About This Property

Beautifully maintained home featuring a thoughtful 2005 renovation that enhanced the upper-level bedroom spaces. The spacious primary bedroom is conveniently located on the main level and features French doors opening to an expansive 20' x 18' deck overlooking a 20' x 13' above-ground pool.

The inviting front entry showcases a slate floor and a dramatic two-story foyer. Red oak flooring extends from the primary bedroom through the main living areas, including the living room with a cozy fireplace. The open-concept kitchen offers Silestone countertops and a full suite of high-end stainless steel matching appliances.

A formal dining room features wood-look porcelain tile flooring, a bow window overlooking the large PVC-fenced backyard, and sliding glass doors providing direct access to the deck.

Additional highlights include a detached two-car garage with a remote-controlled double-width garage door, a finished basement with a large closet, a separate laundry room with washer and dryer area, and Bilco doors for convenient exterior access.

Major updates include a roof installed in 2010 and a cesspool replaced in the early 2000s.
