Seoul’s Housing Ladder Still Starts With Wealth

Korea’s 2026 property-tax proposal would favour owner-occupied homes and raise the cost of high-value, non-resident and multiple holdings. The larger barrier appears earlier, when buyers bring equity from property, family capital and debt.

Only about 7 per cent of homes in Seoul were within reach of a median-income family in 2025, assuming the household used its own capital and standard mortgage finance while keeping repayments below one quarter of income. The comparable share was 32 per cent in 2012. Over thirteen years, ownership in the capital moved beyond the purchasing capacity produced by ordinary wages and savings, leaving a growing part of the market to households arriving with proceeds from another home, financial help from relatives or enough existing wealth to meet a large deposit without relying heavily on a mortgage.

The government’s property-tax proposal, announced on August 3 and still subject to legislation, takes aim at advantages inside that ownership market. A household living in the only home it owns would receive a larger deduction under the comprehensive real estate holding tax, while a household owning the same single property but living elsewhere would receive less. Other owners would have their relief linked partly to the share of their housing wealth represented by the home they occupy. Capital-gains deductions would also shift towards years of residence, with monetary ceilings introduced for exceptionally large gains, and older long-term residents facing a heavy annual bill relative to income would gain wider access to tax deferral.

The changes give actual residence more weight and reduce the protection attached to expensive homes held without occupation. They also recognise that one extremely valuable apartment can contain more wealth than several modest regional properties. Yet the larger owner-occupier deduction becomes available only after a household has accumulated the deposit, passed the bank’s lending test, paid the acquisition tax and completed the purchase. By that point, the divide between the buyer carrying equity from an earlier property and the buyer relying on income has already shaped the transaction.

Sales by multiple-home owners may add properties to the market, though the economic result depends on the transactions that follow. A tenant may buy the released home and enter ownership. An existing owner may replace one apartment with another. The seller may repay debt or leave housing altogether, or may combine the proceeds from several properties to compete for one more valuable Seoul residence. Each path produces a different distribution of housing wealth even when the official count of multiple-home owners falls.

Relief after the purchase

Under the proposal, the assessed-value deduction for an owner-occupied principal residence held by a one-home household would rise from KRW 1.2 billion to KRW 1.4 billion. A one-home household living elsewhere would receive a KRW 900 million deduction, while other individual owners would begin with a smaller amount and receive additional relief according to the proportion of their housing portfolio represented by the occupied home. The recurrent tax changes would begin in 2027, followed by a two-stage revision of capital-gains deductions from 2028. By 2029, the long-term deduction on a principal residence would depend on years of occupation rather than the length of time for which the title had merely been held.

Government simulations show modest annual savings around the lower end of the affected owner-occupied market and sizeable increases as the value of the residence moves into the highest price bands. New ceilings on capital-gains deductions would further reduce the absolute benefit available to owners whose properties produced very large gains. The package therefore contains both relief and heavier taxation, distributed according to residence, value and the size of the realised profit.

The political defence of owner-occupier relief often centres on a pensioner who bought decades ago and now lives on a modest income in a neighbourhood transformed by rising prices. That household exists, although research on the people already above the previous tax threshold gives a different picture of the typical case. In 2024, 85.9 per cent of owner-occupier households with one home assessed above KRW 1.2 billion lived in Seoul. Their apartments were worth more than KRW 2.4 billion on average and had been held for close to eleven years; 60.2 per cent of the households belonged to the highest income decile and 74.1 per cent to the top fifth.

Averages cannot describe every owner’s capacity to pay. Debt, medical costs, family obligations and the absence of liquid savings can leave a household under pressure despite a valuable property. The government’s expanded deferral provision addresses that pressure more directly than a permanent deduction. An owner aged at least 65 who has lived in the home for ten years or more could qualify when the combined annual property-tax bill reaches at least 10 per cent of the previous year’s income, allowing the liability to remain against the asset until a later sale or transfer.

The larger basic deduction extends further. It reduces the tax base for qualifying owner-occupiers regardless of salary, financial wealth or immediate access to cash, granting the same form of relief to a high-income household and a pensioner living in similarly valued homes. Deferral protects the resident’s ability to stay while preserving the public claim on the property; a deduction removes part of that claim each year. Offering both instruments broadens the political reach of the plan, while weakening the connection between the permanent saving and the liquidity problem used to justify it.

Geography shapes the distribution as strongly as income. An assessed-value threshold of KRW 1.4 billion has little practical relevance to most homeowners in Busan, Daegu or other regional cities. In Seoul, where expensive apartments account for a much larger share of the market, it protects a recognisable group of owner-occupiers. The provision is national in law and concentrated in effect.

