The home is equipped with 200-amp electrical service, solar panels, and central AC servicing all finished living areas above grade (the basement is not air conditioned), offering efficiency and year-round comfort. A rare opportunity to own a well maintained, energy efficient two-family home in a sought-after Westchester neighborhood.
