    What's special

    Finished lower levelTimeless curb appealExpansive landscapingMain level laundryLush outdoor entertaining areasGleaming hardwood floorsConvenient half bath
    Welcome to this stunning colonial on one of North Potomac's most beautiful lots, where expansive landscaping, lush outdoor entertaining areas, and timeless curb appeal set the stage for exceptional living! The main level impresses from the moment you enter, with gleaming hardwood floors flowing from the formal living and dining rooms at the front of the home into a warm and inviting eat-in kitchen that opens seamlessly to an additional living area anchored by a cozy fireplace, with a convenient half bath rounding out the floor. Step outside to a covered deck overlooking a gorgeous outdoor garden, an entertainer's dream and a peaceful everyday retreat. Main level laundry adds an extra layer of everyday convenience. Upstairs, the primary suite offers a serene escape with a private ensuite bath, joined by three additional bedrooms and a full bath. The finished lower level is a true bonus, ready for a full kitchen setup with an additional refrigerator, sink, and laundry. This is perfectly suited for multigenerational living, extended guest accommodations, or short-term rental opportunities - with a full bath and a walkout to a deck and backyard. Additional peace of mind comes with a roof replaced just four years ago and a brand-new water heater. Solar panels help to offset utility costs and have a fixed rate for the remainder of their lease. Situated just steps from Aberdeen Local Park on Triple Crown Road, with the scenic 9-mile Muddy Branch Greenway Trail and Seneca Creek State Park just minutes away for hiking, biking, and outdoor adventure. Commuters will love the easy access to I-270, the ICC/MD-200, and the Shady Grove or Rockville Metro Stations, placing Washington D.C. and major employment corridors well within reach. This one is a rare find, don't miss it!
