The gap between the most expensive and the least expensive apartment sales prices in Gangnam-gu ranked overwhelmingly first among all districts in Seoul. Although transactions surpassing 20 billion won appeared in top-tier locations such as Cheongdam-dong, there were also deals in the several hundred million won range, highlighting the pronounced polarization.

According to an analysis of the Ministry of Land, Infrastructure and Transport's real transaction price disclosure system as of May 25, 2026, the price gap between the most expensive and the least expensive apartments in Gangnam-gu, from January 1 to May 15 this year, was calculated at 21.62 billion won. On May 15, a 231-square-meter apartment in Eterno Cheongdam, Cheongdam-dong, was sold for 21.8 billion won, marking the highest price. In contrast, a 16-square-meter apartment in Hanyang Sujain Urban Gate, Nonhyeon-dong, was sold for 180 million won.

Following Gangnam-gu, the area with the next largest gap between the highest and lowest apartment prices was Yongsan-gu (15.47 billion won), home to high-end residential complexes such as Nine One Hannam and Hannam The Hill. A 244-square-meter unit in Nine One Hannam, Hannam-dong, set the record for the highest price at 15.65 billion won. Seocho-gu also showed a significant gap of 9.839 billion won. In Banpo-dong, a 191-square-meter unit in Raemian One Pentas was sold for 10 billion won, reflecting a severe polarization of top and bottom prices, second only to Yongsan-gu.

Even within Gangnam-gu, apartment prices fell sharply in outlying areas compared to the premium locations of Cheongdam and Apgujeong-dong. During the same period, the average price of all apartments traded in Gangnam-gu was 2.63624 billion won, the highest in Seoul, but apartments in outlying areas such as Segok-dong, Jagok-dong, and Yulhyeon-dong were sold below this average.

For example, a 118-square-meter apartment in Segok Rienpark Complex 3, located in Segok-dong adjacent to Seongnam-si, Gyeonggi-do, was traded for 1.18 billion won in January, about 1.4 billion won lower than the Gangnam-gu average. In Jagok-dong, which is north of Segok-dong and closer to the city center, prices were higher but still below the average. Last month, a 118-square-meter unit in Raemian Gangnam Hills, Jagok-dong, was sold for 2.3 billion won. Although these units are larger than the standard 84-square-meter type, prices remain below the district average when the location is far from the city center and lacks infrastructure such as nearby subway stations.

Kwon Youngsun, team leader at Shinhan Bank Real Estate Investment Advisory Center, commented, "Areas like Segok-dong and Jagok-dong developed as greenbelt restrictions were lifted, and infrastructure such as transportation is expected to be established in the future." He added, "However, given the strong demand for ultra-high-end residences like Eterno Cheongdam and Nine One Hannam, it will be difficult to curb polarization within these prime locations."
