Storage sale

A New York real estate investment firm that operates a dozen South Carolina self-storage properties has locked up its first purchase in the Charleston region.

A company affiliated with Prime Group Holding acquired Monster Self Storage at 2248 N. Main St. in Summerville earlier this month, Berkeley County land records show. It paid slightly more than $8.03 million for the property, which opened in 2016 near the emerging Nexton and Carnes Crossroads mixed-use developments.

The sellers were affiliates of Carolina Self Storage Centers Inc. of Walterboro and Charleston-based Adams Property Group.

The buyer is headquartered in Saratoga Springs, N.Y. Prime Group's $1.5 billion portfolio is made up of more than 180 self-storage properties with more than 10 million rentable square feet in 23 states.
