The singer reportedly owns two properties in Seoul, and one of them is a mixed-use apartment complex named Brownstone Legend located in Samsung-dong, which he acquired in 2009. The smallest type is about 2,100 square feet and was roughly priced at $1.55 million when he purchased the property 13 years ago. However, the unit is now priced at about $3.35 to $3.77 million, and the same type of flat was sold at $3.35 million in May. Lee Seung Gi also purchased a two-story house last year in Seongbuk-dong, one of the most affluent areas in South Korea. With a land area of about 10,763 square feet and a total floor area of 12,916 square feet, the house was priced at $4.24 million when he acquired the property. The two real estate assets he acquired are now worth more than $7.6 million together. Reports say that he earned money through endorsement deals and TV shows. When his popularity peaked in 2011 and 2012, he reportedly earned $527,128 a year. In 2011, he was rumored to own about $15.1 million worth of assets at the age of 25. The secret to doubling his money was investing. In an episode of a TV show aired last year, he revealed that his parents were bankers, which made him interested in investing at an early age. He said 40 percent of his assets are in his savings accounts, and 20 percent are in real estate. Source (1)
