It's sad to hear, but I'm not so sure it's inspirational qualities are enough to fork out $4,500 a month for upkeep of the 1902 estate. According to Time.com, the estate is worth $30 million and will be replaced by five custom homes running about $10 million each.
An excerpt from the article: Current owner David Brodsky has some doubts as to whether Fitzgerald was ever actually on the estate. "To be honest with you there isn't anything really special about it," Brodsky told the New York Post. "We did a lot of research on its history and there is really no evidence that Fitzgerald was even ever there."
I'd be more interested in the home Fitzgerald owned, which still stands in Great Neck.
