How many acres were there when Jackson bought The Hermitage property and how many are there now?

The Hermitage property which Andrew Jackson bought from Nathaniel Hays on August 23, 1804, for $3,500 was a 425-acre tract of land. The farm would over time grow to over 1,050 acres. Today, the Ladies’ Hermitage Association administers 1120 acres of land as a historic site including almost all of Jackson’s acreage.
