Great opportunity to own a mixed-use building in the heart of downtown Crystal Lake! The street-level storefront offers excellent visibility, strong foot traffic, and a walkable location surrounded by popular shops, restaurants, and community events. An attractive setup for long-term commercial tenancy. The second floor features a 2-bedroom residential unit, providing an additional income stream or flexibility for an owner-occupant. With both spaces available, investors have the ability to lease at market rates or tailor the property to fit their investment strategy. A solid opportunity in one of Crystal Lake's most active and desirable downtown areas with strong long-term potential.
