The folks at real estate website Redfin recently embarked on a fun experiment. They looked at the richest people in America, as ranked by Forbes magazine, and matched them to cities where they could buy all the homes, townhouses and condos.

Lucky for us, none of them is rich enough to buy every non-rental residential property in L.A. (worth $256 billion), but Bel Air's Elon Musk (the Tesla mogul is worth an estimated $8.8 billion) could buy all the homes in West Hollywood, Redfin tells us.

And Steven Spielberg (said to be worth more than $3 billion) could buy …
 … all the homes in the San Gabriel Valley town of Sierra Madre, the site says.

Mark Zuckerberg could afford Palm Springs' real estate, which would cost $13.6 billion, the site says. Investor Warren Buffet could afford both Newport Beach and nearby Coto de Caza, which combined would cost him $40.7 billion, according to Redfin.

Donald Sterling, by the way, could put down $1.9 billion on Randallstown, Maryland, the site says.

Redfin's top cities that billionaires could afford included number 1 Seattle (worth $111.5 billion, affordable for Walmart's Walton family), number 2 Atlanta (worth $78.1 billion, affordable for the industrialist Koch brothers), and number 3 Boston ($76.6 billion, affordable for Bill Gates).

A rep for Redfin told us:

At a staggering $256 billion, the entire city of Los Angeles is too dear for any one billionaire to buy. Some of the most desirable cities in the L.A. area, however, are easily affordable for the wealthiest among us.

We'll take Santa Monica.
