Dongtan apartment prices surge nearly 2%, tripling prior week's gain

Apartment prices in Dongtan-gu, Hwaseong, Gyeonggi Province rose nearly 2% this week alone, tripling the previous week's gain and marking the steepest increase in the area since the second week of February — roughly four months ago. Dongtan now leads the country in weekly price growth, driven by optimism over a semiconductor industry boom and the opening of the Greater Seoul Express Railway (GTX)-A line, which together have concentrated both investment and owner-occupier demand in the area.

According to the Korea Real Estate Board's weekly apartment price survey for the second week of June 2026 (based on June 8 figures), <style ref="s0">Dongtan-gu apartment prices rose 1.98% from the previous week</style> — more than triple the prior week's gain of 0.6%.

Actual transaction prices reflected the surge. A 97-square-meter unit at Dongtan Station Prugio Central City sold for 2.05 billion won ($1.35 million) on June 6, setting a new all-time high for the complex. A 96-square-meter unit at Dongtan Station Yurim Norway Forest also set a record, changing hands at 1.78 billion won.

The gains extended beyond Dongtan. In Seongnam, Bundang-gu rose 0.62%, led by Gumi and Jeongja-dong where redevelopment expectations are running high, while Jungwon-gu climbed 0.48%, driven by Geumgwang and Sangdaewon-dong. As a result, Gyeonggi Province's overall weekly gain widened sharply from 0.12% to 0.2%. Gwacheon was the exception, falling 0.3% as lower-priced transactions dominated large complexes in Jungang and Byeoryang-dong.

"Residential areas in southern Gyeonggi Province are showing strong price momentum on expectations of a semiconductor industry boom," said Nam Hyeok-woo, a real estate researcher at Woori Bank. <style ref="s0">"In Dongtan's case, buyers are also joining in who want to purchase properties with tenants in place now, ahead of anticipated future price increases."</style>

Seoul also extended its upward trend, with apartment prices rising 0.27% this week, up from 0.25% the previous week. Gangseo-gu posted the steepest gain at 0.42%, led by major complexes in Gayang and Hwagok-dong, while Guro-gu rose 0.4%, driven by Gaebong and Gocheok-dong. Dongdaemun-gu climbed 0.39%, concentrated in small- and mid-sized units in Dapsimni and Hwigyeong-dong, as did Dobong-gu at 0.39%, led by Dobong and Chang-dong. Seongbuk-gu rose 0.35%, with gains centered on major complexes in Donam and Jongam-dong, while Gangbuk-gu advanced 0.34%, driven by Mia and Beon-dong.

Among the three high-end Gangnam districts, Gangnam-gu and Songpa-gu each widened their gains from the prior week, rising 0.25% and 0.33% respectively, while Seocho-gu edged up 0.2%, a slight narrowing from the previous week's 0.21%.

"While some areas are taking a wait-and-see approach, demand has been steadily building around major reconstruction and redevelopment projects and large complexes, with upward transactions continuing to be recorded across Seoul," a Korea Real Estate Board official said.

Meanwhile, Seoul's weekly jeonse prices also accelerated, rising 0.32% compared with 0.29% the previous week. Seongdong-gu led with a 0.64% gain, driven by major complexes in Haengdang and Oksu-dong. Dobong-gu rose 0.55%, concentrated in large complexes in Chang and Dobong-dong, while Songpa-gu climbed 0.53%, led by large complexes in Jamsil and Sincheon-dong.

In Gyeonggi Province, Hwaseong's Dongtan-gu also topped the jeonse rankings with a 0.52% gain, led by complexes with strong residential amenities in Mok and Neung-dong. Gwangmyeong rose 0.44%, driven by transit-oriented areas in Haan and Cheolsan-dong.

"Amid persistently high jeonse demand, tenant inquiries have increased and waiting demand has accumulated around major complexes — particularly transit-oriented areas and large complexes with strong residential conditions — resulting in upward contract signings across Seoul," a Korea Real Estate Board official said.
