About This Home

4136 N 21st St

Why rent when you can own, build equity, and create income? This 2/2 duplex offers flexibility for an owner-occupant, multi-generational household, business-minded buyer, or investor. Live in one unit while rental income helps offset expenses, or lease both units and grow your portfolio. The upper unit has been freshly painted and features updated flooring, while the first floor is occupied by a long-term tenant. A fenced backyard, two-car garage with concrete slab, and location just minutes from I-43 add everyday convenience and value.
