Exceptional house-hacking and investment opportunity at 3434 N. Nagle Avenue! This meticulously maintained brick bungalow is a legal two-flat offering two spacious, updated residences with separate gas and electric meters. The second-floor apartment features approximately 800 square feet with one bedroom, one full bathroom, a private entrance, and beautifully updated kitchen and bath. The first-floor residence is currently configured as a duplex-down, providing approximately 1,860 square feet with three bedrooms and two full bathrooms across the main and lower levels. Investors will appreciate the property's flexible layout and future potential. Subject to zoning and City of Chicago approval, the finished lower level may offer the opportunity to be separated from the first-floor residence, creating a potential three-unit configuration: an approximately 960-square-foot two-bedroom, one-bath main-floor unit; an approximately 900-square-foot one-bedroom, one-bath garden-level unit; and the existing approximately 800-square-foot one-bedroom, one-bath apartment upstairs. Buyers must perform their own due diligence regarding zoning, permits, and the legality of any future conversion. Live in one residence while renting the other to help offset your mortgage, accommodate extended family with privacy, or add a well-maintained two-flat to your investment portfolio. The brickwork, roof, mechanical systems, interiors, and common areas have all been carefully maintained, reflecting true pride of ownership throughout. Conveniently located on Chicago's Northwest Side near Dunning and Norwood Park, with easy access to O'Hare International Airport, major expressways, public transportation, shopping, restaurants, parks, and surrounding neighborhoods. A versatile, move-in-ready property offering immediate functionality, multiple income possibilities, and outstanding long-term potential.
