Description
Welcome to this inviting 3-bedroom, 2-bath ranch in Ronkonkoma, offering a thoughtful combination of recent improvements, everyday comfort, and practical living spaces. The beautifully renovated kitchen, updated within the past two years, serves as a welcoming centerpiece of the home, offering a refreshed space for relaxing, cooking, and gathering. The convenient ranch-style layout is complemented by a full finished basement with a separate walk-out entrance, providing additional space and flexibility. Notable improvements include a roof replaced in 2019, a 200-amp electrical panel, and an oil burner and hot water tank approximately five years old. Four-zone oil-fired baseboard heating and ductless air conditioning units installed approximately six years ago provide options for year-round temperature control. Outside, a five-zone in-ground sprinkler system services both the front and rear yards. Additional features include kitchen appliances approximately six years old and a washer and dryer replaced approximately three years ago. Conveniently situated just minutes from the Ronkonkoma Long Island Rail Road station, this property offers access to regional transportation. With its combination of recent updates, functional features, and convenient location, this ranch presents an opportunity to enjoy all that the property has to offer.
