Stunning former model home in sought-after school district in Howard County, Mount Airy! Nestled on a quiet cul-de-sac, this exquisite Avalon model by Ryan Homes was built in 2015 and once served as the community’s model home. Perfectly situated on nearly an acre backing to trees, this property offers a serene and private setting with ample space for recreation and relaxation. Step inside to find soaring ceilings, elegant molding accents, and an open, airy layout designed for both comfort and style. The grand foyer is flanked by formal living and dining rooms, both featuring handsome hardwood floors that extend into the gourmet kitchen and breakfast room. The 2-story family room is a showstopper, boasting a stunning coffered ceiling, recessed lighting, and a dramatic floor-to-ceiling stone fireplace, framed by large windows that flood the space with natural light. Open to the family room, the chef’s kitchen is perfect for entertaining, featuring an expansive island, ample counter space, creamy wood cabinetry, a cooktop, double wall ovens, a large walk-in pantry, and an adjoining mudroom. The sun-drenched breakfast room offers picturesque views and deck access through sliding glass doors. A private home office with double French doors is located on the opposite side of the family room and is currently used as a fifth bedroom. A convenient laundry room and half bath complete the main level. Upstairs, a dual staircase leads to a spacious catwalk overlooking the foyer and family room. The luxurious primary suite rivals any five-star retreat, complete with a sitting area and wet bar, spa-like bath with separate vanities, soaking tub, tiled shower, water closet, and a massive walk-in closet. Three additional generously sized bedrooms with ample closet space share a well-appointed hall bath. The fully finished lower level is an entertainer’s dream, featuring a custom L-shaped wet bar with granite counters, a large open recreation area perfect for billiards, media, and gaming, a walkout sliding door to the backyard, and a full bathroom. An unfinished room provides excellent storage with potential for future expansion. Outside, enjoy the peaceful, tree-lined setting, ideal for pets, play, and outdoor relaxation. Experience the best of quiet country living with easy access to major commuter routes, including I-70 and Routes 27 and 108. Don’t miss this incredible opportunity to own a former model home in one of Howard County’s most desirable locations!

As a licensed real estate brokerage, Estately has access to the same database professional Realtors use: the Multiple Listing Service (or MLS). That means we can display all the properties listed by other member brokerages of the local Association of Realtors—unless the seller has requested that the listing not be published or marketed online.
The MLS is widely considered to be the most authoritative, up-to-date, accurate, and complete source of real estate for-sale in the USA.
Estately updates this data as quickly as possible and shares as much information with our users as allowed by local rules. Estately can also email you updates when new homes come on the market that match your search, change price, or go under contract.
