4125 N Keystone Ave

A mid-rise condominium building in Chicago’s Old Irving Park neighborhood, built in 1974 and rising six stories. The property is accessed by an elevator and is configured primarily as residential condominium units, many offering one to two bedroom layouts with balconies and city or tree‑lined street views. Common interior features include concrete floors in parts of the structure, built‑in cabinetry, and dedicated storage rooms; laundry facilities and additional storage are located on the main floor. Exterior traits emphasize modest urban living: private balconies accessed through sliding glass doors, door monitoring via TV, and a landscaped streetscape that faces residential Irving Park avenues. On-site parking is a notable convenience—deeded detached or heated garage spaces are associated with many units, sometimes large enough to accommodate more than one car. The building’s maintenance profile reflects periodic updates: replacement windows and patio doors, refreshed common areas, and unit renovations seen across listings (kitchens and baths updated at different times). Pets are permitted with weight restrictions. Located within easy walking distance of the CTA Blue Line and Metra, and with direct access to I-90/94, the address suits commuters and those who favor neighborhood restaurants, parks, and local retail. The overall character is practical, community-oriented condominium living with a mix of move-in-ready and as-is resale opportunities.
