Korea Apartments, Loans and Jeonse — 2026-09-11

Seoul’s apartment price surge has entered its 83rd consecutive week, driven by demand for homes under 1.5 billion won, even as Gangnam and Seocho districts see their first significant declines in months due to tax reforms and listing surges. Meanwhile, the jeonse market shows signs of strain, with officetel jeonse deposits hitting record highs and the move-in rate for new apartments falling below 60% due to strict loan curbs.

Seoul Prices Hit 83-Week High While Gangnam Cracks Under Tax Pressure

Top developments

Seoul apartment prices rise for 83 consecutive weeks despite transaction freeze

According to the Korea Real Estate Board's data released on September 10, Seoul apartment prices rose by an average of 0.20% in the first week of September, marking the 83rd consecutive week of gains since February 2025. The upward trend is primarily concentrated in mid-to-low-priced homes (under 1.5 billion won) and northern districts like Gangbuk and Dobong, where demand remains robust despite a sharp decline in transaction volume. This divergence highlights a market where "underpriced" assets are still absorbing liquidity while high-end segments face headwinds.

Gangnam, Seocho, and Songpa turn downward as tax overhaul swells listings

For the first time in 21 weeks, Songpa-gu apartment prices declined, joining Gangnam-gu and Seocho-gu which have now fallen for five straight weeks. Listings in these key districts jumped more than 20% following the government's announcement of a tax reform plan that increases the burden on high-priced homes, prompting owners to sell before new regulations fully take effect. This shift is narrowing the overall gain in Seoul, as the cooling in the wealthy southern districts counterbalances the gains in the north.

August move-in rate falls below 60% amid loan curbs

The move-in rate for newly built apartments in Korea dropped to 59.5% in August, the first time it fell below the 60% threshold in recent months, according to data reported on September 10. Tighter household lending rules, particularly the stress DSR (Debt Service Ratio) implementation, have left many buyers unable to secure balance loans required to complete their purchases. This bottleneck is creating a backlog of unsold inventory and delaying revenue recognition for homebuilders.

Seoul officetel jeonse deposits hit record high since 2011

As apartment listings shrink and prices remain high, demand has shifted toward officetels, driving their jeonse deposits to an average of 237.37 million won in August, the highest level since 2011. This record high indicates that renters are increasingly willing to lock up large sums in smaller, alternative housing types rather than paying monthly rent or attempting to buy apartments. The trend underscores the continued pressure on the rental market despite government efforts to stabilize prices.

Local view

Local media outlets are highlighting the stark divergence between Seoul's districts and the broader national slowdown. Money Today reports that while listings are increasing due to the revival of capital gains tax for multi-homeowners, actual transactions are freezing because buyers and sellers are waiting for the final details of the tax reform plan. Donga Ilbo notes that the top 10 areas for price growth over the past 83 weeks are all in Seoul and Gyeonggi-do, with local regions outside the capital continuing to see price declines. Kyunghyang Shinmun emphasizes that the downward turn in Songpa-gu is a significant signal that the "bubble" sentiment in the three most expensive districts (Gangnam, Seocho, Songpa) is finally breaking under regulatory pressure.

Context & numbers

• Weekly Price Change (Sept 1st Week): Seoul +0.20%, Nationwide +0.08%.
• Jeonse Price Change: Nationwide jeonse prices rose 0.10% in the first week of September.
• Transaction Volume: Seoul apartment sales transactions in August totaled 2,887, a roughly 50% drop from previous peak periods.
• Presale Outlook: The September presale outlook index fell 6.9 points to 86.3, indicating negative sentiment among homebuilders.
• Move-In Rate: Dropped to 59.5% in August due to loan restrictions.

On the radar

• Policy Finalization: Buyers and sellers are closely watching for the finalized details of the tax reform plan announced in early September, which could further alter listing behavior in Gangnam and Seocho.
• DSR Impact on Delinquency: A Bank of Korea report suggests that households with a Debt Service Ratio above 46% significantly cut spending when rates rise, with delinquency rates rising 0.81 percentage points for heavily leveraged buyers per 1% rate hike; this may influence future loan approval strictness.
• Jeonse Fraud Concerns: Recent explainer pieces highlight that the traditional jeonse system is increasingly seen as a breeding ground for fraud, potentially leading to stricter oversight or a faster decline in its usage.
