Actor Seo Kang-joon has quietly made a massive real-estate profit—earning approximately ₩2.41 billion (about $1.7 million USD) after selling his high-end apartment in Seoul’s trendy Seongsu-dong.
According to real-estate industry officials on November 14, the 32-year-old actor sold his Trimage (트리마제) apartment—140.3㎡ (about 1,500 sq ft)—for ₩5.8 billion this June. He originally purchased the unit for ₩3.39 billion in December 2019, meaning the property’s value rose over 70% in just five years.
His agency, Man of Creation, simply stated:
“This is a private matter, so we cannot comment.”
This isn’t his first successful property move
Seo Kang-joon previously owned another Trimage unit.
- 2017: Bought a 136㎡ apartment for ₩1.64 billion
- 2019: Sold it for ₩2.9 billion, then immediately purchased the larger unit he just sold
This means he has now made two profitable real-estate flips in the same luxury complex—one of Seoul’s most celebrity-packed buildings, often referred to as the “K-pop idol apartment.”
Records also show that when he bought the second unit in 2019, around ₩1.5 billion was likely financed through a mortgage. All related mortgage registrations have now been cleared, indicating that the actor has fully repaid the loans.
What’s next for Seo Kang-joon?
Seo recently wrapped up MBC’s action-comedy drama “Undercover High School” earlier this year.
His next project, the Netflix series “Monthly Boyfriend,” is scheduled to be released in 2026.
Real-estate success + steady acting projects = fans are calling him “smart, handsome, AND financially savvy.”
