Is owning a second home in Korea still worth it?

Get all the data you need about the real estate market in Seoul

Why has owning a second home in Seoul become much harder?

Owning a second home in Seoul is currently much harder to justify because Korea has tightened the rules at almost every stage of the investment, from buying and borrowing to holding and eventually selling.

Seoul was brought fully back under regulated-area rules in late 2025. Under Seoul Metropolitan Government tax guidance, a household buying a second home in a regulated area can face an 8% acquisition-tax rate, compared with the ordinary 1% to 3% housing rate. Existing homeowners also have effectively no standard purchase mortgage available for another home in the Seoul metropolitan area unless the transaction is really a replacement-home purchase.

The squeeze continued this year. The Financial Services Commission began restricting mortgage maturity extensions for multi-home owners holding apartments in Seoul and other regulated areas, with exceptions for situations such as an existing tenant preventing an immediate sale. The temporary relief from Korea's heavier capital-gains tax for multi-home owners also ended after nearly four years.

Put together, the rules have changed the basic economics of a second Seoul apartment. The property can still rise sharply in value, but an investor now needs considerably more appreciation to overcome the cost of getting in, the lack of leverage and the tax risk when getting out.

Rule	Ordinary one-home situation	Second home in regulated Seoul	Effect on the buyer
Acquisition tax	Generally 1% to 3%	8%	Much larger upfront cost
Purchase mortgage	Available within lending limits	Generally unavailable to an existing homeowner buying another capital-area home	Requires much more cash
Capital-gains surcharge	Normal CGT rules	Base rate +20 percentage points for qualifying two-home households	Makes selling more expensive
Long-term holding deduction	Can be available	Generally lost when the multi-home surcharge applies	Reduces benefit of a long hold
Mortgage maturity extension	Normal underwriting	Now restricted for multi-home owners in affected apartments	Adds refinancing pressure

Are Seoul apartment prices still rising enough to make a second home tempting?

Yes. Seoul apartment prices are still rising quickly today, so the case against a second home cannot be based on a weak housing market.

KB Real Estate's latest nationwide housing survey showed Seoul apartment prices rising 1.14% in one month. The average Seoul apartment reached about ₩1.607 billion, while the citywide median was roughly ₩1.292 billion.

The more interesting part is where the increases are happening. Jungnang rose 2.25% in the month, Seongbuk 2.08%, Nowon 1.95%, Jongno 1.94%, Gangseo 1.86% and Guro 1.81%. Several northern and outer Seoul districts are now running ahead of the city's traditional premium areas.

Jungnang had already led Seoul price growth the previous month, so this is more than a one-week spike in a single district. The rise has broadened into parts of Seoul where absolute prices remain lower and buyers may still see room for the gap with central areas to narrow.

That does help the second-home case. A buyer does not necessarily have to pay Gangnam prices to participate in Seoul's current appreciation. But cheaper northern Seoul does not remove the 8% acquisition-tax rate or the mortgage restrictions, because those rules depend mainly on the household's ownership position and the regulatory area.

Seoul apartment measure	Latest reading	What stands out
Monthly price growth	+1.14%	Momentum remains strong
Average apartment price	≈₩1.607bn	Entry cost is already very high
Median apartment price	≈₩1.292bn	High prices extend well beyond luxury stock
Jungnang monthly growth	+2.25%	Strongest district for a second straight month
Seongbuk monthly growth	+2.08%	Northern Seoul remains very strong
Nowon monthly growth	+1.95%	Lower-priced outer districts are repricing too

Is Seoul actually running short of apartments right now?

Yes. Seoul has a real near-term apartment shortage, and the latest completion numbers are severe enough to help explain why prices and rents remain so firm.

According to the Ministry of Land, Infrastructure and Transport's latest housing statistics, only 17,603 Seoul apartments were completed during the first seven months of the year. That was 48.7% fewer than the 34,339 completed over the same period a year earlier.

Total housing completions in Seoul, including non-apartments, fell 43.3%. That is a major drop for a city where households already compete over a limited stock of apartments in desirable districts.

There is one important counterweight further up the pipeline. Seoul apartment starts rose 36.1% year on year to 14,995 units over the same seven-month period, while total housing starts rose 44.4%. July alone recorded 5,574 apartment starts, around twenty times the level of July a year earlier.

So today's shortage is real, but construction is finally moving in the other direction. The strongest supply argument is a near-term one. Buying a second home on the assumption that Seoul will face an ever-worsening shortage for another decade goes beyond what the current data supports.

