In the early 1970s, the two homes were combined to make one, and the Hart family bought the property about a decade later. Toni Hart was an evangelist and gospel singer whose family recorded more than 20 gospel albums. Hart purchased the home in 1978 for $190,000. When fires damaged the home in 1980 and again in 1981, Hart and her son decided to enlarge the home, transforming it from 13,000 square feet to its present 31,000 square feet.
The extravagant home features eight bedrooms and thirteen bathrooms. The Grand Party Room can host 400 guests and has a swimming pool at its center. Gold-accented ceilings, crystal chandeliers, and cherubs feature throughout the house.
The home is not only famous for its size and opulent interior but for its guests. Over the years, the Hartland Mansion reportedly hosted any number of famous guests, including Elvis, Frank Sinatra, Marilyn Monroe, Marlene Dietrich, Ronald Reagan, and Liberace. Television shows and movies have been filmed in the mansion, including the film Casino.
Nowadays, the Hartland Mansion functions as a popular venue for weddings and other celebrations.
