Welcome to this well-kept center-hall Colonial located in the heart of Islip. The home offers a traditional layout across three levels, along with meaningful system upgrades and an oversized detached garage ideal for car enthusiasts or anyone in need of substantial workspace. The first floor features a comfortable living room, a dining area, and a newly renovated kitchen with modern finishes. A full bath and dedicated laundry area complete this level. Upstairs, you'll find three bedrooms, including access to a Jack-and-Jill style primary bath. The mechanicals have been thoughtfully updated: a new Weil-McLain gas furnace and hot water heater, upgraded 200-amp electric service, and connection to the public sewer system. The roof is approximately five years old and is complemented by owned solar panels (not leased), providing long-term energy efficiency. The lower level offers a full basement, adding valuable storage and flexibility. Outdoors, the property includes an oversized detached garage with an extra-tall overhead door-perfect for collectors, hobbyists, or commercial-grade vehicle needs. The expansive backyard presents the option to add a pool, offering flexibility for future outdoor amenities. A deck, front porch, and large yard complete the exterior offerings. A well-maintained home with solid improvements already in place, ready for its next chapter.
