In what maybe a first for downtown condo market, there is now a storage space available for sale to highest buyer in the South End. The 21 sq.ft. of storage space with a new plywood floor is asking $18,000. While it’s not unusual for new construction buildings or to offer additional storage for a monthly fee to owners in the building, offering storage to those outside of the building does seem like a first. So the question is, would you pay $857/sq.ft. to store your bikes, golf clubs etc.?
