Welcome to 263 Thornycroft Avenue, a spacious ranch situated on an oversized 60' x 100' corner lot in desirable Eltingville. Whether you're looking for easy one-level living or the opportunity to expand, this home offers endless potential. The current home features a large living room and dining room with a bay window that fills the space with natural light, an eat-in kitchen with a newer stainless steel stove, three generously sized bedrooms, and a full bathroom with updated plumbing. The full, partially finished basement includes a recreation area with bar, laundry area, and mechanical room. Major updates include newer windows, an updated roof, central air conditioning, forced-air heat, a brand-new HVAC system, and a new hot water heater. A private carport adds convenience yet there is always plenty of street parking available. The 26' x 45' building size and R3A zoning make this property an excellent candidate for a roof raise or second-story addition, similar to homes across the street, creating the potential for a custom home with over 2,000 square feet of living space (consult with architect). Conveniently located on a quiet, tree-lined street just minutes from the Eltingville train station, Richmond Avenue shopping, restaurants, transportation and zoned to highly rated schools. A great opportunity for buyers looking for a move-in-ready ranch today with room to grow tomorrow.
