This is a total hypothetical. The White House is not for sale. However, if it were, it would be valued at about $398 million.
According to Zillow, that would be the price tag of the 55,000 square foot home with 16 bedrooms, 35 bathrooms, a gym, a pool, a tennis court, a movie theater, a library, a bowling alley, and a game room.
Plus, it's got a pretty great home security system.
