The real-life Gatsby estate and mansion is for sale. Which is to say that the former Long Island home of railroad heiress Mary Harriman Rumsey is on the market. Rumsey was a friend of the author of The Great Gatsby, F Scott Fitzgerald, and it is generally accepted that the writer based the palatial home of Jay Gatsby on Rumsey’s Normandy- style house at 235 Middle Neck Road. Sands Point, New York. So if you fancy an 11,955 square-foot American home complete with 13 bedrooms and 8.5 bathrooms, and have $I6,880,000 to spare you might even snap yourself a bargain; the price has dropped 15% since September. The estate includes five acres of land, a private beach, caretaker’s cottage, guest house, boathouse, tennis court and swimming pool.
