Choi Siwon, a member of Super Junior and an actor, has reportedly earned an estimated profit of 4 billion KRW from a real estate investment made over the last decade.

News1 reported on April 27 that Choi Siwon bought a two-story house near Apgujeong Rodeo Street in Sinsa-dong, Gangnam-gu, Seoul in September 2015 for 1.1 billion KRW under his name. The original house was demolished, and he invested several hundred million KRW to construct a new three-story commercial building now housing a pub, cafe, and office spaces.

As of 2025, the estimated market value of Choi Siwon’s building is approximately 5.4 billion KRW, resulting in an expected profit of about 4 billion KRW after accounting for the total acquisition cost of 1.4 billion KRW, which includes the purchase price and construction expenses.

A representative from Building Road Real Estate informed News1 that properties in the vicinity were sold from 2.12 billion to 3 billion KRW per pyeong (3.3㎡) last year. Based on factors like the building's age, location, and road conditions, Choi Siwon’s building is estimated to be valued at around 2 billion KRW per pyeong. Considering the land size of 27 pyeong, the total value is estimated at about 5.4 billion KRW, leading to a projected profit of around 4 billion KRW over the span of 10 years.

In other news, Choi Siwon's subunit, SUPER JUNIOR-L.S.S., released their new Japanese single "PON PON" on April 18. Additionally, he is actively engaging with fans through the Channel A variety show Heart Pairing and the recently premiered movie "Lobby” on April 2.
