Seoul's H2 2026 presale market is maintaining a taut tension between "supply ambition" and "demand contraction." Even as the Seoul Metropolitan Government announced a target of 310,000 units by 2031, Yonhap News reports that following the capital gains tax (yangdo-se jungkwa) surcharge in May, Seoul apartment transactions in June fell sharply from the previous month and wait-and-see sentiment became pronounced. This lag—where supply schedules are being pushed forward while buying sentiment retreats—is the key variable for the second-half cheongyak (housing subscription) market.
Seoul's Supply Plan: The Weight of the Numbers
According to the Korea Economic Daily, the Seoul Metropolitan Government announced it will "supply 310,000 housing units by 2031 and deliver results citizens can feel." Simply annualized, that comes to roughly 50,000–60,000 units per year. Given that Seoul's annual authorization and groundbreaking volumes have typically hovered around 30,000–40,000 units, this target is exceptionally high — a fact worth acknowledging upfront.
What matters is the lag between "plan" and "actual presale." The authorization → groundbreaking → presale → move-in pipeline for redevelopment and reconstruction projects takes years. Whether all 310,000 units Seoul announced will actually be move-in ready before 2031, or whether that figure is measured at project approval stage, is something end-buyers must verify. A large headline number does not mean presale supply will be abundant next year or the year after.
For the supply plan to materialize, the speed of authorization for redevelopment and reconstruction projects is the linchpin. Seoul emphasized "results citizens will feel" — which in other words acknowledges that tangible results have not yet reached that level. When scanning the presale calendar, a discerning eye is needed to determine at which "stage" of this supply plan a given volume falls.
Yongsan: Where Redevelopment Is Gaining Speed
The Korea Economic Daily reported that redevelopment and reconstruction around Yongsan Station and along the Han River are gaining momentum. Yongsan is a zone where three development narratives overlap — GTX-B Line, the Yongsan International Business District, and Han River views — making it one of the areas within Seoul with the strongest project momentum.
However, "gaining speed" does not mean a presale schedule has been confirmed. Redevelopment and reconstruction projects must proceed through the stages of association establishment → project implementation approval → management and disposition plan approval → relocation and demolition → groundbreaking → presale. At each stage, variables such as lawsuits, inter-member disputes, and cultural heritage surveys can push the presale date out by six months to several years. Given the high expectations for Yongsan's Han River riverfront, verifying which authorization stage a project is currently at must come first.
It is reasonable to pay attention to Yongsan when reviewing H2 presale candidates, but "redevelopment and reconstruction momentum" is a news-reporting benchmark — "presale calendar confirmation" is a separate administrative procedure. Checking whether a complex's invitation for residents has been registered on Cheongyak-home (applyhome.co.kr) is the most accurate method.
Transaction Decline and Wait-and-See: Impact on the Cheongyak Market
The wait-and-see mood in the resale market is directly linked to cheongyak demand. According to Yonhap News, following the capital gains surcharge that took effect on May 10, Seoul apartment transactions in June dropped sharply from the previous month. The surcharge constrains multi-home owners' selling and simultaneously suppresses move-up demand. End-buyers who plan to sell their existing home and then chase a cheongyak must first calculate how the tax environment interacts with their strategy.
Two scenarios coexist for complexes going on presale in a heightened wait-and-see environment. One is that lower competition rates widen the window for winning a ballot; the other is that short-term premium formation stalls, investment-motivated demand retreats, and only genuine end-buyers remain. Neither scenario is necessarily unfavorable for end-buyers, but the spread between the presale price and surrounding market prices (discount rate of presale price relative to prevailing market) deserves close scrutiny.
Beyond that, Yonhap News reported that prosecutors have designated dedicated prosecutors for real estate speculation nationwide and announced a strict crackdown on price manipulation — in line with the Lee Jae-myung administration's "all-out" real estate price stabilization stance. This regulatory and enforcement climate is likely to further suppress cheongyak demand driven by short-term profit motives. Paradoxically, for applicants seeking actual occupancy, the competitive environment may improve somewhat.
The bigger the supply plan number, the better it sounds — but the one question that is valid for an end-buyer is: "Which stage is the specific complex I can apply for right now?"
Presale Price, Tax, and Project Stage: H2 Cheongyak Checklist
For end-buyers evaluating H2 cheongyak applications, using the items below as a framework to assess each complex is effective. There is always a gap between the optimism in media coverage and the reality of administrative procedures. Verifying numbers and stages directly is the way to find opportunities even amid a wait-and-see market.
| Verification Item | Verification Method | Key Issue |
|---|---|---|
| Resident invitation registration status | Cheongyak-home (applyhome.co.kr) | Confirm gap between reported and actual schedule |
| Whether presale price cap applies | Ministry of Land announcement, public notice | Understand basis for presale price calculation |
| Redevelopment/reconstruction authorization stage | Seoul City's Jeongbi Mongttang (정비사업 정보몽땅) | Confirm whether past management and disposition approval stage |
| Cheongyak eligibility (special/general supply) | Read the public notice directly | Household head status, years without home, point items |
| Capital gains surcharge applicability | National Tax Service Hometax tax calculator | Tax impact when selling existing home |
| Gap between surrounding market and presale price | Ministry of Land real transaction price disclosure system | Compare presale price to prevailing market level |
Things to Verify
- Confirm on Cheongyak-home that the resident invitation (ipjuja mochip gonggo) for the complex of interest has actually been registered — "expected presale" in a press article and an official notice are different things.
- Check on Seoul's Jeongbi Mongttang site whether the redevelopment/reconstruction project has completed its management and disposition plan approval — if it is at an earlier stage, H2 presale is unlikely.
- Simulate on the National Tax Service Hometax calculator how your current home ownership will be affected by the capital gains surcharge (effective May 10) if you sell.
- Directly compare the presale price in development-expectation areas like Yongsan against nearby prices in the Ministry of Land's real transaction price disclosure system — to verify whether the premium has already been baked into the presale price.
- Confirm from official press releases which specific districts and project sites within Seoul's 310,000-unit supply plan are at a stage where presale is feasible within the target period.
- Verify physical defects such as mechanical room noise and sunlight obstruction before signing — courts have actually ruled that a sale contract concealing noise was justifiably cancelled (Yonhap News).
