’s Government Center, for sale. The 141,800-square-foot property is 73% leased, with tenants including Massachusetts General Hospital-affiliated offices. It last sold for $61.8M in 2016, but experts expect it to trade for around half that amid ongoing office market resets. The listing joins a growing wave of larger Boston office assets hitting the market, as owners and lenders adjust to post-pandemic valuations.
