Robin Williams – $18.1 Million, Napa Valley
Prior to his death, the former actor-comedian, Robin Williams, was able to fully appreciate his large Napa Valley estate of 20,000 square feet in size. It came with a complete vineyard and a farm that had solar power. In 2012, Williams offered the estate for sale as he said it had become too costly for him to keep. The asking price at the time was $35 million. A few months before he passed away in 2014, Williams dropped it to $30 million. Well, the property finally sold in 2016 at $18.1 million, far less than the original price. The world greatly misses Robin Williams.
