Broker Ryan McCarthy of Daniel Flynn & Co. has sold a 1.1 acre retail site at 519-521 Columbian St. The property was sold for $1.28 million. Currently, the property features a 10,000 s/f retail building. The new owners plan to redevelop the building to become Quincy Credit Union's first branch site outside of Quincy. The renovation project will significantly reconfigure the current space and will feature a drive-through. Quincy Credit Union (QCU) CEO Stewart Steele said, "QCU board of directors feel that this new branch will provide added convenience to current members who live or work in the vicinity. Additionally, it is their goal to inform the neighboring communities about the many benefits of belonging to our credit union."
