Presenting an exceptional opportunity in Chicago's Montclare neighborhood, this fully updated two-unit residential building blends investment stability with modern, luxury living. Originally constructed in 1920, the property has undergone comprehensive renovations including newer kitchens, baths, flooring, paint, and fixtures, resulting in a low effective age of just 20 years and a well-maintained condition across its 2,837 square feet of gross building area. The first-floor main duplex unit features high-end finishes throughout, including exotic rare granite kitchen countertops, marble flooring in the kitchen, dining area, and bathroom, and marble bathroom tile with heated floors. The kitchen is fully equipped with a separate cooktop, oven, warmer, dishwasher, and garbage compactor, offering true chef-quality functionality. The lower-level space is equally upgraded with marble countertops, marble bathroom floors and walls, a luxury shower system with six body sprays, heated floors, and an overhead heat lamp for spa-level comfort. The building is optimally configured to maximize income, featuring a 6-room, 3-bedroom duplex unit and a separate 4-room, 1-bedroom garden unit, generating an estimated total Gross Monthly Market Rent of $3,100, including water and sewer. Tenant comfort is enhanced by central air conditioning, hot water baseboard heat, and a tankless water heater, along with a detached two-car garage and outdoor deck space. The neighborhood offers strong community amenities with access to multiple public and private schools, nearby parks with recreational facilities, library services, medical offices, and religious institutions. Transportation access is excellent with nearby CTA bus routes and convenient proximity to the Metra station. Additionally, this property offers a unique development upside, with the adjacent commercial site available separately, creating a combined contiguous land area of approximately 15,025 square feet with 120 feet of street frontage, ideal for future assemblage opportunities.
