How much is Kwon Sang-woo Worth? Kwon Sang-woo Net Worth in 2026
Kwon Sang-woo’s net worth is estimated at $44 million as of November 2026. Most of it grew out of a self-service car wash. In April 2015 he paid 8 billion won for an old factory site in Seongsu-dong, put a car wash on the ground floor and his agency upstairs, and waited while land prices around it climbed. A February 2025 estimate put the land at more than five times that price.

How much is Kwon Sang-woo worth in 2026?
About $44 million, by our estimate. It is a property fortune with an acting career attached: buildings in Seongsu-dong, Gangseo and Bundang make up nearly all of it. Debt is the hard part, because his buildings were bought largely with bank loans and current balances are not public. We convert won at about 1,340 to the dollar, the rate Trading Economics reported on November 9, 2026.
How we got to $44 million
| Source | Our estimate | What it rests on |
|---|---|---|
| Seongsu-dong site, net of its loan | $28.4 million | Bought April 2015 for 8 billion won, about 5 billion won of it borrowed. Valued at about 43 billion won in February 2025 from nearby sales at 140 million to 162 million won per pyeong. We take off the 5 billion won loan as if still owed: 38 billion won. |
| Deungchon and Bundang buildings, net of loans | $10.8 million | Both valued at 50 billion won or more in a 2023 report. Less the 24 billion won loan on the Deungchon building from 2018, and an assumed 11.5 billion won on Bundang, half its 23 billion won build cost (our assumption): 14.5 billion won. |
| Nonhyeon-dong villa | $3.4 million | His home as of 2023, bought in February 2016 for 3.47 billion won. A unit last traded at 4.6 billion won in October 2021. We assume he still owns it. |
| Gold Coast penthouse | $1.3 million | Bought for 1.7 billion won, reported in 2018. Held at cost. |
| Total | $44 million | Estimate, rounded. Acting savings are assumed to have paid for the Seongsu rebuild, so neither is counted. |
From car wash to Seongsu
The Seongsu-dong lot is 946 square metres, three parcels with two factory buildings when he bought it. Bizhankook reported that he funded the 8 billion won price with about 3 billion won of his own money and roughly 5 billion won from a bank, secured by a mortgage with a ceiling of 6 billion won. He opened the car wash in April 2019, and his company Su Company took the second floor.
In January 2023 the site was on the market at 62 billion won. It did not sell. In October 2024 he demolished the two-storey building and started a new one, due for completion at the end of April 2025, Financial News reported, valuing the land at roughly 43 billion.
Our calculation: the roughly 3 billion won of his own cash that went into Seongsu is now worth about 38 billion won after the loan, close to 13 times the money he put in. That is about $26 million of gain from one decision, more than half his net worth.
A landlord with bank partners
Borrowing is a habit with him. In 2018 his company KGB Film bought a building in Deungchon-dong, a short walk from Jeungmi station, for 28 billion won with a 24 billion won bank loan, Soompi reported. The building came with a monthly rent of 140 million won, a yield of about 6%. Earlier, in 2013, he built a Bundang building for 23 billion won and named it ROOKIEN1129. He also bought a Cheongdam-dong shopping centre for 8 billion won in 2014 and gave it to his wife, the actress Son Tae-young, which is why it is not in our ledger.
Still working
He has kept acting while the buildings did the heavy lifting. According to his Wikipedia biography, he returned as the agent Jun in Hitman 2 in 2025 and plays Choi Seung-min in Heartman: Rock and Love in 2026. His fees for those films were not reported.
Why other estimates disagree
A 2020 television survey put the couple’s real estate at 78.2 billion won, Soompi reported, and higher public estimates often count that total, or the 62 billion won asking price, without the bank debt. Ours counts only what is in his name and subtracts known loans.
What would move the figure
A sale of Seongsu-dong would set a real price, and the gap between the 62 billion won asking price and the 2025 estimate is worth about $14 million. The finished new building on the site should also add value above the land figure, once someone prices it.
