CHICAGO — Westmount Realty Capital has acquired a 21-building, 2.3 million-square-foot industrial portfolio in the greater Chicago area. Sixteen of the properties are located in close proximity to Chicago O’Hare International Airport and the Illinois International Port District. The other five are situated north of Chicago from Lake County, Ill., to Kenosha, Wis. The portfolio is currently 82 percent occupied. This acquisition brings Westmount’s Chicago area assets to more than 5 million square feet of industrial space. Including this acquisition, Dallas-based Westmount now has nearly 8 million square feet of industrial space in the Midwest region within its portfolio. To accommodate the company’s growth in the region, Westmount will expand its local property management office into a regional office in Chicago.
