The White House, which has housed US presidents and their families since 1800.
Despite the presumption, the 55,000-square-foot mansion at 1600 Pennsylvania Avenue, NW is not for sale.
“This would be an extreme luxury home,” the Jason Koitz, a strategist with The Koitz Group, was quoted as telling real estate website Movoto.
“It would probably be $100 or 115 million,” he said.
Koitz said that his estimate reflects comparable sales in the Washington area, where the most expensive home, a 21,000-square-foot mansion in McLean, has an estimated value of $45.5 million (Rs 243 crore).
The house has been renovated nine times in its 212-year history.
Koitz said the White House could sell for as much as a billion dollars, after factoring in the dwelling’s historical value.
The process “to see what it could potentially fetch, would be astounding,” he added.
