The First Reversal in 2 Years: 5 Signals Gangnam's Shift to a 'Buyer's Market' Is Sending Through Seoul's Real Estate Landscape
The apartment supply-demand index for the Gangnam 3 districts fell for 5 consecutive weeks, reaching 100.0 (equilibrium) for the first time in 2 years, while Seoul apartment listings surged 26% in a single month. As multi-home owners flood the market with distress sales, buyers are holding back in a FOBO (Fear of Better Option) mindset.

Why does this matter now? The Gangnam apartment market — long called "unbeatable" since 2024 — has reached an equilibrium point for the first time. As President Lee's crackdown on multi-home owners becomes a reality, Gangnam's holdout property investors are finally joining the selling side.
TL;DR
- The apartment supply-demand index for the Gangnam 3 districts (Gangnam, Seocho, Songpa, Gangdong) hit 100.0 in the 4th week of February (as of the 23rd), falling for 5 consecutive weeks from 104.13 in the 3rd week of January
- Seoul's buyer-dominance index dropped to 73.4 (as of February 23), plunging sharply in just 3 weeks from 99.3 at the end of January
- Seoul apartment listings jumped 26% in a single month, with the Gangnam 3 districts and Yongsan-gu turning negative for the first time in 2 years
- Buyers are sitting on the sidelines due to FOBO (Fear of Better Option) psychology
- President Lee's real estate comments and anti-multi-home-owner stance are driving sentiment
1. The Facts: What Is Happening
According to the weekly apartment price trend report (4th week of February, as of February 23) released by the Korea Real Estate Board, Seoul apartment transaction prices rose 0.11% week-on-week, but the Gangnam 3 districts and Yongsan-gu turned negative for the first time in approximately 2 years.
A 84㎡ unit at DIH Firstier i-Park in Gaepodong, Gangnam-gu traded for KRW 3.935 billion on February 14, but a recent distress listing at KRW 3.5 billion appeared — a drop of over KRW 400 million in a single month. A 84㎡ unit at Raemian One Bailey in Banpo, Seocho-gu also came down from KRW 6.08 billion in January to an asking price of KRW 5.52 billion. Both properties are reported to be distress sales by multi-home owners.
KB Real Estate's Seoul buyer-dominance index stands at 73.4. A reading below 100 means the market is in "buyer-dominant" territory — the lower it goes, the more sellers outnumber buyers.
2. Drivers: Why the Sudden Shift Now
Policy Direction Reversal
President Lee has continued to make statements regarding the disposal of multi-property holdings by politicians, declaring an intent to "rigorously design taxes and regulations." Cheong Wa Dae described this as "a strong commitment to normalizing the real estate market." The symbolic ripple effect grew when the President's own apartment was listed for sale.
Psychological Turning Point for Multi-Home Owners
Gangnam multi-home owners who had held on since 2024 have begun offloading properties — especially units with existing lease tenants — as distress sales. The move reflects growing concern that property holding taxes and capital gains tax burdens will soon become unavoidable.
The FOBO Reversal
In the past, buyers were driven by FOMO (Fear of Missing Out — "if I don't buy now, I never will"). Today, FOBO (Fear of Better Option) is dominant. Park Won-gap, Senior Expert Advisor at KB Kookmin Bank, notes that the perception of "buying now means overpaying" has become widespread.
3. Context: Historical Significance
The Gangnam 3 districts' supply-demand index reaching 100.0 is the first time in 2 years. This figure represents the equilibrium point at which sellers and buyers are equal in number. Once it falls below this level, the market officially transitions to buyer dominance.
| Period | Gangnam 3 Districts Supply-Demand Index | Seoul Buyer-Dominance Index |
|---|---|---|
| 3rd Week of January 2026 | 104.13 (peak) | 99.3 |
| 4th Week of February 2026 | 100.0 (equilibrium) | 73.4 |
| Change | ▼ 4.13 points | ▼ 25.9 points |
Previously, Seoul apartment prices had risen for 54 consecutive weeks since 2024. That upward trend is now showing its first crack at the heart of Gangnam.
4. Outlook: How Long Will This Last?
Short-term (1–3 months): A wait-and-see mood will persist until multi-home owner distress inventory is absorbed. The Gangnam 3 district decline is likely to spread to the Han River belt areas of Mapo and Seongdong.
Medium-term (3–6 months): The direction will depend on the level of legislative action targeting multi-home owners. If the March extraordinary session of the National Assembly takes up additional real estate bills, downward pressure will intensify.
Risk Factors:
- Rebound potential: Structural undersupply in key Seoul areas remains. A re-rally after distress inventory is cleared is possible
- Overcorrection risk: A concentration of multi-home seller activity could distort prices
- Interest rate variable: Any further Bank of Korea base rate cut could reignite buyer sentiment
