In addition to their careers in Hollywood, some celebrities are known for building massive wealth through investing in real estate. Some buy homes and flip them to make a big profit. Some rent out their properties. 

The Celebrity Investments Index created a list of top celebrities with impressive real estate portfolios. Here are five who made the list. 

Kylie Jenner

At the age of 21, Kylie became the world's youngest self-made billionaire, mostly due to her cosmetics brand Kylie Cosmetics. However, Kylie has also been investing in numerous real estate properties over the past years. 

In 2017, she sold a Calabasas mansion for $3.15 million, which she bought for $2.5 million two years earlier. In the same year, she sold a house in Hidden Hills for $5.28 million. She bought the house for $4.5 million in 2016. 

Leonardo DiCaprio

Leonardo owns a massive portfolio of multimillion-dollar real estate properties, including the Blackadore Caye, a 104-acre island off the coast of Belize that he bought for $1.75 million in 2015. He later commissioned architect Jason McLennon to design a 68-villa eco-resort on the island. 

Ellen Degeneres

Popular talk show host Ellen has spent at least $145 million buying properties to flip and sell. In 2017, for instance, the "Finding Dory" star bought an estate in California for $7.2 million. Ellen sold it half a year later for a whopping $11 million. 

In 2014, Ellen also bought a $2 million horse ranch that was sold for $15 million on the same year. 

Jay-Z and Beyoncé

Hollywood's power couple have real estate portfolios spanning the continent-from the Hamptons on the East Coast to Los Angeles on the West Coast. Their properties include an $88 million 30,000-square-foot palace in Bel Air and a $26 million seven-bedroom mansion in East Hampton. 

Taylor Swift

Taylor Swift became a multimillion-dollar real estate owner at the age of 20, just four years after she debuted her first album. Today, she is estimated to have $80 million in real estate, the most expensive of which is in TriBeCa, New York, where she bought an entire block for nearly $50 million. 

In 2018, the "Cruel Summer" singer sold one of her homes in Beverly Hills for $2.65 million. She sold the 2,950-square-foot residence six years after she bought it for $1.775 million.
