4 Mainstay Lane Enjoy Bourne Bridge views and nightly sunsets from this beautiful 4-bedroom, 3.5 bath ranch with a partially finished walkout lower level. Set at the end of a cul-de-sac in the exceptionally private Port of Call neighborhood, perfect for dog walks and easy jogs.

The kitchen has maple cabinetry and a second prep counter with a sink. Off the garage entry, a convenient laundry room with a deep pantry and two closets, and a flexible back room for office, den, or storage. The dining area connects to a low-maintenance Trex deck, a natural spot for a drink with friends, enjoying the breathtaking sunset colors. The main level includes a primary suite with a walk-in closet and an updated tile bath, two additional bedrooms with a full hall bath, and a half bath. The walkout lower level adds a family room, a full bath, a fourth bedroom with a walk-in closet, and ample storage.
