3 Cornelius Avenue, Niskayuna, NY 12309

Welcome to 3 Cornelius Avenue, where classic character, thoughtful updates and generous outdoor space come together in the highly sought after Niskayuna School District. With Hillside elementary school located at the end of the street, this four bedroom home also offers a dedicated den or office, providing the flexibility today's buyers are looking for. Inside, original built-ins, detailed trim and warm hardwood floors preserve the home's timeless appeal. The kitchen has been tastefully updated with granite countertops, a tile backsplash and tile flooring, adding modern function while honoring the charm of the home. Upstairs hardwood floors were beautifully refinished in 2025, and the remodeled bathroom features ceramic tile, crisp white wainscoting and chair-rail detailing, along with updated plumbing and electrical completed in 2025. Step outside to a spacious rear deck overlooking a peaceful, fully fenced double lot bordered by a classic white picket fence with two convenient gates. A long lolli-pop brick-paved driveway with a turnaround leads to the detached one-car garage with access from both sides. Vinyl siding, an exceptionally clean basement with concrete floors and valuable improvements, including roofs on the home and garage in 2021, gutters in 2022 and spray-foam attic insulation in 2026, all add to the home's appeal. Filled with personality and lovingly maintained, this is more than a house, it is a cherished home ready for its next chapter.
