Dongtan Station Lotte Castle in Hwaseong, Gyeonggi Province — the complex that drew 2.94 million applicants for a single unranked subscription two years ago — is back in the spotlight after setting a new record high of 2.23 billion won ($1.62 million). The 84-square-meter unit, which sold for around 400 million won at its 2017 pre-sale launch, has risen 4.6 times in value over roughly eight and a half years.
According to the Ministry of Land, Infrastructure and Transport's real transaction price disclosure system, an 84.70-square-meter unit on the 33rd floor of Dongtan Station Lotte Castle in Yeoul-dong, Dongtan-gu, Hwaseong, changed hands for 2.23 billion won on June 4. It was the highest price ever recorded for that unit type.
The complex launched in 2017 under the name Dongtan Station Lotte Castle Trinity. A price ceiling on new apartments applied at the time, setting the average pre-sale price at 13.5 million won per 3.3 square meters. Units with an exclusive use area of 84 square meters were offered at between 438 million and 482 million won.
Compared with the highest pre-sale price of 482 million won, the new record is 1.74 billion won more — meaning the price has jumped 4.6 times in about eight and a half years.
From a 1 billion won 'lottery' to 2.2 billion won
Dongtan Station Lotte Castle was at the center of a nationwide "lottery subscription" frenzy in 2024.
A single 84-square-meter unit became available through an unranked subscription after its original contract was canceled, offered at the initial pre-sale price of 482 million won. At the time, the market price for the same unit type was around 1.4 billion to 1.5 billion won, fueling expectations that a successful applicant could pocket a windfall of around 1 billion won.
With eligibility open to applicants nationwide, about 2.94 million people applied. The surge in traffic delayed access to the Korea Real Estate Board's subscription platform, and the application period was extended by one day.
Prices have risen consistently since then. The record high for the 84-square-meter type stood at 1.4 billion won in 2022, 1.62 billion won in 2023 and 1.66 billion won in 2024, before climbing to 1.75 billion won last year. This year the price broke through the 2 billion won mark before soaring to 2.23 billion won in June.
Smaller units have also seen sharp gains. A 65.97-square-meter unit on the 22nd floor sold for 2 billion won on June 6. That was 353 million won more than the 1.65 billion won fetched by the same unit type on April 11, just two months earlier.
GTX-A opening and semiconductor hopes lift Dongtan values
Improved transport links are most often cited as the primary driver of the price surge.
Dongtan Station Lotte Castle is a mixed-use residential and commercial complex directly connected to Dongtan Station. Residents have access to SRT high-speed rail, and the March 2024 opening of the GTX-A line between Suseo and Dongtan cut travel time between the two stations to around 20 minutes.
The complex is also adjacent to Lotte Department Store's Dongtan branch, a shopping mall and a movie theater. The concentration of transport links and commercial amenities around Dongtan Station is widely cited as a key factor behind the area's strong appeal.
Expectations tied to the expansion of the semiconductor industry have also fed into prices. A national industrial complex for advanced system semiconductors is being developed in the Idong and Namsa-eup areas of nearby Yongin. Samsung Electronics is set to build system semiconductor production facilities there, along with materials, components and equipment companies, raising expectations of future job growth and increased residential demand in the surrounding area.
Analysts note, however, that it is too early to say the industrial complex has meaningfully boosted actual housing demand. Much of the recent price appreciation is seen as reflecting both the already-improved transport infrastructure — including the GTX-A line — and anticipation of future development.
A 2.2 billion won home, a 400 million won mortgage cap — tighter rules add uncertainty
As prices have climbed sharply, the financial burden on buyers has grown accordingly.
Under current rules in the Greater Seoul area and regulated zones, the mortgage lending cap for home purchases is 600 million won for properties valued at up to 1.5 billion won, 400 million won for those between 1.5 billion and 2.5 billion won, and 200 million won for those above 2.5 billion won. The actual amount a borrower can access is further constrained by the loan-to-value ratio and debt service ratio regulations.
The record transaction of 2.23 billion won for the 84-square-meter unit falls within the 400 million won lending cap bracket. Even assuming no other debts and a full 400 million won loan, a buyer would still need to cover 1.82 billion won out of pocket.
Regulations have tightened further since the record sale. As home prices continued to surge, the government designated Dongtan-gu in Hwaseong as a speculative overheating zone and an adjustment target area from July 1. Gyeonggi Province then added Dongtan-gu to its land transaction permit zone from July 5.
The loan-to-value ratio for households without a home and for single-homeowners selling their existing property was also tightened to 40 percent, raising the financial bar for any follow-on transactions at similar price levels.
Contract cancellations were also reported in the Dongtan area during May and June, when prices were rising rapidly. A 39th-floor unit of the same 84-square-meter type at Dongtan Station Lotte Castle sold for 2.08 billion won on May 7, but the contract was subsequently canceled.
The June 4 transaction at 2.23 billion won, however, remains on the books as the current record high. With Dongtan's standard 84-square-meter unit now carrying a 2.2 billion won price tag, whether similarly priced deals will continue to emerge amid tightened mortgage and real estate regulations is seen as the key variable shaping the area's price trajectory.
