Seoul’s apartment market is showing broad-based price pressure, with average non-Gangnam presale prices reaching a record 60.62 million won per 3.3 square meters from January through August, up 51% year on year, while demand for 84-square-meter units has produced 386 same-complex price inversions through July. Higher existing-home prices, strong end-user demand, restricted rental supply and policy uncertainty are driving the market, alongside 6,680 suspected gap-investment transactions from November 2024 through October 2025.
