■ Survival buying of ultra-small apartments: With a shortage of jeonse (a lump-sum deposit lease) and monthly-rent units coinciding with soaring rents, demand for "survival buying" — purchasing a home even if it means settling for less space — is heating up the market for ultra-small apartments. From January to September this year, the average transaction price for Seoul units of 40 square meters or less in exclusive floor area rose 15.9% from a year earlier to 459.89 million won. For units of 20 square meters or less, the increase reached 29.7%, nearly triple the pace of other size brackets.
■ Calls for higher density in third-phase new towns: President Lee Jae-myung has called for raising floor area ratios in the third-phase new towns, giving momentum to discussions on expanding housing supply in the greater Seoul area. One analysis found that raising the average floor area ratio across the six third-phase new town districts from 194.1% to 300% would allow for an additional 63,677 homes. The speed of land compensation and permit approvals will determine whether the plans translate into actual construction starts and move-ins.
■ Worsening mortgage conditions for young adults: From January to August this year, the average loan-to-value ratio on mortgages taken out by young adults fell to 56.2% from 58.7% a year earlier, a drop of 2.5 percentage points and the first decline since 2022. With home prices rising and lending rules tightening, the average approved amount per loan increased even as the share of the collateral value covered by the loan shrank — a paradoxical outcome.

1. As Rentals Dry Up, "Survival Buying" Spreads; Gangnam Sees String of Deals Above 2 Billion Won
Key summary: As the shortage of jeonse and monthly-rent units and rising rents persist, buying demand is shifting sharply toward ultra-small apartments of 40 square meters or less in exclusive floor area. The monthly rent price index for Seoul units of 40 square meters or less climbed 8.19% to 103.19 in September this year from 95.38 last December. Transactions of 1 billion won or more jumped 41.5% to 375 from 265 during the January-September period. High-priced deals are spreading beyond the Gangnam area, including a 39-square-meter unit at Helio City in Songpa District that sold for 2.1 billion won in July and a 35-square-meter unit at Trimage in Seongdong District that sold for 2.07 billion won in January. With the average transaction price for ultra-small units of 20 square meters or less up 29.7%, the options are narrowing for owner-occupier buyers looking for relatively affordable homes.
2. Higher Density for Third-Phase New Towns Could Add Up to 63,000 Homes
Key summary: President Lee Jae-myung's call for raising floor area ratios in the third-phase new towns has pushed the expansion of housing supply in the greater Seoul area into full discussion. Korea Land & Housing Corporation (LH) reported that raising the current average floor area ratio of 206% to 250% or higher would add 30,000 to 40,000 homes, while the Korea Urban Real Estate Association analyzed that a rise to 300% could secure 63,677 homes. Lee left room for further increases, saying that floor area ratios should be raised even higher near railway stations and along arterial roads. The approach is drawing attention as a realistic alternative because it would increase supply without new land development, though observers continue to note that it must be accompanied by expanded infrastructure, including metropolitan transit networks, schools and parks.
3. Young Adults Falling Short on Mortgages; LTV Drops for First Time Since 2022
Key summary: From January to August this year, the average loan-to-value ratio on mortgages taken out by young adults fell to 56.2% from 58.7% a year earlier, down 2.5 percentage points and turning lower for the first time after three consecutive years of increases. The average approved amount per loan rose 7% from a year earlier to 255 million won, extending gains for a fourth straight year, yet the share of the collateral value covered by the loan declined. The loan-to-value ratio on first-time home purchase mortgages also fell sharply, to 65.8% this year from 71.8% last year, a drop of 6.0 percentage points. Financial industry officials have raised the possibility that income polarization has concentrated lending among higher-earning young adults while lower-earning ones have failed to clear lending thresholds.

4. 33㎡ Unit in Nowon Fetches 800 Million Won as Ultra-Small Apartments Catch Fire
Key summary: The average transaction price for Seoul ultra-small apartments of 40 square meters or less in exclusive floor area rose 15.9% from a year earlier to 459.89 million won during the January-September period, while transaction volume increased 21.6% to 4,985 from 4,101. High-priced deals have followed in non-Gangnam districts as well: a 33-square-meter unit at Misung in Wolgye-dong, Nowon District, sold for 820 million won in August, and a 39-square-meter unit at Hongje Station Harrington Place in Seodaemun District sold for 975 million won in July. With both jeonse deposits and monthly rents rising, more households are shifting to purchases, and the flow of owner-occupier buyers with limited funds into small apartments is expected to continue for some time.
5. Seongsu District 2 to Pick Builder Next Month; DL E&C Proposes "Acro Seongsu"
Key summary: DL E&C (375500.KS) has proposed its high-end brand "Acro Seongsu" for the redevelopment of District 2 in Seoul's Seongsu Strategic Redevelopment Zone. The project calls for nine buildings ranging from six basement levels to a maximum of 62 floors above ground, with a total of 2,350 homes and construction costs of 2.0137 trillion won. The builder will be decided at a general meeting of the redevelopment association on the 21st of next month. District 2 is the last of the four districts in the Seongsu Strategic Redevelopment Zone to go through the builder selection process. Acro-branded complexes have shown a marked rise in asset value, with a 234-square-meter unit at Acro River Park trading at 18 billion won in August 2024 and a 273-square-meter unit at Acro Seoul Forest at 29 billion won in June last year.
6. Flood-Prone Sangdo-dong to Be Reborn as 1,800-Home Complex up to 35 Stories
Key summary: The Seoul Metropolitan Government has finalized its fast-track plan for a housing redevelopment project in the area around 201 Sangdo-dong, Dongjak District. The plan would transform an aging low-rise residential area near Jangseungbaegi Station on Subway Line 7 into a residential complex of about 1,800 homes rising up to 35 stories, while also addressing disaster risks such as retaining wall collapses and flooding. With roughly 10,000 homes planned for development in the area, including the widening of Seongdae-ro to a four-lane, 17-meter-wide road, improvements to living infrastructure across the broader Sangdo area are expected to accelerate.