A renter competing for one of those apartments receives no equivalent help with the initial equity requirement. Annual relief follows registration and occupation; the purchase price comes first. An owner who entered the market years earlier can retain the appreciation, use the apartment as collateral and carry the equity into a later move, while the new buyer must cover the same market value from current savings, family resources and debt.

Several homes, one more valuable address

Consider a household holding two regional apartments and a smaller property in the capital region. Higher recurrent taxation and the prospect of less favourable treatment may lead it to sell. The proceeds can be used to reduce leverage, though they can also be pooled into the purchase of one Seoul apartment that becomes the household’s principal residence. Three titles become one, and the recorded number of multiple-home owners declines, while the household’s exposure to the strongest housing market remains intact.

The government has built safeguards against the most aggressive form of consolidation. Total housing value would carry more weight in the recurrent tax schedule, and exceptionally valuable residences would face higher bills. Capital-gains relief would be capped, preventing the largest realised profits from receiving an unlimited percentage deduction. These changes narrow the gap between one ultra-expensive home and several lower-valued properties.

The attraction of a principal Seoul residence nevertheless extends beyond its tax treatment. Large complexes produce frequent comparable sales, banks recognise the collateral readily and buyers can observe the price history in detail. Employment, schools, transport and professional networks support a deeper pool of future demand. A regional apartment held for rental or appreciation may carry a lower nominal price, yet its value depends more heavily on a local population and economy that have weakened relative to the capital.

Selling into that market can encourage further concentration. An owner in Busan may accept a price still below the previous peak, then take the liquid proceeds to a Seoul market that has already recovered. Once the new apartment becomes the household residence, the owner receives the tax treatment attached to occupation. The transaction moves capital between cities even though the physical home sold in Busan stays where it is.

Public transaction files reveal the contract price, date, floor area and location of both properties. They cannot show that the same household completed the two transactions or how much debt was repaid between them. Anonymised links across tax, ownership and mortgage records would allow researchers to follow the sequence without exposing individual identities: sale of the additional homes, disposal of the proceeds, purchase of a replacement residence and the resulting change in total housing wealth.

The purchaser of the released property determines whether ownership widens. A tenant buying the home in which the family already lives gains a durable asset and leaves the rental market. A household selling one property to buy another merely changes its address. Transactions through spouses, relatives and companies can also preserve economic control while altering the ownership categories visible in aggregate statistics.

Local demand decides whether the new listing creates a genuine opportunity. A well-located apartment in Busan may attract a first-time buyer at a price supported by local income. Another unit in a peripheral development with weak employment access may sit unsold or clear only after a substantial reduction. Counting both as investor-owned homes returned to the market conceals the different role each plays in the regional housing system.

A lower count of multiple-home owners can therefore accompany several outcomes: broader ownership, weaker rental supply, falling regional collateral or stronger concentration in Seoul. The tax return records the number of titles. The balance sheet records where the value went.

Korea charges most when a home changes hands

Property taxation in Korea is already high by international standards. Revenue from property-related taxes equalled 3.0 per cent of gross domestic product in 2024, compared with an OECD average of 1.6 per cent, and supplied 11.7 per cent of the country’s total tax revenue. Half of that property-tax revenue came from taxes on transactions, while recurrent taxes on immovable property supplied 29.4 per cent. Across the OECD, recurrent taxation accounted for approximately 56 per cent.

The composition places a large obligation at the moment a household buys, sells or transfers an asset. Acquisition tax on an ordinary home generally ranges from 1 to 3 per cent according to the taxable value, with higher charges applying to some additional purchases. Brokerage, registration, financing and moving costs arrive alongside it, drawing from the money available for the deposit and increasing the cash required before the household receives any housing service from the new property.

Annual property taxes follow a different timetable. Local property tax and, above the relevant threshold, the comprehensive real estate holding tax are distributed across the holding period. Assessments, deductions, statutory ratios, credits and limits on annual increases reduce or delay parts of the bill. A valuable home can remain in the same hands while the owner waits for a favourable sale, finances the annual charge from income or borrows against the property.

The contrast affects ordinary movement throughout a household’s life. An older couple may continue occupying a large apartment after their children leave because downsizing requires another taxable purchase. A family needing more space may postpone the move until the expected improvement justifies the transaction cost. A worker considering a job in another city must compare the higher wage with the expense and uncertainty of selling one home and buying another.

