The house was approximately twenty foot by forty foot and had two stories. There were three rooms on each floor and a covered porch both upstairs and downstairs.Most of McKinney's land and the house were sold to James W. Smith in 1885, Smith's grandchildren granted 682 acres (2.76 km2) to the state of Texas in 1974. It opened as McKinney Falls State Park in 1976. The former homestead was added to the National Register of Historic Places in 1974. It has since been stabilized to prevent further deterioration of the stone structure. The ruins can be accessed via the park's designated "Homestead Trail."
