The “South Barrington Office Center” (property) presents investors with the opportunity to acquire a well-stabilized, cash-flowing, single-story suburban office portfolio in one of Chicago’s most affluent northwest communities. The property is comprised of ten single-story buildings totaling 108,340 square feet across 63 individual suites, situated on 10.87 acres of land fronting Higgins Road, with direct line-of-sight visibility to Interstate 90, which sees over 100,000 cars per day. The investment opportunity is currently ninety-four (94%) percent leased to a diverse mix of medical, professional, and service-oriented tenants, offering a durable income stream with tenants committed until 2027 at the earliest. Listed at $9,900,000 ($91 PSF), the investment provides an attractive 9.40% going-in cap rate and a 10.16% leveraged cash-on-cash return based on a yearly (12-month forward) NOI of $930,280. Conservative financing assumptions with a 65 percent loan-to-value ratio and a 1.71x DSCR further strengthen the property’s stable cash flow profile. The current rent roll demonstrates consistent tenant demand and retention, supported by recent leasing success and well-balanced lease expirations. The property has seen exceptional leasing activity in 2024 and 2025, with 24 new leases signed since March 2024 and 8 renewals since June 2024, reflecting robust demand for well-located, affordable suburban office space. Average rents on new leases are $18.50 per square foot, indicating substantial room for rent growth. Base-year stops in leases protect new ownership from expense increases moving forward. Positioned just west of The Arboretum of South Barrington, a premier open-air lifestyle center with upscale retail, dining, and entertainment, the property benefits from strong regional traffic, affluent demographics, and convenient access to Route 59, Barrington Road, and Interstate 90. Located in a fantastic, affluent area, South Barrington Office Center offers investors an opportunity to acquire a proven, income-producing suburban office asset with both strong in-place returns and long-term upside potential through rental increases and the addition of medical office tenants.
