Musk, who is worth an estimated 38.9 billion USD added one requirement for the sale of one of his houses. He said he owns Gene Wilder's old house and doesn't want it to be torn down by anyone who'll buy it.

He wrote: "Just one stipulation on sale: I own Gene Wilder’s old house. It cannot be torn down or lose any its soul."
