371,805 acres (up 109,000 acres)
The Texas homebuilder acquired new lands in the Southwest, snapping up New Mexico’s 109,000-acre Double V Ranch in Chaves and DeBaca Counties. Formerly owned by Richard Evans, the Double V fell victim to the worst drought in more than a century. In 2014, Horton added the Great Western Ranch to his holdings, which also include Camp Horton, an 86,000-acre ranch in West Texas.
