A Waltham-based development and management company, Marc Resnick and Beantown Properties, purchased the O’Hearn Building at 1444 Dorchester Ave. in Fields Corner last month for $5.6 million under a realty trust that is controlled by Resnick.

The company has a long history of development in Greater Boston, but nothing in Dorchester, according to the company’s website. In March, a broker told the Reporter that the buyer’s offer was chosen from several other offers, mostly because it said it will maintain the continuity of the historical pieces of the building, which houses the United States Postal Service’s 02122 office.

A phone call and email to the new owners were not returned in time for this edition.

The property consists of three parcels – retail spaces, the four-story building, and a parking lot in the back behind that contains the historic Fields House. The space had been on the market for $6.2 million but it was under agreement for the sale price since March.

The late Richie Jerrier owned the building for several years, and his niece, Lisa Theriault, had controlled it since Jerrier passed away a year ago. She was listed as the seller through Jerrier’s estate.

The property has long been a key piece of real estate in Fields Corner, with the post office as an anchor and retail spaces and offices on the second floor. Other floors are largely vacant, and some haven’t been touched since the building served as a warehouse/storage facility.
