LUXURY PROPERTY AUCTION: 15 OCTOBER-12 NOVEMBER. Current list price reflects the current high bid. Estimated sale price: $1.7M-$2.2M. Nestled along the fertile banks of the Brazos River Valley, Tonk Valley Ranch is a remarkable legacy property that blends natural beauty with the functionality of a working ranch. Carefully stewarded since the early 1990s, this expansive holding showcases rolling native grasslands dotted with magnificent mature live oaks, creating a timeless North Texas landscape. Positioned atop the highest point in the southwest corner, the main residence offers sweeping views of the surrounding countryside and a peaceful sense of seclusion. Designed for cattle operations, the ranch is well equipped with high-quality cross-fencing and abundant surface water. Three well-placed ponds provide reliable runoff capture, including a one-acre lake at full capacity. Beyond its agricultural strengths, Tonk Valley Ranch offers exceptional recreational appeal due to its close proximity to the Brazos River Authority land. With direct access to the river, this property stands out as a versatile investment, equally suited for ranching, recreation, or a private retreat. Tonk Valley Ranch is a true multi-use property, offering both productivity and natural beauty in one exceptional package. A beautifully renovated stone-and-brick ranch-style home offers abundant living space, including a private guest house/game room connected by a charming breezeway. The open-concept layout of the main residence features three living areas, four bedrooms, and four-and-a-half bathrooms. A grand foyer leads into the main living, dining, and a fully updated kitchen with quartz countertops, a large island, new electric appliances, and custom cabinetry; perfect for everyday living and entertaining. Two living areas include wood-burning fireplaces for added warmth and character. Remodeled in 2024, the home features engineered hardwood flooring, updated tile bathrooms, and upgrades throughout, including new lighting, windows, doors, and paint. A spacious mudroom adds storage, new cabinetry, and a washer and dryer. No detail was overlooked in the transformation of Tonk Valley Ranch. Meticulously maintained and thoughtfully upgraded, this exceptional property is truly turnkey and ready to be enjoyed. -- HOME -- Main House ~ Renovated in 2024; 6,602 sq/ft; 4 bdr/4.5 bth Parking ~ Three-car carport, storage under carport Primary Bedroom ~ Large bathroom, three walk-in closets, steam shower, soaking tub, glass shower Secondary Bedrooms ~ In-suite bathrooms, quartz counters Main Living Area ~ Open concept with kitchen and dining area, rock fireplace Kitchen ~ Large quartz island, all quartz countertops, custom cabinets, stainless steel appliances Secondary Living Area ~ Entertaining room with a wet bar, brick fireplace House ~ Central air with a heat pump, new insulation, doors, and windows throughout, professionally cleaned ductwork Driveway ~ Resurfaced asphalt driveway, valued at $73,000 Roof ~ New gutters and downspouts Yard ~ Pipe-fenced yard, newly seeded with an irrigation system -- River -- BRA River Access ~ 1765 feet BRA Land ~ 35 acres Terrain ~ 30 ft of rolling elevation, fertile soil Cover ~ 30% wooded, large pecan trees, oak, willow, and cottonwood -- IMPROVEMENTS -- Utilities ~ Fort Belknap Electric meter, Fort Belknap WSC water meter Road System ~ Dirt ATV roads throughout, good road system throughout Fencing ~ Good to great exterior fencing, cross-fencing in good shape Barn ~ 1,400 sqft, concrete slab, horse stalls, old water hookups Other Improvements ~ Set of cattle pens, covered equipment shed, and loafing shed -- WATER, COVER & TERRAIN -- Surface Water ~ Three ponds, two that hold water well, access to the Brazos River Water ~ Decent underground water in the area Tree Cover ~ Very little tree cover, large mature live oaks Underbrush ~ Minimal underbrush Native Grasses ~ 100% improved or native grass Grazing ~ Currently under AG exempt
