BTS members RM and Jimin made headlines in 2021 after acquiring luxury apartments at Nine One Hannam, one of Seoul's most prestigious residential developments. RM paid 6.36 billion South Korean won, while Jimin completed a rental-to-ownership conversion valued at 5.9 billion won. Their combined investment amounted to 12.26 billion won, equivalent to approximately $11 million at the exchange rates reported at the time. Both transactions were reportedly completed without mortgage loans. The purchases attracted considerable attention as the two artists expanded their personal real estate holdings in South Korea's luxury property market.
How Much Did RM and Jimin Pay for Their Apartments?
According to South Korean media reports published on June 1, 2021, RM and Jimin secured apartments at Nine One Hannam in Seoul's Hannam-dong neighborhood on March 31, 2021.
RM, whose real name is Kim Nam-joon, acquired his apartment for 6.36 billion won, approximately $5.7 million at the time.
Jimin, whose real name is Park Ji-min, completed the ownership conversion of his apartment for 5.9 billion won, approximately $5.3 million.
The two transactions had a combined value of 12.26 billion won, or approximately $11 million.
- RM: ₩6.36 billion (approximately $5.7 million).
- Jimin: ₩5.9 billion (approximately $5.3 million).
- Combined value: ₩12.26 billion (approximately $11 million).
Both apartments had an exclusive floor area of approximately 244.34 square meters, equivalent to 2,630 square feet. Despite their similar dimensions, RM's unit was reportedly more expensive because it included a terrace.
South Korean media reported that both transactions were completed without mortgage financing, meaning the purchases did not rely on conventional property loans.
Inside Nine One Hannam, One of Seoul's Most Expensive Residential Developments
Nine One Hannam is a luxury residential complex located in Hannam-dong, Yongsan District, Seoul. Completed in 2019, the development contains 341 residential units across nine buildings.
The property was developed on land previously occupied by housing for U.S. military personnel and their families. Its location between the Han River and Namsan Mountain makes it particularly attractive to affluent buyers seeking privacy and convenient access to central Seoul.
The complex is known for its extensive residential facilities, which include:
- Indoor swimming pool and fitness facilities.
- Indoor golf practice facilities.
- Private party rooms and guest accommodation.
- Concierge and residential management services.
- Private parking and storage facilities.
- Enhanced access control and residential security.
Its large apartment layouts, exclusive amenities, and emphasis on privacy have made Nine One Hannam popular among celebrities, business executives, and wealthy property investors.
Why Nine One Hannam Attracts Celebrity Buyers
Privacy is one of the most important features of Nine One Hannam, particularly for celebrities who want to maintain a separation between their professional and personal lives.
The development incorporates controlled access, private residential facilities, and security arrangements designed to reduce unwanted attention from visitors and the public.
Its location in Hannam-dong also provides convenient access to major business districts, entertainment facilities, restaurants, and cultural destinations.
For wealthy buyers, the combination of location, limited residential inventory, and exclusive amenities makes the complex an attractive long-term property investment.
Nine One Hannam Apartment Prices Have Increased Dramatically
Property transactions involving apartments of approximately 244 square meters at Nine One Hannam demonstrate substantial price appreciation since RM and Jimin acquired their units in 2021.
Reported transactions for comparable apartments include:
- April 2024: ₩120 billion.
- August 2025: ₩167 billion.
- January 2026: ₩140.4 billion.
- March 2026: ₩156.5 billion.
The August 2025 transaction established a particularly high recorded price for an apartment in this size category, illustrating the strength of demand for luxury residential properties in the development.
However, these figures represent transactions involving other units in the complex. They should not be interpreted as confirmed market valuations of RM's or Jimin's individual apartments.
Differences in floor level, terrace availability, orientation, condition, and individual property characteristics can significantly affect the final selling price.
RM's Earlier Real Estate Investment in Hannam The Hill
RM also had a significant property investment in another prestigious Seoul residential development, Hannam The Hill.
He reportedly purchased an apartment measuring approximately 232 square meters in November 2019 for 4.9 billion won.
On March 5, 2021, he sold the property for approximately 5.8 billion won, generating a reported price difference of 900 million won before transaction costs and taxes.
The sale took place shortly before his acquisition of the larger apartment at Nine One Hannam, highlighting his continued interest in Seoul's premium residential property market.
Conclusion
RM and Jimin's acquisitions at Nine One Hannam represented a combined property investment of approximately 12.26 billion won, equivalent to around $11 million in 2021. RM acquired his apartment for 6.36 billion won, while Jimin completed an ownership conversion valued at 5.9 billion won.
Both properties are located in one of Seoul's most exclusive residential developments, which has recorded substantial increases in comparable apartment transaction prices in subsequent years.
Although the original purchases demonstrate the financial success of the two BTS members, their apartments' current individual market values have not been publicly established. The reported $57 million figure should therefore not be presented as the amount they originally spent or as a verified valuation of their combined holdings.
