Korea's Apartment Market Splits: Seoul Records, Suwon Discounts

A month of registered apartment sales filed with Korea’s Ministry of Land, Infrastructure and Transport shows a housing market pulling apart at the seams: a Yeongdeungpo District unit set an all-time high for its floor plan at 1.4 billion won on 5 July 2026, while units in 1980s-era Suwon complexes changed hands the same fortnight for less than a fifth of that. Within individual complexes, meanwhile, identical floor plans traded in opposite directions within days — the mark of a market with few transactions and weak price discovery.

The Daerim-dong ceiling

The record belongs to Daerim Hyundai 3rd Complex in Daerim-dong, Yeongdeungpo District, where a 140-square-meter unit (net floor area) on the 26th floor sold for 1.4 billion won. That surpasses the previous best for the same floor plan, 1.3 billion won recorded on 9 March 2021 — a gain of 100 million won, or roughly 7.7 percent, spread across more than five years. Annualized, that is a low-single-digit pace: a nominal record that, against Korean inflation over the same stretch, is closer to flat in real terms. The complex dates to October 1997 and holds 1,162 units across seven buildings.

Yeongdeungpo’s narrow band

The district’s mid-size stock now clusters tightly. Boramae Kyungnam Honorsville in Singil-dong logged an 84-square-meter unit at 1.375 billion won on 25 June, then a comparable unit one floor tier higher at 1.35 billion won the next day — 25 million won lower despite the better position. Yeongdeungpo Samhwan’s 59-square-meter units printed 1.47 billion won on 26 June and 1.475 billion on 30 June, a five-million-won spread. Yangpyeong Hanshin, also at 59 square meters, went for 1.347 billion won on 28 June and 1.36 billion on 1 July.

The pattern worth noting is not the level but the compression: a 59-square-meter unit in Yangpyeong-dong and an 84-square-meter unit in Singil-dong are being priced within about 30 million won of each other. Buyers in this corridor are paying for the district, not the square meters. Seocho Jinheung in Seocho District sits in a different market entirely — 4.21 billion won for a 160-square-meter unit on 2 July, in a 615-unit complex occupied since August 1979, where the value is redevelopment optionality rather than the building itself.

Suwon: the same address, two directions

Jangan-gu in Suwon offers the sharpest illustration of thin-market volatility. At Suwon Hanil Town — 5,282 units across 58 buildings, occupied since August 1999 — two 59-square-meter sales dated 1 July came in at 498 million and 526 million won, a 28-million-won gap on the same day for the same floor plan. A third, dated 15 July, printed 490 million. An 84-square-meter unit on the first floor fetched 500 million won on 12 July, essentially level with the smaller units on higher floors.

Jeongja Dongshin 1st, built in May 1987, shows the same churn at a lower altitude: 56 square meters at 290 million won on 16 July against 275 million on 13 July, with a 66-square-meter unit at 350 million on 6 July. Suwon SK Skyview’s 84-square-meter units went for 830 million won on 6 July and 890 million on 13 July — a 60-million-won move in a week. And Hwaseo Station Park Prugio, completed in August 2021, cleared 1.54 billion won for 101 square meters on 16 July, above every Yeongdeungpo print in this batch.

That last figure is the real story of the Gyeonggi market. Suwon is not uniformly cheap; it is bifurcated. New construction near a rail node outprices central Seoul’s aging mid-rise stock, while 1980s and 1990s complexes a few kilometers away trade at levels that have barely moved. In Daegu, Castle Gold Park in Suseong District’s Hwanggeum-dong — 4,256 units, occupied July 2006 — registered 538 million won for 74 square meters, roughly in line with Suwon’s older inventory and a reminder that the premium tiers are geographically narrow.

Reading the filing dates

One quirk deserves explanation, because it trips up anyone reading the registry directly. Contracts appear in the public database as they are filed, not in the order they were signed, and Korean law allows a window between agreement and reporting. A sale dated 6 July can therefore surface alongside — or after — one dated 13 July. Any single comparison between two consecutive prints is a comparison of filing sequence as much as of market direction, which is why the day-to-day swings above should be read as dispersion, not trend.

What the spread implies

Taken together, the July filings describe a market where the ceiling is grinding higher very slowly and the floor is not moving at all. Daerim Hyundai’s record required more than five years to add 7.7 percent. Suwon’s older complexes are clearing at prices that would not have looked unusual a decade ago. The gap between a 290-million-won unit in Jeongja-dong and a 1.4-billion-won unit in Daerim-dong is now roughly 4.8 times — for apartments about an hour apart.

For policy, that spread is the constraint. Measures aimed at cooling Seoul prices land on a segment already appreciating below inflation, while the stock where affordability actually binds shows no upward pressure to cool. For buyers, the practical lesson is narrower: with same-complex, same-floor-plan sales diverging by 5 to 7 percent inside a single week, a single registered price is a data point, not a valuation.
