seoul's residential landscape is rapidly shifting to a rent-centric city, marking the end of the decades-long charter system. this shift is more than just a supply-demand imbalance in the market; it is the result of a paradigm shift in financial policy, tax reform, supply shortages, and a fundamental shift in residential culture. this report presents the statistical evidence of Seoul's transformation into a renting city and delves deeper into the structural factors and social impacts behind it.
1. the acceleration of renting as seen through the statistics of Seoul's rental market transformation
renting is no longer the dominant form of tenure in Seoul's residential market. According to finalization date statistics from the Court Registration Information Plaza, the city's rental contract structure has already reached a historic turning point in 2022. from January to October 2020, the number of rental contracts signed in Seoul was 239,888, while in the same period in 2025, the number of rental contracts was 476,634, a nearly twofold increase in exactly five years.
on the other hand, rental contracts are losing ground in the market, dropping from 341,977 to 262,500 in the same period, a decrease of about 23% [Material]. the share of monthly rentals in total rental transactions reached 53.2% in 2022, overtaking subletting for the first time, and now stands at over 60% in 2025.

2. analyzing the three key factors that led to the collapse of the rental system
the shifting interests of landlords and tenants, as well as structural pressures from government policy, are behind the faltering charter system. this is more than just a matter of price, it means that the foundations of the housing finance system are crumbling.
first, there's the changing profit structure of landlords and the shifting burden of holding taxes. in the past, under low interest rates, rental deposits were an interest-free source of financing, but rising interest rates and tightening taxes have eroded this incentive. Under the Moon Jae-in administration, the comprehensive real estate tax rate for multiple dwellings was raised to up to 6%, and the fair market value ratio was gradually increased, pushing the holding tax burden on landlords past a critical point. As a result, landlords are increasingly looking to convert sublets to rents and pay the taxes out of the cash flow they generate each month.
secondly, tenants' lack of access to rental loans and fear of rental scams. with rental deposits skyrocketing and financial institutions tightening regulations on rental loans, underfunded tenants are being forced into the rental market. The aftermath of rental scams, especially the Villa Wang scandal, which has become a social issue in recent years, has also pushed tenants to prefer renting without the risk of losing their deposit.
thirdly, the impact of the Rent 3 Act and the use of contract renewal rights has led to a locked-in market. the use of contract renewal claims has led to a shortage of supply as rental units that should be on the market have not been rotated, creating a situation where tenants who need to sign new contracts are unable to afford the skyrocketing rental prices and opt for flipping or renting.
3. lending restrictions and the butterfly effect of policy 6.27 and 10.15 measures
the government's recently announced real estate measures are further accelerating the gentrification of the rental market by stifling liquidity in the charter market and blocking home purchase demand.
6.27 Measures lowered the loan-to-value ratio from 90% to 80% to stabilize household lending. this means that banks will directly bear the risk for 20% of the loan, which has led to tighter loan screening and reduced limits.
for example, for a 500 million won rental contract, the amount a tenant can borrow is about 40 million to 50 million won less than before the regulation. for young people and single-person households with limited financial resources, this increased cash burden is a decisive barrier to entering the rental market.
in addition, the 10.15 measures have blocked so-called gap investments by grouping all 25 wards of Seoul and major areas of Gyeonggi Province into regulated areas and expanding the designation of land transaction permit zones. the tightening of the residency obligation has eliminated the private source of supply that used to supply the market with rental properties. Add to this the reduction in LTV to 40%, and buyers who are unable to purchase a home have been forced to remain in the rental market, causing a chain reaction of surging rental demand and rising prices.

while these tighter lending regulations may be positive in terms of household debt management, they are having a negative impact on the rental market, with the disappearance of private rentals and skyrocketing monthly housing costs.
4. the spread of gentrification beyond Gangnam to the rest of Seoul
seoul's gentrification is more than just a numerical change; it is also manifested in price polarization and the popularization of high-end rent. while KRW 1 million a month was once considered the preserve of luxury homes, the average monthly rent for an apartment in Seoul is now at an all-time high of KRW 1.43 million, according to the Korea Real Estate Agency.
the growth in ultra-high rent transactions is even steeper. from just 23 transactions in 2020, the number of transactions with monthly rents of KRW 10 million or more increased by nearly nine times to 212 by October 2025. Ultra-expensive complexes such as Galleriafore in Seongdong-gu have even seen iconic transactions with KRW 100 million in deposits and KRW 40 million in monthly rents.
what's even more concerning is that this high-priced rent trend is spreading beyond Gangnam 3 and Yongsan to the outskirts of Seoul. even in neighborhoods that used to be classified as affordable, such as Doksan-dong in Geumcheon-gu or Jungang-dong in Nowon-gu, transactions of between KRW 3 million and KRW 10 million per month for a private 84-square-meter unit are popping up.
examples of high rent transactions by major neighborhoods in Seoul (2024-2025)
area (Complex name) area deposit monthly rent features seongsu-dong, Seongdong-gu (Galleriafore) 241 sqm 100 million won 40 million won ultra-luxury residential complex doksan-dong, Geumcheon-gu (Lotte Castle 1st) 84 ㎡ (1.5 acres) kRW 10 million kRW 10 million case of high rent proliferation in outlying areas nowon-gu Jungang-dong (Gunyeong 3rd) 84㎡ (1,000 square meters) kRW 6,000 million kRW 3 million rising rents in education-preferred areas average apartment rent in Seoul - - 1.44 million won at an all-time highthis is happening because renting is the only alternative available to renters in the face of blocked loans and disappearing rental properties. increasing housing expenditures while income levels remain stagnant is reducing Seoulites' disposable income and lowering their quality of life.
