5016 N Mango Avenue Opportunities like this are exceptionally rare. This impeccably maintained Jefferson Park brick two-flat has been lovingly cared for and extensively updated, offering a truly turnkey opportunity for both owner-occupants and investors. Major improvements include a new roof on both the building and garage (2012), updated copper plumbing and electrical service with new panels, remodeled kitchens (2016), all new windows (2017), and a flood control system for added peace of mind. Upgrades continue throughout the property, including fully remodeled bathrooms, luxury vinyl plank flooring on all three levels, recessed lighting, stainless steel appliances, expanded cabinetry, larger bedroom closets, updated light fixtures and ceiling fans, and central A/C added to the second-floor unit. Additional improvements include a new furnace, water heater, and high-efficiency washer and dryer (2018), basement windows, attic access, stair runners, a double-stone patio, and a Trex deck. The first-floor unit lives like a duplex-down, featuring 2 bedrooms and 1 bath on the main level, plus a finished lower-level family room and a versatile bonus room that can easily serve as a third bedroom, office, or gym. Both units offer separate utilities along with central heat and air. Situated on an oversized 30-foot-wide lot, the beautifully landscaped backyard offers multiple entertaining spaces, including two patios, one covered by the garage overhang, along with dedicated garden space. Ideally located near Prussing Elementary, Jefferson Park, the Blue Line, and I-90/94, this move-in-ready property combines exceptional pride of ownership, extensive updates, and long-term value in one of Jefferson Park's most desirable locations.
