What is the current average apartment price per square meter in Seoul compared to five years ago?
Seoul apartment prices have experienced dramatic growth over the past five years, rising from KRW 8.2 million per square meter in 2020 to KRW 13.4 million per square meter as of September 2025.
This represents a substantial 63% increase in apartment values across the Seoul metropolitan area. The price surge reflects both strong domestic demand and limited housing supply in desirable central districts.
Premium central districts like Gangnam now command KRW 25-40 million per square meter, while outer districts like Nowon remain more affordable at approximately KRW 9 million per square meter. The price differential between central and peripheral areas has widened significantly during this growth period.

How fast have prices been rising or falling annually over the past decade?
Seoul apartment prices have maintained consistent upward momentum over the past decade, averaging 7-8% annual growth with notable acceleration in recent years.
Between 2015-2020, price growth was relatively steady at 5-7% per year. However, the market experienced significant acceleration starting in 2020, with annual growth rates spiking to 13-18% in central areas during 2022-2025.
The most dramatic growth occurred in the last three years, with total price appreciation reaching 44% during this period. Some districts experienced even steeper increases, with year-over-year growth hitting 18% in premium areas during 2024-2025.
This growth trajectory significantly outpaced inflation and wage growth, making affordability a critical concern for first-time buyers and younger demographics.
What is the current rental yield in central Seoul versus suburban districts?
Seoul's rental market shows clear geographical yield variations, with suburban areas offering superior returns compared to expensive central districts.
The citywide gross rental yield averages 4.31% as of September 2025, representing a slight improvement from 4.29% recorded a year earlier. However, this average masks significant district-level differences.
Central premium districts like Gangnam and Seocho deliver lower yields of 2-3% due to their high property acquisition costs, despite strong rental demand from affluent tenants. Studios in these areas typically offer the best yields within the central market.
Emerging and suburban districts such as Mapo, Yongsan, and Nowon provide more attractive yields of 3.5-4%, combining reasonable entry prices with solid rental demand. Some outer districts can achieve yields up to 4.5-5%, making them appealing for yield-focused investors.
How many housing units are expected to be supplied annually over the next three years?
Seoul is planning substantial housing supply increases to address chronic shortages, with over 132,000 new homes expected by 2028.
This translates to approximately 26,000-28,000 new housing units per year across Seoul from 2025 through 2028. The supply program represents one of the most ambitious housing construction plans in the city's recent history.
At the national level, the government aims to supply 830,000 units by 2025 across the Seoul metropolitan region including Gyeonggi Province and Incheon, with the majority concentrated in the capital city.
The new supply focuses primarily on apartment developments, with government initiatives converting state-owned properties into residential units to accelerate delivery timelines.

