Welcome to this beautifully updated, move-in ready home at 4277 Wilson Ave in the desirable Plum Grove Countryside subdivision of Rolling Meadows-where classic charm meets extensive modern upgrades! Built in 1965, this meticulously maintained residence has been thoughtfully improved over the years. The kitchen was fully remodeled in 2021, featuring new plumbing, cabinetry, stainless steel Samsung appliances-including oven/convection range, microwave/warming drawer, refrigerator and dishwasher-and luxury vinyl flooring that extends throughout the first floor. Enjoy cozy evenings by the wood-burning fireplace in the living room. The home's bathrooms have all been renovated: the two full bathrooms were fully remodeled in 2020, including raised ceilings and conversion of the lower-level tub into a stylish shower, while the powder room was fully updated with a new ceiling, walls, vanity and toilet in 2022. Additional interior upgrades include professionally painted living spaces (2022), a re-plastered living room ceiling, and all-new solid white interior doors. The staircase was completely rebuilt-brought up to code, reinforced, and finished with new steps and railings-and hardwood flooring was added to the upstairs hallway. The finished basement (2025) provides valuable additional living space with extensive improvements including reframing, drywall, and new LVT flooring. The layout was enhanced by removing the wall between the laundry and storage areas for improved flow and functionality, and equipped with an LG washer and dryer. Major systems have been updated for comfort and efficiency, including a newer HVAC system (2022) with Carrier forced-air heating, central A/C, a whole house fan, and a sump pump with new battery and backup system (2025). The exterior features durable vinyl siding and enhanced curb appeal with updated window configurations-including a bay window and enlarged front window. The wooden fenced yard includes a gate added in 2015, with additional exterior updates such as newly installed coach lights and freshly sanded and stained deck (2026). The concrete driveway and garage floor were newly replaced and raised in 2024-2025, and the attached two-car garage includes a new high-quality door and opener along with two transmitters (2025). This home offers a blend of comprehensive updates and functional living spaces and is located right off of Hwy 53 for easy access to I-90, and is less than a 10 minute drive to the Arlington Park and Arlington Heights Metra train stations, downtown Arlington Heights, Woodfield Mall, and is located in the highly sought after Fremd High School District!
