Cattle grazing, dairy farming, and crops of hay and vegetables have been the order of business at this updated 1860s German farmhouse property, designated a “Century Ranch” by the Texas Dept. of Agriculture for its continuous operation by a single family. (Actual reported time of tenancy by the Hillegeist family: more than 130 years.) The Tomball homestead, outbuildings, and pastures occupy 133 acres west of SH 249 near the Oaks of Rosehill area off FM 2920 (which places it about 20 miles west of the new ExxonMobil campus, in case you’re calculating). The property has been on the market since June 2014, for $6.64 million.
