The second floor boasts a large primary bedroom with a walk-in closet, an ensuite full bathroom, and direct access to the large, finished bonus space above the garage, currently being used as a home office. Three additional bedrooms and another full bathroom complete the second floor. The finished basement offers additional living space and flexibility, with space currently used as a spare bedroom, while the unfinished section provides excellent storage options. Outside, you'll find a fully fenced backyard featuring a large deck with composite decking that steps down to an expansive patio, a newer swim spa, extensive ambient light setup, a shed for extra storage and ample space for gardening. Additional upgrades and improvements include an upgraded irrigation sprinkler system with digital rain sensors, central A/C, Rinnai on demand hot water heater, generator hookup, security lights and cameras, keyless entry, and a sizeable attached two-car garage.
