10001 W. Roosevelt Road presents a compelling value-add investment opportunity to acquire a 48,000 SF multi-story commercial building with Industrial (I) zoning in the heart of Westchester, Illinois. The property offers a rare combination of office, medical, and industrial-flex usability, significant vacancy upside, and strong long-term positioning along the Roosevelt Road corridor. With approximately 16,000 SF per floor across three stories and a highly divisible layout, the building supports a wide range of suite sizes and tenant uses. The Industrial (I) zoning provides flexibility for office, medical, warehouse, flex, and light industrial uses, enhancing exit optionality and reducing leasing risk compared to office-only assets. The property benefits from excellent frontage and visibility on Roosevelt Road (Route 38) and convenient access to Mannheim Road, I-290, I-294, and I-55, making it attractive to both local and regional tenants. On-site parking and flexible floor plates further support tenant demand across multiple use types. At stabilization, the asset is well-positioned to deliver strong yield on cost, with conservative underwriting assumptions pointing to meaningful upside through vacancy burn-off, rent growth, and expense optimization. The combination of discounted basis, flexible zoning, and extreme vacancy makes this opportunity ideal for value-add investors, owner-users, or operators specializing in repositioning underperforming commercial assets.
