A four-building apartment complex near the MGM Casino in downtown Springfield was sold by a Woburn developer for $42.6 million after 28 years of ownership.

The 233-unit Stockbridge Court complex at 35 Willow St. was converted into housing in the late 1970s and had been owned by The Dolben Co. of Woburn since 1994.

The new owner is Stockbridge Ventures, which paid an average of $183,000 per unit for the historic complex.

The property includes a mix of studio, one- and two-bedroom units with average sizes of 720 square feet.

CBRE’s Simon Butler, Biria St. John and John McLaughlin represented the seller, an affiliate of The Dolben Co. and procured the buyer.