What percentage of new developments are concentrated in Gangnam compared to other districts?
Gangnam district attracts a disproportionate share of high-value new developments, though precise percentages vary depending on measurement criteria.
Central and southern districts including Gangnam, Seocho, and Songpa receive the highest concentration of premium developments due to land values and buyer preferences. Gangnam typically attracts over 20-25% of high-value new supply projects.
However, Gangnam represents a minority of total housing units due to severe land constraints and high development costs. The district's limited available land restricts the absolute number of units despite attracting premium projects.
Most large-scale residential developments are occurring in outer districts where land availability and costs support higher unit volumes, while Gangnam focuses on luxury, smaller-scale projects with higher per-unit values.
How many foreign buyers have entered the market in the past year, and what share of total transactions do they represent?
Foreign buyers remain a minor presence in Seoul's residential property market, accounting for less than 5% of total transactions over the past 12 months.
While the absolute number of foreign buyers has increased compared to previous years, their market share remains limited due to South Korea's strict property purchase and lending regulations for non-residents.
Regulatory barriers include higher down payment requirements, restricted borrowing capacity, and additional tax obligations that discourage speculative foreign investment. These measures have been effective in maintaining domestic buyer dominance.
Most foreign purchases involve long-term residents or investors with established business presence in South Korea, rather than purely speculative international capital.
What is the current household debt-to-income ratio in South Korea and how does it affect property demand?
South Korea maintains one of the world's highest household debt-to-income ratios at approximately 201% as of 2025, creating significant constraints on property market demand.
| Debt Impact Category | Current Status | Market Effect |
|---|---|---|
| Household DTI Ratio | 201% (among world's highest) | Restricts borrowing capacity |
| First-time Buyers | Severely constrained | Reduced entry-level demand |
| Young Households | Limited access to credit | Delayed homeownership |
| Speculative Demand | Dampened by debt limits | Reduced investment activity |
| Transaction Volumes | Suppressed overall | Market liquidity concerns |
How have mortgage interest rates changed in the last 24 months, and what is the forecast for the next 12?
Seoul mortgage rates have risen substantially over the past 24 months as the central bank combat inflation through monetary tightening policies.
Current floating and fixed mortgage rates range from 3.65% to 7% depending on the lender and borrower profile, representing a significant increase from historical lows of 2.2-3% recorded in 2023.
The rate increases reflect the Bank of Korea's aggressive stance against inflation, with multiple rate hikes implemented throughout 2024 and early 2025. This monetary tightening has directly impacted property affordability and buyer demand.
Rates are expected to remain elevated through 2026 before potentially easing, depending on inflation control success and broader economic conditions. Any rate reductions will likely be gradual rather than dramatic.

What is the vacancy rate for newly built apartments in Seoul right now?
Seoul maintains exceptionally low vacancy rates for newly built apartments, reflecting strong underlying housing demand despite market cooling measures.
Central districts typically maintain vacancy rates under 2%, with premium new developments in Gangnam, Seocho, and Mapo often experiencing oversubscription during pre-sales phases.
Peripheral areas show slightly higher vacancy rates but remain well below levels that would indicate oversupply. The low vacancy environment supports rental income stability for property investors.
New apartment complexes benefit from modern amenities and energy efficiency features that attract tenants willing to pay premium rents, contributing to rapid lease-up periods.
How many property transactions were recorded last quarter compared to the same quarter last year?
Seoul property transaction volumes declined significantly in Q2 2025, falling 15-20% year-over-year compared to Q2 2024 levels.
The transaction decline reflects the cumulative impact of government cooling measures implemented in mid-2024, including stricter lending criteria and higher transaction taxes.
Reduced transaction activity primarily affects the speculative investment segment rather than genuine end-user demand, though first-time buyers also face increased barriers due to tighter credit conditions.
Lower transaction volumes have improved market stability but raised concerns about liquidity for property owners seeking to exit positions.
What is the projected population growth or decline in Seoul by 2030?
Seoul faces modest population decline projections through 2030, with demographic estimates suggesting a 2-3% reduction from current levels.
1. **Aging Demographics**: South Korea's rapidly aging population reduces household formation rates2. **Suburban Migration**: Young families increasingly move to surrounding Gyeonggi Province for affordability3. **Birth Rate Decline**: Among the world's lowest fertility rates limits natural population growth4. **Economic Decentralization**: Government policies encourage business relocation to secondary cities5. **Housing Costs**: High property prices drive residents to seek alternatives outside SeoulDespite population decline projections, housing demand may remain stable due to shrinking household sizes and preference for larger living spaces among remaining residents.
How much did government housing policy measures, like tax adjustments or loan restrictions, reduce transaction volumes in the past year?
Government cooling measures implemented in 2024 have significantly impacted Seoul's property market, reducing transaction volumes by 18-22% over the past 12 months.
The policy package included higher transaction taxes, increased capital gains tax rates, and stringent loan-to-value (LTV) restrictions designed to curb speculative activity and improve affordability for genuine buyers.
Loan restrictions have been particularly effective in reducing investor demand, with stricter DTI requirements limiting borrowing capacity for multiple property owners and speculative purchasers.
While transaction volumes declined substantially, the measures have achieved their intended goal of moderating price growth and reducing speculative froth in the market.
