The Pattons sold the log side of the house on 13 December 1973 to Poco Associates, a partnership composed of the late Mr. Lewis M. Costello and the late Dr. Tunstall C. Powers. Poco Associates continued to rent out the log side of the property just as Miss Grove leased the stone side of the house to tenants during the same period. It was in this period that Ms. Betty Milhon lived in the log side of the duplex. Poco Associates sold the property to the Stone House Foundation in June of 1992.
