Here is an interesting tidbit:
$100M Calif. mansion has unusual sale requirement.
HILLSBOROUGH, Calif. (AP) — As if the $100 million asking price wasn't deterrent enough, the owner of a mansion for sale in a ritzy San Francisco suburb says the buyer can move in only after his death.
That is indeed a highly unusual requirement. Why would anyone buy a house that he could inhabit only after he was dead? And why would he need a mansion for such necrotic tenancy?
