After the decree of secularization in 1832, when the mission lands and cattle were confiscated, General Jose Castro obtained San Justo Rancho from the Mexican Government.
Francisco P. Pacheco bought the rancho from Castro for the Sum of $1,400.00. In October 1855 Pacheco sold the Rancho to Flint, Bixby and Co., for $25,000.00. Flint Bixby and Co., in turn sold about 21,000 acres to Colonel Hollister. (By this time the Rancho had grown to about 35,000 acres).
