the real estate market is undergoing an unprecedented structural transition in 2025. with strong government policies to curb demand intersecting with measures to expand supply, market participants must pay attention to the mixed signals from three variables: regulation, interest rates, and supply and demand imbalances. This report recaps the policy landscape in 2025 and provides an in-depth analysis of the extreme polarization and supply shocks that will unfold in 2026.
1. the policy underpinnings and regulatory framework of the real estate market in 2025
to understand the outlook for the real estate market in 2025, it is important to understand the organic relationship between the three key measures announced this year: the 6.27 Measures, the 9.7 Measures, and the 10.15 Measures. the government has been gradually increasing the intensity of regulations to manage household debt and stabilize the market, which has resulted in the isolation of liquidity in the market to certain regions.
6.27 The real estate measures were the first strong demand management measures announced after the new government took office. At its core, it capped mortgage loans in the metropolitan area and speculative hotspots at a maximum of KRW 600 million. By banning mortgages for additional home purchases, especially by multi-family households, it sought to block speculative demand and reorient the market toward real consumers. it also banned sub-rental loans conditional on ownership transfer to squeeze the funding stream of so-called gap investments.
9.7 The housing supply expansion plan recognized that curbing demand alone was not enough to catch the market, so it laid out a massive blueprint to build a total of 1.35 million housing units in the Seoul metropolitan area by 2030. The plan took a pragmatic approach, promising to manage the supply of housing units based on actual construction starts, rather than on the basis of past approvals. it included a policy of speeding up supply by allowing the Korea Land and Housing Corporation (LH) to develop public housing directly, while at the same time not loosening the reins on lending regulations, including reducing the LTV cap from 50 percent to 40 percent.
the most intense real estate measure, the 10.15 Real Estate Measures, designated 25 districts across Seoul and 12 key areas in Gyeonggi Province as adjustment target areas, speculative overheating zones, and land transaction permit zones, which is unprecedented in the country's history, and imposed a two-year residency requirement and strictly enforced financing source scrutiny on apartment purchases in these areas.

while the tightening of the regulatory framework temporarily curbed the price surge in Gangnam 3 and the Han River belt, it also triggered a ballooning effect, where demand was diverted to the off-plan and auction markets, which can avoid regulations.
2. analysis of hyperpolarization and ballooning in the apartment sales market
the most vivid keyword for the apartment market in 2025 is polarization. the price gap between Seoul and the provinces, and even within Seoul, between core and non-core areas, widened in line with the sentiment of preserving asset value.
According to KB Real Estate data, from January to November 2025, Seoul apartment sales prices rose by an average of 10.02 percent, but the five metropolitan areas showed a clear decoupling, with prices falling by 1.76 percent. Seoul's Seongdong District, in particular, recorded a phenomenal 21.39 percent increase, demonstrating the status of the Han River Belt. in the provinces, on the other hand, the market slowdown accelerated as unsold apartments piled up and demand disappeared.
this was due to investors' strategy of focusing on a single property amidst an uncertain economic outlook. As high interest rates remained high and loan availability shrank, investors funneled capital into core Seoul locations where there was less risk of asset depreciation. this had the paradoxical effect of strengthening demand in Gangnam and areas along the Han River as regulations tightened.

in addition, when the October 15 measures cordoned off much of Seoul as a land transaction permit zone, investors flocked to auction markets where there is no residency requirement. seongdong-gu's winning bid rate soared as high as 116 percent in August, illustrating the market's eagerness to snap up prime locations amid regulatory pressure.
3. lotto subscription phenomenon in the condominium market and trends in subscription rates
the condominium market also saw extreme skewing. Complexes in Seoul's Gangnam 3 and Yongsan districts, which are subject to a price cap, led the lotto subscription frenzy as they were guaranteed to fetch hundreds of millions to billions of won over the surrounding market price.
jamsil RL in Songpa-gu saw a record 631.6-to-1 competition ratio in the first round of subscription, with the expected market price difference for the winner alone analyzed to be over KRW 1.1 billion. cheongdam RL in Cheongdam-dong, Gangnam-gu, also highlighted the overheated subscription market, with residences selling for around KRW 4 billion more than the sales price.
however, if you look outside of Seoul, the picture is completely different. across the country, more than half of all units sold were unsold, and unsold apartments piled up, especially in less desirable areas of the country, amplifying financial risks for builders. this means that the subscription market has been thoroughly reorganized around asset value and location.

