#6 Sergey Brin's exquisite West Village apartment

Estimated home value: $13 million

Title: Co-founder, Google

Brin bought four-bedroom penthouse with a 23-foot balcony in 2008 for $8.5 million. One of the most extravagant features in the West Village apartment may be the limestone bath, which comes equipped with heated floors.

"With just five 'neighbors' in the building, and being the penthouse of a relatively new structure on one of the West Village’s hottest blocks, Brin’s apartment, it is likely worth more than $13 million," said Nick Jabbour, Senior Vice President at Nest Seekers International. "The tech industry has really embraced the West Village and Chelsea, and executives within the tech sector have taken a part in the skyrocketing values of these neighborhoods."

Brin reportedly also owns a $7 million property in Los Altos Hills, Calif.
