A truly rare chance to own on one of Jefferson Park's most tightly held blocks. This custom-built 3-bedroom, 1-bath step ranch has been lovingly held by the original owner and is now ready for its next chapter. Inside, this custom-built step ranch features a hard-to-find open-concept layout with a mid-century modern feel. The living room, dining area, and remodeled kitchen with eat-in bar flow together beautifully - an unexpected and valuable feature for a 3-bedroom step ranch. It creates a comfortable, connected space for everyday living, hosting, and entertaining. Hardwood floors run throughout the entire first floor and were refinished in 2016. The remodeled kitchen was completed around 2015-2016, and the home has had several major improvements over the years, including copper pipes replaced in 2019, a new HVAC system in 2022, and chimney tuck pointed in 2026. The basement is a standout feature, with approximately 8 ft ceilings and framing already in place, making it ready for your ideas. Whether used for a recreation room, home gym, storage, workshop, or future finished living area, the lower level adds valuable flexibility. Located in the desirable Jefferson Park Pocket, this home sits directly across from a beautifully updated Chicago Park District park, giving the 4800 block of Gunnison the feeling of having its own private green space. Opportunities on this block do not come around often. The low-maintenance backyard is for easy outdoor living and entertaining, complete with a natural gas line run to the backyard grill - no more running out of propane during a cookout. One of the standout features is the heated and air-conditioned two-car garage with an extension, built by the original homeowner, a mechanic who built race cars for NASCAR. Great for the handyman, crafter, small business owner, entrepreneur, hobbyist, or making it a mega man cave neighborhood tavern, this is for you. The location is ideal - just a short walk to the Blue Line, Metra, parks, shopping, restaurants, and neighborhood conveniences, with easy access to I-90 and I-94. Property is being sold as is. Best final coming soon.