4. structural changes in the rental market: shortage of rentals and acceleration of rentalization
an integral part of the real estate market outlook for 2025 is the upheaval in the rental market. regulations imposed on the sales market have been transferred to the rental market, resulting in a shortage of rental units and rising prices.
the rise in rental prices has been particularly strong in Seoul and the core areas of the Seoul metropolitan area, where supply is scarce. gwacheon, Gyeonggi-do, saw a staggering 10.36 percent increase, driven by overlapping demand from rebuilding migrants. even in Seoul, sublet prices soared in neighborhoods with limited supply, such as Gangdong-gu and Songpa-gu, making housing more unaffordable for the masses.
a more serious phenomenon is the acceleration of subletting. landlords have shifted the burden of the enhanced holding tax to tenants, or preferred to rent to avoid the risk of interest rate fluctuations. the number of apartments for rent in Seoul has increased by about 9.6 percent year-on-year, and rental prices are rising steeply. this suggests that the foundations of South Korea's once rental-dominated housing market are shaking, a trend we expect to continue in our 2026 real estate outlook.
5. real Estate Market Outlook 2026: Supply Cliff and Demand Clash
in 2026, the real estate market is expected to face an even more severe supply shortage than in 2025. this is because the surge in construction costs and the project financing (PF) crisis that began two to three years ago is manifesting itself in the disappearance of move-ins.
seoul's housing completions index is expected to fall to 0.48, less than half of its normal level. this indicates an extreme supply-demand imbalance, where demand for new apartments remains high, but supply is not keeping up with it at all. at the same time, housing demand is likely to peak as the eco-generation of 30-somethings, numbering 740,000, enters the market in earnest.
table 4. Forecasted move-in volume in the metropolitan area and nationwide in 2026
category 2025 (units) 2026 (units) change (%) seoul Apartment Index 1.23 0.84-31.7
national Apartment Supply 27.80,000 21.10,000-24.1
planned move-ins in metropolitan areas 16.10,000 11.10,000-31.0
experts warn that this supply cliff will lead to a surge in rental prices and upward pressure on sales prices. although the government has promised to expand supply through the 9.7 measures, analysts believe that it will be insufficient to fill the supply gap in 2026, given the lag time between actual construction and move-in.
6. changing financial and tax environments and strategies for multifamily
looking ahead to 2026, the most important practical variable is the end of the capital gains tax deferral. at the end of the deferral, currently set for May 9, 2026, multifamily owners will face a significant tax burden.
for example, if a triplexer sells a home, the tax bill could more than double from about $280 million during the deferral period to about $750 million after the deferral ends. these tax changes could cause a temporary flood of multifamily properties to hit the market in the first half of 2026.
the financial environment is also not favorable: the lower limit of the risk-weighted loan-to-value ratio for banks has been raised from 15 percent to 20 percent, which will further tighten banks' ability to supply loans. pressure from financial authorities to manage household debt is likely to continue, including the application of a stressed DSR of 3.0 percent and the incorporation of DSR into total household expenditure.
in this environment, experts suggest a 3R strategy reduce unnecessary assets, relocate to promising locations, and rebuild the asset portfolio. in particular, it's wise to proactively manage tax risk by clearing out homes that have met the two-year holding period requirement before May 2026.
7. conclusion and recommendations for future market action
taking the 2025 real estate market outlook and the 2026 real estate outlook together, the market has entered an era where the power of location dominates price. Regulations are becoming more sophisticated and lending thresholds are rising, but a huge tidal wave of supply shortage is hitting the market.
apartments in the core of Seoul have become more than just a place to live, they've become the last bastion of defense for asset values, while the provinces are going through a long tunnel of stagnation, suffering from the double whammy of population decline and oversupply. market participants should closely monitor government policy signals, but base their decisions on supply and demand indicators two to three years out, rather than being swayed by temporary regulatory changes.
now is the time for wisdom, rather than over-extension, to secure prime locations with debt they can afford, or to capitalize on lotto opportunities that are subject to price caps. ensuring your own housing security against the rental shortage and supply shock of 2026 should be a top priority in your wealth management.
frequently Asked Questions (FAQ)
Q 1. Will apartment prices in Seoul continue to rise in 2025?
experts believe that despite high interest rates and lending restrictions, prices will continue to rise due to the lack of supply in core Seoul and the preference for safe assets. however, the rise may slow down somewhat as transaction volume decreases after the October 15 measures.
Q 2. What is your outlook for the charter market in 2026?
very pessimistic. with occupancy volumes plummeting to half of what they used to be, coupled with the echo generation entering the market, we could see an unprecedented charter shortage. this could be the catalyst that pushes sales prices back up.
Q 3. Should I sell my home before May 2026?
if you're a multifamily homeowner, it's absolutely tax advantageous to pay the balance during the transfer tax and before May 9, 2026, when the deferral ends. this is because your tax burden could increase by hundreds of millions if the deferral is not extended.
Q 4. Is now a good time to buy if I'm not a homeowner?
if you can afford it, the capped market should be your first priority. while lending regulations are strong, it can be beneficial in the long run to take advantage of first-time buyer benefits and try to buy a home in Seoul.
Q 5. When will the local apartment market recover?
the provinces are increasingly polarized from the capital, so it is difficult to expect a surge in the short term. however, there is a possibility that the market could begin a gradual recovery from 2026 onwards, driven by new developments in well-located areas.
bottom line: 2025 will be the culmination of the supply-demand imbalance, with regulations holding the market down, but 2026 will be the culmination of the supply-demand imbalance lifting the market.
