About this home
Rare opportunity to own a large (16,675st ft) usable Mid-Island property. Bring your contractor, builder, designer and some vision to imagine what could be done here. Situated on a corner lot with circular driveway, this property feels like you are miles away from the city because of the privacy of the mature landscaping. Fabulous near level yard for anyone who enjoys being outside. Walk to elementary and high school, the Boys & Girls Club, the swimming pool, library, chruches and more. This 1950's home is in need of some upgrades and maintnance. Tons of potential or if you prefer to design and build a custom home, this property is worth considering because of the great location. Living room has large picture windows looking out at the yard with a peek view of the Olympic Mts. The kitchen has a good amount of counter space and an eating area that can be expanded when a larger space is needed. There is a deck to the large deck off the dining area making it convenient when you want to BBQ or dine outside. There are three bedrooms on the main floor, including the primary badrrom with 3/4 bath. Two the the bedrooms have access to a westerly facing deck. The lower level has a spacious rec room with fireplace. There is a den on the lower floor and a 3/4 bath. Part of the basement is unfinished with some shelves. This area is great for storage or finish the space for your own use. There is a 2 car carport and substantial additional parking for 4+ more vehicles or an RV.
