EXECUTIVE SUMMARY

29 S. Webster is an operating office building offering investors upside potential. The 20,766 square-foot property, situated on a 1.02-acre lot, is currently 79% occupied—providing a stabilized cash flow with additional upside through further leasing. Future value may also be realized through potential redevelopment, making this a compelling covered land play in the heart of Downtown Naperville. The property is surrounded by a vibrant mix of retail, dining, and mixed-use developments, along with newly constructed single-family homes priced around $3 million. It benefits from Downtown Naperville’s dynamic environment and excellent foot traffic, highlighted by 102 shopping, 77 dining, and 147 service destinations, as well as close proximity to the Naperville Metra Station. The property offers 85 dedicated on-site parking spaces, a rare amenity in Downtown Naperville. In addition, it is positioned diagonally across from the Paw Paw Lot (119 public parking spaces) and near Downtown Naperville’s 4,000 free public parking spaces. Exceptional demographics, including an average household income of $169,959 and strong projected area growth, further enhance the property’s long-term investment appeal.
