The house you've been waiting for is coming in September. And if a detached North Arlington home on a quiet street, with four finished levels, a flat fenced backyard, and room to actually spread out has been on your wish list, this one is worth the wait. Tucked into the sought-after Madison Manor neighborhood, 6237 12th Street N offers three bedrooms, two full baths, multiple living spaces, and a thoughtfully expanded floor plan that gives you far more space and flexibility than you might expect from the curb. The original home was expanded with a rear addition, creating a larger kitchen and dining area and giving the main level a comfortable flow for everyday living and entertaining. A separate den adds even more flexibility as a home office, playroom, reading room, or whatever extra space your life happens to need. Upstairs, all three bedrooms and a full bath are conveniently located together. Head down one level and you'll find a spacious family room, second full bath, and mudroom, creating a completely separate living area that works equally well for movie nights, guests, a home gym, or simply having another place to escape to. The second lower level provides laundry, utilities, and substantial storage space. One of the home's more unusual features is exterior access from three different levels: the main level, first lower level, and second lower level, making the entire home feel connected to the outdoors. And the backyard is one you'll actually use. Flat, fully fenced, and generously sized, there's plenty of room for dogs, kids, gardening, entertaining, or simply enjoying your own outdoor space. A large shed provides additional storage for bikes, tools, lawn equipment, and all the things you'd rather not keep in the house. Several of the big-ticket items have already been addressed, including two HVAC systems (2016 and 2023), hot water heater (2023), roof (2021), and two chimney rebuilds (2022). The location is another standout. Madison Manor offers the quiet, neighborhood feel North Arlington buyers love, with East Falls Church Metro nearby and easy access to Seven Corners, Falls Church, Ballston, Tysons, and Washington, DC. The home is assigned to the highly regarded Cardinal Elementary, Swanson Middle, and Yorktown High School pyramid. Four levels. Multiple living spaces. A flat fenced yard. A quiet North Arlington street. And a location that makes getting just about anywhere easy. Professional photography and floor plans are coming soon. On the market by Thursday, September 10th.
