An heiress to the Johnson & Johnson fortune is selling her 600-acre farm for $28.5 million

Elizabeth Ross "Libet" Johnson, a Johnson & Johnson heiress with an appetite for high-end real estate, is selling her Millbrook, New York, horse farm, The Wall Street Journal reported. Set on more than 600 stunning acres of land, Lightning Tree Farm has a private helipad and an 18-stall horse stable. The property is also host to a large main house with nine bedrooms, eight bathrooms, and a movie theater.

Johnson reportedly bought the house in 1980, then over time bought surrounding parcels to assemble the estate as it is today. In addition to this property, Johnson has also listed the 12,111-square-foot townhouse she owns in New York City. Dubbed "The Vanderbilt Mansion" in homage to its former owners, the home is available for rent for $95,000 a month, or $55 million all in, according to the Observer.
