The Bevery Hills mansion is nice, but people who never lived in a mansion before, tend to not think about the maintenance required. Not just costs but also time and effort. Not to mention security. A mansion in a country where robbers are packing machine guns is not exactly the definition of safe and secure.
Today, there are so many mansions empty. New ones too, with no one buying. Castles abandoned in Europe, my Manor included.
Today for the truly wealthy, it's all about amenities and size that is managable. And location, location, location. Getting into an Aventador and drive five miles alongside an ocean road to get a carton of milk feels good for the first time but after 500 trips, not anymore.
That's why the HK penthouse costs more, but penthouses in HK or London or New York or Singapore get bought and lived in. Closer to the action. Financial centers of the world. Milk on everystreet. I do not live in a f$%king old manor anymore. And you cannot jump over rooftops in Hong Kong, you would f$%king die from the fall. I take elevators now.
