About this House

Thoughtfully maintained and located in one of Boulder’s most established and increasingly valuable neighborhoods, this 4-bedroom home in 80304 presents a rare opportunity for long-term ownership in a location surrounded by custom homes, strong appreciation, and enduring demand. Owned by the same family for decades, the property reflects years of consistent care and responsible maintenance. Major updates include Class 4 impact-resistant roof shingles, vinyl windows and sliding patio door, attic insulation upgrades, furnace replacement, sump pump installation, updated flooring, proactive sewer line maintenance, and additional system improvements completed throughout ownership. Rather than an extensively remodeled property, this home offers an exceptional opportunity for buyers seeking future customization, flexibility, or a strategic long-term investment in Boulder. The functional floorplan includes generous living spaces, lower-level recreation and flex areas, an attached garage, mature landscaping, and a private residential setting that provides a strong foundation for future vision and personalization over time. The lower level offers versatile space for recreation, guests, office use, hobbies, or multigenerational living. Ideally located in highly desirable North Boulder near trails, parks, shopping, restaurants, downtown Boulder, and the University of Colorado, the property benefits from both immediate livability and outstanding long-term positioning within one of Boulder’s most sought-after zip codes. The property is currently tenant occupied with a lease in place through January 2027, creating an opportunity for buyers seeking future occupancy, long-term hold potential, or additional planning flexibility while generating income in the interim. A rare chance to secure a well-maintained property with future upside in an increasingly hard-to-enter Boulder market.
