Growth in apartment prices in Seoul slowed this week from a week earlier, while prices in key districts fell, apparently on recent government warnings of regulatory measures against owners of multiple homes, data showed Thursday. According to the data compiled by the Korea Real Estate Board, the average price of an apartment unit in Seoul rose 0.11 percent as of Monday from a week earlier. The reading is 0.04 percentage point lower than that of the previous week, marking the fourth consecutive week of slowing growth. In particular, major upscale districts — Gangnam, Songpa, Seocho and Yongsan — where high-end apartment complexes are concentrated posted weekly declines of 0.06 percent, 0.03 percent, 0.02 percent and 0.01 percent, respectively. Prices in Gangnam, Seocho and Yongsan recorded their first on-week declines in about two years, while those in Songpa fell for the first time since the fourth week of March 2025. Market observers said the slowdown came as some owners of multiple homes rushed to sell properties at lower prices ahead of the planned expiration of heavy capital gains
