Kylie Jenner – $3.15 Million, California

Most of you first saw Kylie Jenner appear alongside her family on Keeping Up With The Kardashians but these days, Jenner has been making her own mark ever since she started Kylie Cosmetics. With how massive her net worth has been getting, it is easy for Jenner to buy a luxurious mansion at the age of 21.

Jenner once owned a mansion in Calabasas which had six bedrooms, a glam room, an entertainment room, and a huge walk-in closet. She sold the mansion in 2017 for an estimated price of $3.15 million. In 2018, Jenner welcomed her first child, Stormi, with rapper Travis Scott.
