Diamond D Ranch is a rare opportunity to own a premier 157-acre equestrian estate and professional racehorse training facility in Lone Oak, TX. Designed for serious horse operations, this exceptional property combines extensive training infrastructure with the beauty of East Texas countryside, featuring scenic ponds, mature trees, rolling pastures, & breathtaking views. At the heart of the ranch is a 0.625 mile oval race track, 50 feet wide with fiberglass railings on both the inside and outside, engineered for drainage and raised 14 feet on the south end. Supporting the operation are 2 major training barns totaling over 26,000 SF offering 44 concrete 12 x 12 stalls, tack rooms, vet rooms, wash racks, offices, kitchens, feed & storage rooms, automatic waterers, horse walker areas, & efficiency apartments. The impressive 22,000 SF main barn features 36 concrete stalls, vet lab, therapy room, tack and feed rooms, wash racks, office suites, foreman’s quarters, efficiency apartment, horse walker, round pen, & additional support facilities. Numerous additional barns provide hay & grain storage, maintenance & equipment space, shop areas, vehicle wash facilities, paddock barns, mulch bins, & shaving storage. Housing accommodations include 3 on-site residences, an 8,000 SF dormitory with 10 apartments (8 - 1-bedroom and 2 - 2-bedroom units), plus additional efficiency living quarters throughout the ranch—ideal for trainers, employees, or guests. The property is enhanced by 10 paddocks with sheds, an observation clocking stand, multiple ponds, & over 10 miles of pipe fencing, along with chain-link fencing and numerous gates for efficient ranch management. While this legacy property may benefit from updates and maintenance, its extraordinary scale, infrastructure, and functionality present a truly unmatched opportunity for the racing professional, breeding operation, equestrian training center, or private ranch investor. A Texas horseman’s dream with unlimited potential.
