In the past year, the area with the largest increase in apartment prices nationwide was Bundang District in Seongnam, Gyeonggi. In Seoul, Dongjak, Gwangjin and Seongbuk districts recorded higher growth rates than Gangnam and Seocho districts, showing that the rise in home prices is spreading to non-Gangnam areas and key regions in Gyeonggi.
On the 7th, ZIGBANG CO. Big Data Lab analyzed nationwide apartment sales prices from September 2025 to August this year and found that Seongnam's Bundang District rose 29.5% over the year, the highest growth rate among all cities, counties and districts.
Following Bundang, Gwangmyeong in Gyeonggi ranked second at 28.4%. Seoul's Dongjak District rose 25.3%, Suji District in Yongin, Gyeonggi rose 24.8%, and Seoul's Gwangjin District rose 23.8%.
Hanam in Gyeonggi (22.8%), Seongdong District in Seoul (22.6%), Seongbuk District (22.4%), Dongtan District in Hwaseong, Gyeonggi (21.4%), and Songpa District in Seoul (17.7%) also made the top 10. All of the top 10 regions by growth rate clustered in the greater Seoul area.
In Bundang, prices jumped mainly in Yatap, Seohyeon and Gumi-dong as expectations for redevelopment and remodeling continued. Gwangmyeong likewise saw a pronounced rise centered on complexes pursuing redevelopment in Cheolsan-dong.
In particular, the composition of the top-tier regions by growth rate changed significantly over the past year.
In the previous year, Gangnam District rose 22.6% and Seocho District 19.3%, with Seoul's Gangnam area leading the market. But in the past year, the growth rates fell to 6.8% for Gangnam and 8.0% for Seocho.
By contrast, Dongjak District's increase widened from 12.7% in the previous year to 25.3% recently. Gwangjin District rose from 12.0% to 23.8%, and Seongdong District climbed from 15.6% to 22.6%.
Seongbuk District's shift was also notable. Its growth rate was only 4.6% in the previous year but jumped to 22.4% in the past year.
In Gyeonggi, Gwangmyeong's increase expanded sharply from 3.8% in the previous year to 28.4% recently. Suji in Yongin, Hanam and Dongtan in Hwaseong also rose only 0.8% to 6.4% in the previous year but have all climbed more than 20% recently.
As of the end of August, apartment prices per 3.3㎡ were 37.1 million won in Hanam and 35.56 million won in Gwangmyeong. Suji in Yongin was 28.98 million won, and Dongtan in Hwaseong was about 27.04 million won.
Many regions also saw an increase in transactions along with rising prices.
In Dongtan District in Hwaseong, which newly entered the top tier by growth rate over the past year, the number of actual transactions rose 115.0% from the previous year. Seongbuk District increased 33.0%, Gwangmyeong 24.4%, Hanam 18.1%, and Suji District in Yongin 13.6%.
Conversely, Gwacheon, which had been strong in the earlier upcycle, saw transaction volume fall 55.9%. Gangnam and Seocho districts also declined 28.6% and 26.9%, respectively.
ZIGBANG CO. analyzed that, as lending and tax regulations have concentrated relatively on high-priced homes, demand may have shifted to areas with lower price burdens.
A ZIGBANG CO. official said, "With the expansion of regulated areas under the Oct. 15 measures last year, the loan limit for dwellings over 1.5 billion won was reduced, and the August tax reform plan also proposed strengthening property taxes on ultra-high-priced dwellings," adding, "As loan and tax burdens focus on high-priced dwellings, some demand may have shifted to areas with relatively lower price burdens."
