Apartment prices in the Gyeonggi "Gyeongbu line" area centered on the Gyeongbu Expressway are rising quickly. In Hwaseong Dongtan, Suwon Yeongtong, and Yongin Suji—where the trio of "transportation, jobs, and residential environment" aligns—record-high transaction after transaction is emerging, putting them on the verge of joining the "2 billion won club" for the national standard size (exclusive area 84㎡).
According to the actual transaction price disclosure system of the Ministry of Land, Infrastructure and Transport on the 25th, an 84㎡ exclusive unit at "Dongtan Station Lotte Castle (moved in 2021, 940 households)" in Yeoul-dong, Dongtan-gu, Hwaseong, Gyeonggi Province set a record high with a transaction at 1.9 billion won on the 20th of last month. The asking price of listings currently on the market is 1.95 billion won, nearing 2 billion won. An 84㎡ exclusive unit at "Jayeon & Hillstate (2012, 1,764 households)" in Iui-dong, Yeongtong-gu, Suwon was transacted at 1.89 billion won in January. The same size currently has listings up to 2.2 billion won.
Dongtan is the Seoul metropolitan area's largest industrial hub concentrated with large corporations such as Samsung Electronics and venture firms, and, as a key transportation node served by high-speed rail SRT, KTX, and GTX (Metropolitan Express Railway), it has seen steady inflows of investment demand. The fact that it was exempt from land transaction permit regulations is also analyzed to have influenced the increase in transaction volume. Yeongtong, home to the Gwanggyo New Town, also has many transportation tailwinds. The Dongtan–Indeogwon Line, connecting Dongtan Station and Indeogwon Station, and the Shinbundang Line Gwanggyo–Homaesil extension, connecting Suwon east–west, are scheduled to open in 2029. A plan to extend the Yongin light rail to Gwanggyo is also under discussion.
Apartment prices in Yongin Suji are also rising quickly in step. An 85㎡ exclusive unit at "Seongbok Station Lotte Castle Gold Town (2019, 2,356 households)" in Seongbok-dong, Suji-gu, Yongin changed hands for 1.71 billion won on the 23rd of last month. The highest asking price for the same size is 2 billion won. According to the Korea Real Estate Board (REB), in the third week of this month (as of the 16th), the place where the apartment sale price index rose the most compared with the end of December last year was Suji in Yongin, Gyeonggi, with a 5.8% increase. Bundang in Seongnam, Gyeonggi ranked third at 3.60%, while Yeongtong in Suwon and Dongtan in Hwaseong recorded increases of 2.44% and 1.31%, respectively.
In Bundang, Seongnam, a representative area of the Gyeongbu line, the national standard size has surpassed 2.5 billion won. An 84㎡ exclusive unit at "Baekhyeon Village Complex 6 (2009, 396 households)" in Baekhyeon-dong, Bundang-gu, Seongnam set a record high with a transaction at 2.695 billion won on the 4th of last month, and an 84㎡ exclusive unit at "Parkview (2004, 1,829 households)" in Jeongja-dong recorded a transaction at 2.63 billion won in January.
The steep rise in home prices along the Gyeongbu line is because there is not much housing supply relative to demand. According to Real Estate R114, over three years (2026–2028), the only new move-in supply in Bundang, Seongnam and Suji, Yongin is 873 households at "The Sharp Bundang Tier One," scheduled to move in in 2027. An official at a major construction company said, "With the creation of the Yongin semiconductor cluster and transportation tailwinds, the pool of would-be entrants is growing, but supply is flat, so home prices are rising," adding, "In Bundang and Suji, where there is a shortage of land to build new apartments, expanding new supply by increasing redevelopment projects could be an alternative."