5. supply and demand outlook for the next three years Declining supply and scarcity of rentals
experts predict that the next two to three years will be a real watershed for Seoul's rental market, with a key rationale being a sharp decline in the number of new listings. according to data from Real Estate R114, apartment move-in volume in Seoul is expected to fall by about 45.9%, from about 32,810 units in 2025 to 17,763 units in 2026, and will drop to the 10,000-unit level in 2027.
move-ins of newly constructed apartments are the largest source of supply of units to the rental market. typically, 30 to 50 percent of new units go to charter, and when the supply is reduced by less than half, the charter shortage will only intensify.
seoul apartment move-ins by year
year seoul move-in volume (households) year-on-year growth rate forecast 2025 32,810 - move-in volumes remain flat 2026 29,161-31.6
new construction supply begins to decline sharply 2027 10,000 (est.) -45% or more the charter market supply cliffthe supply cliff doesn't just drive up rental prices, it also encourages more existing rentals to convert to rent. in a supply-dominated market, contracts are more likely to be signed on the terms the landlord wants, and with lending restrictions tightening the sales market, the unhoused are forced to rent in areas with better transportation and education options, often at a higher cost.
6. social housing inequality and the housing cliff for young adults
seoul's gentrification is exacerbating housing inequality between generations and classes. For young adults and single-person households with low incomes, the era of KRW 1 million per month is an unbearable housing cliff.
statistics show that the average monthly rent for a studio in a newly built villa in Seoul has already surpassed KRW 1.05 million. on average, young adults aged 19-34 are spending about 35% of their income on rent. this is more than 30% above the economic threshold of 30%, which is the level at which housing cost burden compromises household security.
this high housing cost burden is a significant factor in preventing young adults from building assets. this is because while renting allows them to get their security deposit back and use it as seed money for asset building, rent is a consumable expense that disappears every month.
young adults who spend more than 35% of their income on housing are severely limited in their ability to save, which in turn leads to marriage abandonment, childbearing avoidance, and national social problems. on the other hand, wealthy individuals are taking advantage of the renting system to accumulate wealth, either by avoiding holding taxes or by investing their surplus security deposit in other assets to earn a profit.
7. conclusion and future challenges
the gentrification of Seoul's rental market has become an irreversible trend. while the unique system of chartering will not disappear completely, renting will firmly take its place in the mainstream rental market. In the midst of this structural change, Seoul is at a critical juncture to establish a new rental housing system.
in the short term, the city needs to deregulate housing products that can be quickly supplied, such as office buildings and urban living housing, and expand public rental housing to cope with the sharp decline in occupancy. It also needs to create financial support products for young people who suffer from restrictions on charter loans and expand tax credits for rent expenditures.
in order to prevent Seoul from becoming a city of rent inequality, we need reasonable rent calculation standards that are win-win for landlords and tenants, and a strong government will to stabilize housing costs. the design of a new housing policy that fits the era of the disappearance of rentals will determine the future of Seoul.
frequently Asked Questions (FAQ)
Q1. Why is the demise of subletting happening so quickly?
this is because landlords prefer renting to cover increased holding taxes such as the comprehensive real estate tax, and tenants are increasingly choosing to rent or reverse rent due to tightening regulations on charter loans and concerns about charter scams.
Q2. How much harder has it been to borrow money for a rental since the 6.27 measures?
as the rental loan guarantee ratio has been lowered from 90% to 80%, banks' loan screening has become more difficult, and the proportion of cash that tenants need to provide themselves has increased significantly. For a 500 million won rental house, about 50 million won of additional funds are required.
Q3. Are there any benefits for young people in the rent era?
it's important to keep an eye out for government loans or rent support programs for young adults. It's also important to check the requirements for rent tax credits at the end of the year to ease the burden of housing costs.
Q4. Will Seoul apartment prices increase in the future?
the supply of apartments in Seoul is expected to plummet to half of its current level by 2026, so the upward pressure on prices from the lack of rental supply is likely to continue for some time.
Q5. Isn't high rent a problem in certain neighborhoods?
no. The phenomenon of high-priced rents is spreading across Seoul, with transactions of KRW 3 million or more per month becoming commonplace even in areas outside of Seoul, such as Geumcheon-gu and Nowon-gu, which used to be centered in Gangnam.
key takeaway: Seoul has transformed into a rent-centric city with a plummeting share of rentals and over 60% of transactions being rented. this shift, coupled with lending restrictions and a lack of supply, is leaving behind the challenges of rising housing costs and rising inequality.
