Contract cancellations up 22% in unregulated Greater Seoul areas as buyers flee tighter rules

A balloon effect is taking hold in Greater Seoul's housing market as tightening regulations on Seoul and other core metropolitan areas push homebuyers toward nearby unregulated zones. Apartment transactions in those areas surged nearly 65 percent in the first half of this year compared to the same period last year, while contract cancellations — sellers voiding deals in anticipation of further price gains — rose 22 percent.

Ham Young-jin, head of Woori Bank's real estate research lab, analyzed Ministry of Land, Infrastructure and Transport actual transaction price data and found that apartment sales in six major unregulated areas of Greater Seoul — Guri, Namyangju, Suwon's Gwonseon-gu, Anyang's Manan-gu, Yongin's Giheung-gu and Hwaseong's Dongtan-gu — totaled 20,688 transactions in the first half of this year, a 64.8 percent jump from 12,556 in the same period last year.

The areas share strong access to Seoul and carry significant development catalysts, including expanded GTX (Metropolitan Express Railway) lines and the formation of a semiconductor industry belt. Their relatively low regulatory threshold has drawn both end-user and investment demand. Gap investment — buying a home while assuming an existing jeonse (long-term deposit lease) — has also gained momentum, adding further upward pressure on buying activity.

Prices have strengthened alongside the demand surge. The average actual transaction price per apartment unit in Guri reached 721.26 million won ($469,000) this year, up 9.3 percent from 659.62 million won last year. Hwaseong's Dongtan-gu also posted a 9.3 percent gain, with the average rising to 812.76 million won from 743.78 million won the previous year. Yongin's Giheung-gu followed with a 7.2 percent increase, then Namyangju at 4.6 percent, Anyang's Manan-gu at 4.1 percent and Suwon's Gwonseon-gu at 3.5 percent.

Local catalysts are driving distinct market dynamics in each area. Guri has rapidly emerged as a leading residential alternative to Seoul's northeastern districts, buoyed by the planned GTX-B line and Han River waterfront development prospects. Yongin's Giheung-gu and Hwaseong's Dongtan-gu have become central pillars of the Greater Seoul housing market by absorbing demand from workers in the semiconductor industry, including employees of Samsung Electronics and SK Hynix. Korea Real Estate Board data as of June 15 show cumulative housing price gains this year reached 9.57 percent in Dongtan-gu and 5.99 percent in Giheung-gu — the highest levels in Gyeonggi Province.

Expectations of further price increases have driven a rise in mid-contract cancellations. The six areas recorded 1,248 apartment sale contract cancellations in the first half of this year, up 21.5 percent from 1,027 in the same period last year. The increase reflects sellers willing to pay penalty fees — double the deposit — to void signed contracts and relist at higher prices.

"Areas such as Guri, Hwaseong's Dongtan-gu and Yongin's Giheung-gu are already approaching the threshold for designation as regulated zones on some quantitative indicators," Ham said. "If market instability centered on these areas persists, the government is likely to consider designating them as regulated zones to curb overheating."
