NAI Hiffman announced the completion of a new 2,748-square-foot lease with Horn-McGowan Insurance Agency at 5500 Pearl Street in Rosemont, Illinois, bringing the four-story office building to 100% occupancy.

The lease follows a multiyear repositioning effort led by ownership, Integris Ventures, and NAI Hiffman. Acquired in 2018 as a value-add investment with 47.7% occupancy, the 136,973-square-foot property has since been fully re-tenanted. NAI Hiffman Executive Vice President Jason Wurtz, Senior Vice President Jack Reardon, and Associate Broker Sarah Walker represented Integris Ventures in the lease transaction and in the broader repositioning and lease-up of the property.

After being engaged by ownership in 2019, NAI Hiffman helped oversee the delivery of a new fitness center, lounge, game room, training room and boardroom, along with upgrades to the building’s common areas. The improvements helped drive more than 66,000 square feet of leasing activity within the first year.