Are people still buying Seoul apartments, or are prices rising on very few deals?

Seoul apartment demand is weaker than the price charts make it look because transactions are currently falling even as prices keep climbing.

The Ministry of Land recorded 6,564 Seoul apartment transactions in July. That was 15.2% below the previous month and 22.6% below the same month a year earlier.

It is a strange-looking market. Available homes remain scarce enough for completed transactions to clear at higher prices, while tighter credit and high absolute prices keep many potential buyers out. Owners also have little reason to sell cheaply when rental conditions are strong and new supply is limited.

For a long-term homeowner, lower transaction volume is manageable. A second-home investor has more reason to care because Seoul already comes with high entry and exit friction. A market where prices rise but fewer homes trade gives an owner less freedom over the timing of a future sale.

Scarcity still looks bullish. Liquidity does not.

Does Seoul's 8% acquisition tax wipe out too much of the return?

For many second-home buyers, yes. Seoul's 8% acquisition tax can consume the equivalent of several years of rental income before the investment has even started.

Seoul Metropolitan Government's current guidance puts the ordinary housing acquisition-tax rate at 1% to 3% depending on the purchase price. A second home in a regulated area is generally taxed at 8%, subject to exceptions such as certain temporary two-home situations.

At today's roughly ₩1.292 billion Seoul median apartment price, 8% equals about ₩103 million. At the current average of around ₩1.607 billion, it reaches roughly ₩129 million.

Compare that with the normal 3% rate applying to an expensive single-home purchase. On a ₩1.607 billion apartment, 3% is about ₩48 million. The difference is around ₩80 million before associated local surtaxes and transaction expenses.

If the apartment rises 5%, the paper gain is also close to ₩80 million. Roughly the first 5% of appreciation can therefore disappear in the extra acquisition tax created by second-home status. That's a brutal starting line.

Purchase price	3% acquisition tax	8% second-home tax	Extra tax
₩800m	₩24m	₩64m	₩40m
₩1.0bn	₩30m	₩80m	₩50m
₩1.292bn	≈₩38.8m	≈₩103.4m	≈₩64.6m
₩1.607bn	≈₩48.2m	≈₩128.6m	≈₩80.4m
₩2.0bn	₩60m	₩160m	₩100m

Can you still get a mortgage for a second home in Seoul?

Usually no. An existing homeowner trying to buy another Seoul property can currently expect to fund almost all of the purchase with cash.

Capital-region mortgage rules set the purchase LTV at effectively 0% for households already owning a home when they buy an additional property, unless they are disposing of the first home and genuinely replacing it.

That changes the return dramatically. Imagine a ₩1.5 billion apartment appreciating by 5%. The owner makes a ₩75 million paper gain. With heavy leverage, that could produce a strong return on the cash invested. With ₩1.5 billion of equity tied up in the apartment, the same ₩75 million represents only 5% before taxes, expenses and inflation.

The government tightened multi-home financing again this year. Financial Services Commission rules now generally prevent maturity extensions on mortgages secured by apartments owned by multi-home borrowers in the Seoul metropolitan area and regulated zones. Existing tenant situations and a few other unavoidable cases can qualify for exceptions.

The policy is aimed directly at reducing leveraged multi-home ownership. A second Seoul apartment today is mainly a product for cash-rich buyers, which makes the opportunity cost of the money much harder to ignore.

Can you buy a second Seoul apartment and immediately rent it out?

Sometimes, but land transaction permit rules can block exactly that strategy for properties covered by the system.

For qualifying homes inside Seoul land transaction permit zones, residential purchases can carry a real-residence requirement. Government guidance has generally required the buyer to move into the property within the permitted period and use it as a residence for two years.

That creates an obvious problem for someone who wants a conventional investment property. Buying an apartment, putting a tenant in immediately and collecting rent may simply be incompatible with the permit attached to the transaction.

The issue is especially relevant because highly sought-after areas and redevelopment locations are often among the places most likely to face tighter controls. Seoul has repeatedly expanded or adjusted these zones when speculative demand accelerates.

A buyer therefore has to check the specific apartment and permit status before assuming rental income will be available from day one. In Seoul these days, the regulatory details of one building can change the economics of an otherwise attractive purchase.

Are Seoul rents rising enough to save the second-home investment?

No, not on their own. Seoul rents are rising fast, but ordinary apartments still struggle to generate enough income relative to their enormous purchase prices.