When a household finally moves, a small improvement can appear uneconomic. The same acquisition tax and brokerage process applies whether the buyer gains a modest advantage or secures a home expected to remain useful and marketable for many years. Buyers therefore have reason to wait, assemble more capital and aim for a property with stable demand, transparent prices and a deep resale market.

Korea’s apartment complexes meet those requirements more effectively than most other forms of housing. Units of the same floor area share the land, building age, management, school district and transport access. A transaction in one 84-square-metre apartment can be compared immediately with earlier contracts in the same complex and with matching units nearby. Detached houses and small multi-family buildings contain more variation in land, condition, legal status, access and maintenance history, leaving the next sale harder to price.

Public transaction reporting strengthened the difference. A completed apartment sale supplies a visible reference to owners, brokers, buyers, appraisers and banks. The contract may have involved a renovated interior, a favourable view or a seller under unusual pressure, and a later cancellation may alter the record. During a rising market, however, one new high can lift asking prices throughout the complex before enough later contracts confirm that the level is sustainable.

Banks follow the same information. At the end of 2024, households and companies owed KRW 1,932.5 trillion in funds supplied to the real-estate sector, an amount equal to about half of all private credit. Property offers collateral whose value can be observed and recovered more readily than the future earnings of a small company or the commercial potential of an untested technology. Standardised apartments provide the clearest household collateral within that system.

A higher transaction price increases the apparent equity of neighbouring owners. That equity can be realised through a sale, used for refinancing or carried into the deposit on another apartment. The next lender observes the revised comparable price, and the next buyer enters negotiations from the new reference point. Bank of Korea research found that housing prices and household debt rose gradually after an increase in price expectations, with the strongest response appearing seven to eight months later.

Jeonse added financing outside the conventional mortgage. A tenant transfers a large refundable deposit to the landlord and pays little or no monthly rent. The deposit can help the tenant control monthly housing costs, while also allowing the landlord to purchase a property with less personal equity. When prices rise, the return on the owner’s capital is magnified; when prices or deposits fall, the obligation to return the tenant’s money remains even if the home can no longer be sold at the expected value.

Mortgage restrictions reduce some of that leverage and protect the banking system. Their distributional effect changes as the permitted loan becomes small relative to the purchase price. A household with a stable salary but little wealth may pass an income test and still lack the equity needed to complete the transaction. Another buyer carrying proceeds from an earlier home or assistance from parents can proceed with a much smaller mortgage.

The resulting market can hold less debt per expensive transaction while relying more heavily on accumulated wealth. Banks gain protection from highly leveraged borrowers; entry shifts towards buyers who already possess property, financial assets or family capital. Tax relief for an owner-occupied residence begins after this allocation of credit and equity has selected who can buy.

Seoul recovered. Busan’s collateral did not

The recent national housing cycle separated sharply by region. From January 2024 to October 2025, Seoul’s transaction-based housing-price index rose 18.2 per cent, while the non-capital region declined 2.0 per cent. By November 2025, Seoul’s apartment-price index stood 2.1 per cent above its previous peak. Busan remained 18.0 per cent below its own, Daegu was 26.6 per cent lower and the five major regional cities as a group remained 13.0 per cent below their earlier highs.

Price indices do not reproduce the gain or loss on every apartment. They do show the recovery of collateral available to the next transaction. A Seoul owner selling in late 2025 entered the market with an asset class that had regained its earlier peak. A Busan owner seeking to buy in Seoul faced a weaker sale price at home and a stronger purchase price at the destination, leaving more of the difference to be covered through savings, borrowing or family transfers.

Housing value and credit have concentrated in the same market. Seoul apartments represented 43.3 per cent of the total value of apartments nationwide by November 2025, slightly above the previous record share. Seoul also accounted for 34.2 per cent of household lending by deposit-taking institutions at the end of the third quarter. A city containing less than one-fifth of the national population carried far larger shares of apartment wealth and household credit.

The regional distance had opened well before the latest recovery. The median Seoul apartment cost 2.22 times the median apartment outside the capital region in 2014, according to analysis by the National Assembly Futures Institute. The multiple reached 4.62 in 2021 and remained 4.29 in 2025. Differences in the homes sold each year prevent that ratio from serving as a matched comparison of equivalent properties, although the direction is clear: ownership outside the capital has lost purchasing power against Seoul.

A lower-priced Busan home still provides shelter, local security and protection from rent. Its weakness emerges when the owner tries to use it as capital for a move towards the country’s most concentrated labour market. Employment, universities, corporate functions and professional networks remain heavily weighted towards the Seoul Metropolitan Area, where housing consumes a larger share of the resources required to take advantage of those opportunities.

