In June 2026, Seoul apartment prices rose across all 25 districts at once for the first time in four months. This was not a rally in a few pockets but a citywide climb. More than a year after tough lending curbs took effect, a pattern in which the jeonse crunch pushes up sale prices has hardened, and the government—concluding that suppressing demand alone is not enough—has signaled a supply-expansion package for late July. 📊

TL;DR

  • June’s Seoul apartment sale-price index hit 105.8 (January 2026 = 100), up 5.8% from the start of the year, with all 25 districts rising together for the first time in four months.
  • The average jeonse price across Gangnam’s 11 districts reached 801.93 million won, topping 800 million won for the first time ever.
  • The government has signaled a “comprehensive real estate package” for late July, combining supply expansion and tax reform.

📈 Why Is “All 25 Districts Rising” in June an Important Signal?

The standout in June’s data is that even Gangnam, which had been falling, rebounded. High-end and mid-to-low-priced areas alike climbed across the whole city. According to KB Real Estate’s monthly figures (as of June 15), Seoul’s apartment sale-price index stood at 105.8 (January 2026 = 100)—up 1.1% from 104.7 the previous month and 5.8% from the start of the year. All 25 districts turned to gains for the first time in four months, and it is especially symbolic that Gangnam, down for three straight months, rebounded.

Seoul apartment prices have now risen for more than 70 straight weeks (some tallies put it at 71–72). A rally that had been concentrated in certain areas and smaller units spread citywide in June.

🔑 The Jeonse Crunch Pushes Up Sales — Gangnam Jeonse Tops 800M Won

As jeonse prices climb steeply, tenants who had been hunting for leases are turning to buying instead. In June, Seoul apartment jeonse prices rose 1.43% from a month earlier—the largest gain this year—and the average jeonse price reached 696.19 million won, up 4.0% from January (669.48 million won). Above all, the average jeonse price across Gangnam’s 11 districts hit 801.93 million won, topping 800 million won for the first time on record.

Just how tight the jeonse supply is shows up in the supply-demand index. Seoul’s apartment jeonse supply-demand index rose to 122.5, the highest in five and a half years—meaning demand for leases far outstrips available listings.

🏙️ Where Prices Are Rising — Nodogang, Geumgwangu, and Buyers in Their 30s

Buyers with limited funds are flocking to mid-to-low-priced and outlying complexes, driving a so-called “catch-up” effect. With heavy loan curbs and the jeonse crunch overlapping, record-high prices keep appearing in lower-barrier, mid-priced clusters such as Nodogang (Nowon, Dobong, Gangbuk) and Geumgwangu (Geumcheon, Gwanak, Guro). In Gangbuk-gu, the average apartment sale price has topped 700 million won.

First-time buyers in their 30s stand out in particular. In Nowon-gu, buyers in their 30s rose from 258 in February to 368 in March, a 43% jump; over the same period Dobong-gu surged 55% and Gangbuk-gu 229%. As listings piled up ahead of the reinstatement of the heavier capital-gains tax on multiple-home owners, young buyers appear to have seized the moment as a chance to buy their first home, flocking to mid-priced areas.

🏛️ Is the Government’s Next Card “Supply”? — A Comprehensive Package Signaled for Late July

Concluding that suppressing demand alone has its limits, the government is now shifting its weight toward expanding supply. Marking his first year in office, President Lee Jae-myung said “the tax issue should be possible around July” and pledged to “speed up and soon announce a supply package as well.” A “comprehensive real estate package” combining supply expansion and tax reform is expected in late July, and the presidential office has also signaled an intensive debate on housing.

The outline is already in place. On January 29, the government’s “Plan to Expand and Accelerate Urban Housing Supply” pledged 60,000 units in prime Seoul-metropolitan locations by 2030. The Yongsan International Business District would rise from an original 6,000 units to up to 10,000 through higher floor-area ratios; the former Gwacheon racecourse site would provide 9,800 units; and the Taereung golf course (CC) site 6,800 units. Still, with relocation roadmaps and negotiations with local governments unresolved, a time lag before actual groundbreaking and move-in is unavoidable.

Overall Take 📝

June’s Seoul property market boils down to two phrases: “broad-based rally” and “jeonse crunch.” More than a year of loan curbs notwithstanding, gains spread citywide from Gangnam to the outskirts, and demand worn down by the jeonse crunch shifted into mid-priced purchases, with buyers in their 30s conspicuous. Gangnam jeonse topping 800 million won for the first time captures this trend best.

The key question now is the direction—and effectiveness—of the comprehensive package the government will unveil in late July. How it adjusts taxes (long-term holding deductions, holding taxes) and how far the volume and speed of supply calm market anxiety will shape the second half. But because supply measures carry a large gap between announcement and actual move-in, it is worth watching not just what is announced but how quickly it is carried out.
