The Minnetonka, MN-based buyer acquired the complex, situated at4210-4350 E. Cotton Center Blvd., from two sellers. Opus RealEstate Fund IV of Minneapolis sold the 68,006-sf Building A and57,055-sf Building B while Phoenix-based Opus West Corp. sold the82,825-sf Building C and 57,108-sf Building D. The complex's leadtenants are Aetna Insurance, Genzyme Corp. and Inter-TelTechnologies. The buildings were developed between 2002 and2005.

"These properties came to the stabilization point where Opusthought they'd be good to go," says Brian Ackerman, director withCushman & Wakefield of Arizona Inc. in Phoenix, who led thesales team. He says Carlson's main objective will be to finishleasing and keep the asset for the long haul.

"Carlson ended up being the most qualified because they alreadyown several assets within Cotton Center. These were pretty muchwithin walking distance of the other buildings so Carlson was ableto add more bulk to its portfolio with the buy," Ackerman tellsGlobeSt.com.
