Assumptions for the Analysis — Establishing an Accurate Baseline for Seoul’s Housing Tenure Structure
Any discussion of Seoul’s housing policy must begin by fixing one basic reference point: the precise scale of owner-occupied households versus renter households. A synthesis of Statistics Korea and the Ministry of Land, Infrastructure and Transport’s housing surveys places the total number of households in Seoul at roughly 4.5 million (based on the registered census and the Ministry of the Interior and Safety’s resident-registration household count).【KOSIS (Statistics Korea), Population, Households, and Housing Census】
The tenure breakdown is presented as follows: owner-occupied about 44%, jeonse about 25%, and monthly rent about 28% (Ministry of Land, Infrastructure and Transport / Statistics Korea, Housing Survey). Converted into household counts, the structure becomes clear: owner-occupied households: 4.5 million × 44% ≈ 2.0–2.1 million; jeonse and monthly-rent households: 4.5 million × 56% ≈ 2.4–2.5 million.
Accordingly, Seoul’s baseline structure is approximately 2.1 million owner-occupied households and about 2.4 million jeonse and monthly-rent households. This baseline is the point of departure for all analysis that follows.【Ministry of Land, Infrastructure and Transport / Statistics Korea, Housing Survey】
The Core Composition of the 2.4 Million Renter Households — The Weight of Single-Person Households
Within the 2.4 million renter households, single-person households account for a decisive share. According to the registered census, Seoul has about 1.66 million single-person households, representing roughly 39–40% of all households.【KOSIS (Statistics Korea), Households by Household Size】
The homeownership rate for single-person households is presented at roughly 30–32%.【Statistics Korea, One-Person Households in Statistics 2025】 Applying this ratio yields: single-person owner-occupied households: 1.66 million × 32% ≈ 530,000; single-person jeonse and monthly-rent households: 1.66 million − 530,000 ≈ 1.13 million.
In other words, of the 2.4 million jeonse and monthly-rent households, about 1.13 million are single-person renter households. The remaining roughly 1.27 million are renter households with two or more members. This structure places a decisive constraint on any discussion of homebuying capacity in Seoul, because single-person households are disadvantaged relative to multi-person households in income, assets, and debt-repayment dynamics.
The Income and Asset Reality of Renter Households
Combining Statistics Korea’s Household Finance and Welfare Survey with One-Person Households in Statistics 2025 produces the following averages for single-person households. Average annual income is about KRW 34 million, and average assets are about KRW 220 million.【Statistics Korea, Household Finance and Welfare Survey / One-Person Household Statistics】
These assets include jeonse deposits, small-scale financial assets, and other tangible assets. For jeonse and monthly-rent households, a substantial portion of assets is already tied up in residence-related funds such as jeonse deposits. Liquid assets that can be deployed immediately for a home purchase are often far below the average.
Renter households with two or more members likewise display a large asset gap compared with owner-occupied households, and only a limited share of households possess both sufficient upfront equity and the ability to service long-term debt simultaneously.
What It Actually Takes to “Buy a Home”
To purchase an owner-occupied home in Seoul, three conditions must be met at the same time. First, upfront equity on the order of hundreds of millions of won. Second, a stable income capable of supporting long-term loan repayment. Third, a credit and balance-sheet structure that can clear financial regulations such as DSR and LTV.
When these criteria are applied to the 2.4 million jeonse and monthly-rent households, it becomes clear that—even if home prices decline to some degree—a large-scale shift from renting to buying is unlikely. The constraint operates even more strongly among single-person households, which constitute nearly half of renter households.
The Size of the “Potential Buyer Group” Within the 2.4 Million Renter Households
One indicator for estimating an upper bound on purchasing capacity is the share of households with net assets of KRW 1 billion or more. The Household Finance and Welfare Survey places this group at roughly 10–12% of all households.【Statistics Korea, Household Finance and Welfare Survey】
However, this figure includes both owners and renters. If the focus is narrowed to renter households alone, the share falls further; even on a conservative estimate, it is likely below 5% of jeonse and monthly-rent households. Applied to 2.4 million renter households, the group that can purchase higher-priced homes without strain totals only about 100,000–120,000 households.
Even if the target price range is broadened to homes priced at KRW 500 million or more, the potential buyer group is unlikely to exceed roughly 300,000–400,000 households at most.
Absorptive Capacity Under a 540,000-Unit Sell-Off Scenario
Now consider a scenario in which 540,000 owner-occupied housing units held by 370,000 multi-homeowners are brought to market. Relative to the 2.4 million renter households, 540,000 units amount to about 22.5%. By the numbers alone, this may appear substantial.
Yet as shown above, only around 10–15% of the 2.4 million renter households have meaningful purchasing capacity. In other words, the structure is not one in which jeonse and monthly-rent tenants can absorb all 540,000 units.
Where the Actual Buyers Are Likely to Converge
The buyers who can realistically absorb these 540,000 units are likely to converge into a handful of groups: holders of financial assets of KRW 1 billion or more (estimated at about 476,000 people, based on consolidated financial-industry and media figures), higher-asset households that already own homes, “trade-up” demand from existing homeowners, and corporate or rental-purpose buyers.
In short, these units are likely to be absorbed not as an “exit” that stabilizes housing for the majority of renter households, but as a reconfiguration of ownership among those with the financial capacity to buy.
A Predictable Policy Conclusion
If one assesses the economic capacity of Seoul’s 2.4 million jeonse and monthly-rent households—particularly the 2.1 million households within that group referenced in the analysis—the outcomes of a forced sale of 540,000 units by multi-homeowners are largely predictable. First, most renter households cannot buy homes. Second, the supply released through sales will be absorbed primarily by upper-asset groups. Third, rather than resolving the housing problem, the likely result is a change in who owns the homes.
Closing — Re-centering the Focus of Housing Policy
Seoul’s housing challenge is not fundamentally a question of “how many homes can be forced onto the market.” The core reality is that more than half of Seoul households are not positioned, economically, to buy homes.
A sober look at the homebuying capacity of the 2.4 million jeonse and monthly-rent households leads to the conclusion that forced sales are unlikely to translate into housing stability. The focus of housing policy should shift away from sale pressure and toward building a structure in which households can live stably without having to own. That is the approach aligned with Seoul’s household structure and economic realities.