The rental pressure is clear. Korea Real Estate Board data showed average Seoul apartment monthly rent rising from about ₩1.343 million at the beginning of 2025 to ₩1.476 million by the end of that year. KB's apartment monthly-rent index hit its highest level since the series began.

The latest Ministry of Land data shows the market moving even further toward monthly rent. During the first seven months of this year, 69.7% of all Seoul lease transactions across housing types involved monthly rent rather than pure jeonse. Jeonse transactions have been falling faster than monthly-rent deals nationally as tighter borrowing conditions make large deposits harder to finance.

The problem is the purchase price. Even ₩30 million of annual gross rent on a ₩1.5 billion apartment produces only a 2% gross yield. ₩45 million produces 3%.

Those yields leave little room for tax, vacancy, repairs, building fees and the very large acquisition cost. Rising rent helps, but a Seoul apartment investor is still relying heavily on capital gains.

Does rental-income tax make a second home noticeably worse?

Yes, although it is not the biggest problem. Korea taxes rental income more aggressively once a household owns multiple homes, which chips away further at already modest Seoul apartment yields.

The National Tax Service states that a household with two homes is generally taxed on monthly housing rental income. If annual housing-rental revenue is no more than ₩20 million, the owner can generally choose separate taxation at 14% or comprehensive taxation. Above ₩20 million, the income normally joins other comprehensive taxable income, where Korea's progressive rates run much higher.

The rules have also widened for some high-value deposit-based rentals. Certain two-home households with expensive properties can now face deemed-rental-income taxation when large deposits cross the relevant thresholds.

This rarely decides the investment on its own. The acquisition tax, lack of leverage and eventual selling tax are much bigger. But when the gross yield is only in the low single digits, even a relatively small extra tax drag is noticeable.

Has selling a second home in Seoul become much more expensive again?

Yes. The return of Korea's heavier capital-gains tax on multi-home owners has made the exit side of a second Seoul home considerably harsher.

The temporary suspension of the surcharge ended this year after running for almost four years. In designated speculative areas, an owner selling while classified as a two-home household can face another 20 percentage points on top of the ordinary capital-gains rate. Households with three or more homes can face another 30 points.

Korea's ordinary real-estate capital-gains rates already rise to 45%. Government statements around the end of the exemption noted that the maximum national rate for affected multi-home sales could reach about 75% before local surtax.

Properties hit by the multi-home surcharge also generally lose the long-term holding special deduction.

The buyer has already paid heavily to enter the investment. A punishing exit tax raises the appreciation hurdle again, which is why the eventual sale needs to be thought through before the purchase, not five years later.

Selling position	General tax treatment
Ordinary taxable home sale	Normal progressive CGT
Two-home household selling qualifying regulated-area home	Normal rate +20 percentage points
Three-home household or more	Normal rate +30 percentage points
Sale subject to multi-home surcharge	Long-term holding special deduction generally unavailable
Potential top national rate	About 75% before local surtax

Can a second Seoul apartment still beat cash, bonds or stocks?

It can, but Seoul property currently needs substantial capital appreciation to compensate for the amount of cash trapped in the investment.

Take a ₩1.5 billion apartment bought without a mortgage. At a 2% gross yield, annual rent is ₩30 million. At 3%, it is ₩45 million. The 8% acquisition tax alone is ₩120 million.

At a 2% gross yield, four years of gross rent merely equals the acquisition tax. At 3%, it takes about 2.7 years. Those calculations come before maintenance, vacancies, rental-income tax, selling costs and capital-gains tax.

Now add appreciation. If a ₩1.5 billion apartment compounds at 5% annually for five years, its value rises by about ₩414 million. That is enough to make the investment interesting even after a painful entry cost, although the eventual tax position still matters enormously.

At 2% annual appreciation, the five-year capital gain is only about ₩156 million. Suddenly the ₩120 million acquisition tax consumes most of the property gain before any of the other costs are included.

This is why a second Seoul apartment is unusually sensitive to house-price growth. Moderate appreciation turns into mediocre economics very quickly.

Five-year annual price growth	Approx. value after 5 years on ₩1.5bn	Approx. capital gain	Acquisition tax as % of gain
0%	₩1.500bn	₩0	No capital gain
2%	≈₩1.656bn	≈₩156m	≈77%
3%	≈₩1.739bn	≈₩239m	≈50%
5%	≈₩1.914bn	≈₩414m	≈29%
7%	≈₩2.104bn	≈₩604m	≈20%

Is 5% annual Seoul apartment appreciation a realistic assumption?

