Strategic Storage Trust IV Acquires

780-Unit Self Storage Facility Near Tacoma, Wash.

TACOMA, Wash. – (May 23, 2018) – Strategic Storage Trust IV, Inc. (SST IV), a public non-traded real estate investment trust sponsored by SmartStop Asset Management, LLC (SmartStop), announced today its acquisition of a 780-unit self storage facility in the Tacoma suburb of Puyallup, Wash.

“This self storage facility is prominently located between the area’s two primary highway corridors, through which thousands of commuters travel each day,” said Wayne Johnson, chief investment officer. “Adding to its visibility and accessibility, the facility is situated just 200 yards away from a major grocery-anchored retail center. This acquisition is well-aligned with our investment criteria, and we expect it to be an excellent addition to our growing portfolio of self storage assets.”

Located at 1401 N. Meridian Ave., the facility is situated at the corner of the intersection of North Meridian and Highway 167. With approximately 85,000 net rentable square feet, the property features 13 single-story drive up buildings and a two-story leasing office with an onsite manager’s apartment. Constructed in 1990, the facility was 94 percent leased at the time of acquisition.