Migration towards the capital can improve income prospects, yet the ability to relocate is distributed through family wealth as well as individual skill. Parents who own property in Seoul can release equity, provide a deposit, pledge collateral or transfer the asset later. A family whose main property is a regional home still below its previous peak has less to mobilise without weakening its own housing security. The child may secure the same job and face a much larger capital gap before living within a reasonable distance of it.

The market separation also creates opposite financial risks. Seoul faces renewed price expectations, scarce accessible supply and a banking system repeatedly drawn towards high-value collateral. Busan and other regional cities face declining collateral, completed but unsold homes and construction firms exposed to local demand that did not materialise. Further price declines can leave more borrowers with mortgages approaching or exceeding the value of the property and weaken lenders concentrated in regional housing and development finance.

Housing supply has to respond to those differences. Seoul’s stock remains tight relative to demand, and more than half of its apartments are over twenty years old, adding pressure for redevelopment in already expensive districts. Busan can have vacancies alongside demand for better housing because the available units are poorly located, ageing or disconnected from employment and services. Another peripheral development may increase the official supply while drawing residents and spending away from existing neighbourhoods.

The national tax proposal lands on both markets through the same legal categories. A larger deduction for an owner-occupied home near the national threshold offers substantial protection to a Seoul asset with strong collateral and resale capacity. Most Busan homeowners sit far below that threshold. Higher charges on additional properties may release regional homes to local buyers, while also encouraging the seller to transfer the resulting capital to Seoul.

The property remains in Busan after the sale. The proceeds do not.

The next owner

A durable property-tax system would reduce the cost of ordinary movement while keeping valuable assets within a predictable annual tax base. Acquisition taxes could fall gradually for first purchases, replacement moves and downsizing as recurrent taxation becomes more stable. Cutting transaction charges before annual taxation and supply adjust would release extra bidding power into Seoul; raising recurrent taxes without a transition would place abrupt pressure on households whose cash income has not followed their home’s assessed value.

Deferral provides the cleaner response to that liquidity problem. A resident whose annual bill exceeds a defined share of income can remain in place while the liability accumulates against the property. Similar arrangements elsewhere treat the government’s payment as a loan secured on the home rather than a permanent exemption. The timing of collection changes, while the tax attached to substantial property wealth survives until sale or transfer.

First-time buyer assistance needs the same attention to where public support ends up. Larger mortgages help individual households bid more, but a broad expansion of credit in a constrained market gives sellers access to the subsidy through higher prices. Shared-equity assistance can lower the initial capital requirement while allowing the public contribution to participate in the later gain, providing a route into ownership without transferring the entire benefit to the first seller.

Rental housing and vacancy require separate treatment. A second apartment offered under a stable long-term tenancy provides a housing service even when its owner lives elsewhere. Relief can depend on verified contracts, limits on deposit leverage, maintenance standards and compliance with rent rules. A habitable home left empty in a high-demand Seoul district presents a different use of scarce property, while an abandoned building in a shrinking Busan neighbourhood may have no tenant at any price and require conversion, public acquisition or demolition.

Regional housing policy cannot continue to treat unit construction as a universal measure of success. Seoul needs accessible homes near jobs and high-capacity transport, with public land and development rights used to preserve affordability beyond the first purchaser. Busan needs to concentrate renovation, housing conversion and public services around neighbourhoods where employment and population can support them. Housing value in a regional city becomes durable when residents expect to remain, rather than when another development briefly adds construction spending.

The effect of the 2026 tax plan can be measured through records the government already holds. Ownership data can show whether homes released by multiple-property owners went to households buying for the first time. Tax and registration records can follow sellers who later acquire another home, revealing whether the proceeds left property, repaid debt or reappeared in a more valuable Seoul residence. Matched transaction data can track the price of comparable Busan and Seoul apartments, showing whether a regional home retains enough relative value to finance movement between the two markets.

Those results will take longer to emerge than the first wave of listings. Sales completed before a deadline may simply have been brought forward from later years. The mature effect will appear after households choose the property they intend to retain and the capital released by the transition has settled into its next asset.

The government has corrected genuine weaknesses in the existing system. Residence will matter more, costly non-resident ownership will receive less protection, extremely large gains will face limits and cash-poor long-term residents will have wider access to deferral. These changes improve the classification of people who already own property.

A Busan apartment sold by a multiple-home owner may soon be registered to a family that previously rented, giving that household its first durable claim on housing wealth. The same sale may finance the seller’s purchase of a more valuable Seoul residence. Both transactions reduce the former owner’s property count by the same amount. Only one widens access.

The new registry entries will show what the tax plan achieved.
