Here, courtesy of a longtime high end real estate broker in London, are all the stereotypes you'll ever need to know about wealthy property buyers, by nationality.

Bloomberg Pursuits speaks to Noel de Keyzer, a veteran seller of ultra-expensive London property to ultra-wealthy buyers from around the globe, and gleans the following handy alleged facts, which we, who do not run in these circles, are unable to verify independently:

After 25 years spent selling premium real estate, de Keyzer has become increasingly attuned to the idiosyncrasies of the global wealthy. Middle Eastern buyers won't consider houses without elevators. Singaporeans require lots of staff accommodations. Russians, on the other hand, have few servants and consider privacy and security paramount. Indians like his-and-her walk-in closets. Americans tend to window-shop, preferring to rent for tax purposes.

Legend has it that Andorrans refuse to enter a home that lacks curtains of solid gold.
