Seoul's top apartments are losing value while large newer complexes hold steady, and the split is widening under tighter government rules.
Market capitalization across the KB Leading Apartment 50 index fell 2.7 trillion won between August and October, with Gangnam redevelopment complexes driving most of the decline. Smaller units are gaining share in Seoul, while Gyeonggi buyers favor mid-sized homes. For buyers and owners, location, building age, and loan limits now matter more than ever.
