People in America” yet?
Surprise, Bill Gates, with a net worth of $81 billion, is ranked No. 1 for the
 23rd year running. Meanwhile, his friend Warren Buffett fell to third place
for the first time in 15 years with a net worth of $65.5 billion.
Thanks to soaring stock prices of hot tech firms, CEOs at the helm of those 
companies seem to have been accumulating wealth at a much faster pace t
han others. Amazon.com CEO Jeff Bezos gained $20 billion to boost his 
net worth to $67 billion, making him the second-richest person in the U.S.
Facebook CEO Mark Zuckerberg jumped into fourth place, his highest rank 
ever, with a net worth of $55.5 billion. However, Oracle founder Larry Ellison landed at No. 5 for the first time since 2007. His net worth is $49.3 billion.
Standing on the No. 6 spot is former New York City Mayor Michael 
Bloomberg, CEO of the eponymous firm Bloomberg L.P., who has a net 
worth of $45 billion.
These six richest multi-billionaires have a combined $363.3 billion at their 
withdrawal, most of which is still held as stakes in the companies they
 founded. However, part of their fortune is vested in real estate. Mr. Gates,
 for one, owns a Washington mansion worth about $170 million, several[
 horse ranches across the U.S. and shares in some luxury hotel chains t
hrough his private investment firm, Cascade.
Here, take a look at the residences the six richest moguls call home:
1. Bill Gates
Worth: $81 billion
Home: Medina, Washington
Mr. Gates, 60, spends most of his time at his 66,000-square-foot Medina, 
Washington, mansion, nicknamed Xanadu 2.0 after the title character’s
 estate in Citizen Kane. The mansion overlooks Lake Washington. 
It took Mr. Gates seven years and $63.2 million to build this house, 
which is filled with lots of high-tech features. He purchased the lot
 for $2 million in 1988, but it’s now worth an estimated $170 million,
 according to public records.
2. Jeff Bezos
Worth: $67 billion
Home: Medina, Washington
Mr. Bezos, 52, in the process of building his e-commerce empire, scooped 
up a vast amount of real properties over the years, earning him the No. 26
 spot on The Land Report’s list of America’s largest landowners last year.
 In terms of residences, he has a 165,000-acre ranch in West Texas, a 
waterfront house in Washington state, three linked apartments in 
Manhattan’s Century Tower, and a 12,000-square-foot Beverly Hills estate 
that boasts Tom Cruise as a neighbor, according to Forbes.
His home at Medina, Washington, close to Amazon’s headquarters, boasts 
5.35 acres and about 29,000 square-foot of living space. Aside from the 
main home, there’s also a caretaker’s cottage and a 4,500-square-foot 
boathouse on Lake Washington.
3. Warren Buffett
Worth: $65.5 billion
Home: Omaha, Nebraska
Although the shrewdest investor on earth holds multiple real estate 
investments, Mr. Buffett, 86, is known for living humbly.
His home sits on a corner in Omaha, Nebraska, which he bought in 1958 
for $31,500. Mr. Buffett has lived there ever since. The house, originally 
built in 1921, underwent several expansions to make it a cozy and comfortable 6,500-square-foot home for the man who has a net worth of over $65.5 billion.
4. Mark Zuckerberg
Worth: $55.5 billion
Home: Palo Alto, California
The youngest richest entrepreneur docks most of his wealth in schools, 
health and other philanthropies. His real estate portfolio include his home 
in Palo Alto and a 9.9-million pied-a-terre near Dolores Park in San Francisco.
Mr. Zuckerberg, 32, purchased his first Craftsman-style 5,000-square-foot 
home in Palo Alto in 2011 for $7 million. He snapped up four of the houses 
surrounding his home in the following years for about $43.8 million to better keep his privacy. But his plan to tear down and rebuild those four homes has been 
stalled.
5. Larry Ellison
Worth: $49.3 billion
Home: Woodside, California
Oracle executive chairman Larry Ellison, 72, has an extensive real estate 
portfolio. He has bought up large parts of whole neighborhoods in Malibu 
and around Lake Tahoe. He owns a $70-million Beechwood Mansion in
 Newport, Rhode Island; a garden villa in Kyoto, Japan; and 98% of the land 
of Lanai, Hawaii’s sixth-largest island, which he purchased in 2012 for $500 
million, according to published reports.
His estate in Woodside, California, with an estimated value of $110 million, 
is modeled after 16th-century Japanese architecture, complete with a 
man-made 2.3-acre lake.

6. Michael Bloomberg
Worth: $45 billion
Home: Manhattan, New York
Former New York City Mayor Michael Bloomberg, 74, has more than a dozen 
of properties worldwide. He spends most of his time at his Upper Estate Side 
townhouse, but he also owns estates in the Hamptons in New York, as well 
as in London, Bermuda, Colorado and Florida.
Mr. Bloomberg’s townhouse, located at 17 East 79th St., spans five stories 
with a limestone exterior. During his three terms as mayor, Mr. Bloomberg l
ived in the townhouse instead of Gracie Mansion. However, he apparently 
has a plan to turn it into a mega-mansion. Since 1989, he has been gradually 
buying up units at 19 East 79th St., the townhouse co-op that’s right next
 door to his current residence. Out of the six units in the white 1880
 Greek-revival-style building, Bloomberg now owns five of them, according 
to The New York Observer.
