36 Vanderbilt Avenue Saint James Colonial in Smithtown Schools, built 1998, on a quiet cul-de-sac. A grand two-story foyer leads to formal living and dining rooms, a fireplace family room, and an eat-in kitchen with granite countertops. Off the rear, a glass-wrapped sunroom overlooks the backyard and opens to a large composite deck. Main level highlights include hardwood floors, powder room, and laundry. Two-car garage with electric-car charger, 9-zone in-ground sprinklers, central air. Upstairs offers four bedrooms and two full baths, including a comfortable primary suite. The walk-out lower level provides flexible space for multigenerational needs, in-laws, or an au pair arrangement: two finished rooms currently set as sleeping areas, a living/rec area with a wet bar, a full bath, and its own washer and dryer, plus a separate entrance. Owned solar panels (2020) help the property generate its own electricity; per seller, PSEG averages about $17/month to keep the account active. East-west orientation, deck and sunroom for everyday enjoyment, and a convenient location near all that Saint James offers.