A few strong years are entirely possible, but assuming 5% every year for a long holding period is too aggressive for a second-home investment case.

Today's housing data gives bulls plenty to work with. Seoul apartment completions through July were down 48.7% year on year, rents remain under pressure, and KB's latest survey still shows prices rising at more than 1% in a single month.

Demand also remains unusually concentrated in Seoul despite South Korea's shrinking national population. Jobs, universities, schools and high-value services continue to pull households toward the capital, while redevelopment and reconstruction take years to produce new apartments.

Affordability still puts a ceiling on how long extreme appreciation can run. The average Seoul apartment already costs around ₩1.6 billion. Another doubling would move the ordinary apartment market even further beyond the financing capacity of most wage-earning households.

Policy is the other ceiling. Korea has repeatedly responded to rapid Seoul price gains with lending restrictions, tax changes and permit controls. Those interventions can slow transactions very quickly even when the underlying supply shortage remains.

Firm Seoul prices are easy to defend from today's evidence. A model that quietly assumes 5% or 7% appreciation every year for the next decade is much harder to defend.

Would a Seoul officetel make more sense than a second apartment?

For someone mainly chasing rental income, a Seoul officetel can currently look much better than a second apartment because yields are far higher.

Korea Real Estate Board figures reported this year put the average Seoul officetel sale price around ₩281 million and the average monthly rent around ₩949,000. The reported rental yield was roughly 5.1%.

That is a completely different income profile from a typical Seoul apartment yielding in the low single digits. A 5% rental return gives the owner meaningful cash flow even if property prices grow slowly.

Officetels can also work well around subway stations, employment hubs and universities where one-person households create steady tenant demand. Recent Korea Real Estate Board data has continued to show upward pressure on Seoul officetel rents.

The trade-off is weaker capital appreciation and more complicated classification. A residentially used officetel can count as housing for some tax purposes, while maintenance fees can be high and small-unit tenant turnover is usually greater.

For a pure income investor, though, the yield gap is large enough that an officetel deserves a serious look before paying more than ₩1 billion for an ordinary second apartment.

Who can still make a second home in Seoul work?

A second home in Seoul can still work for a cash-rich buyer with a long holding period, a very good property and a reason to own it beyond collecting rent.

Personal use changes the calculation substantially. Someone buying a future home for retirement, children, work or family gets value from the apartment even while the financial return is mediocre. A stock portfolio cannot provide that option.

Property selection matters just as much. An underpriced unit near a major transport project, a strong school district, a credible redevelopment site or a scarce family-sized apartment can outperform the Seoul average enough to absorb part of the tax burden. The strong price rises now appearing in Jungnang, Seongbuk and Nowon also show that buyers do not have to confine themselves to Gangnam to find momentum.

The holding period needs to be long. On a ₩1.5 billion purchase, an 8% acquisition tax is ₩120 million. If the property appreciates only 10% in total, that tax equals 80% of the ₩150 million paper gain. At 40% total appreciation, it falls to 20% of the gain.

A casual investor hoping to rent an apartment for three or four years and flip it at a profit is playing a bad hand under today's rules. A buyer who can hold a genuinely scarce property for ten years or longer has a much stronger case.

Is owning a second home in Korea still worth it?

For a pure investment, usually no. A carefully chosen second home in Seoul can still work, but the current rules demand unusually strong appreciation and a long holding period before the numbers become attractive.

The housing market itself remains healthy. KB's latest data has Seoul apartment prices rising 1.14% in a month, with the strength spreading into northern and outer districts. The Ministry of Land's newest housing figures show apartment completions down almost half from a year earlier. Rents are high, monthly-rent contracts are taking a larger share of the leasing market, and Seoul still has a real shortage of finished apartments.

The investment structure is much less attractive. Second-home buyers in regulated Seoul can face an 8% acquisition tax, little or no conventional purchase leverage, rental restrictions on some properties and a 20-percentage-point capital-gains surcharge when the relevant multi-home rules apply. Mortgage refinancing has also become more difficult for multi-home owners.

Current Seoul apartment yields are too low to carry those costs by themselves. The buyer therefore needs substantial capital appreciation.

That can happen. Seoul remains one of the strongest housing markets in Korea, and the latest supply numbers still support higher prices. But if appreciation settles around 2% or 3% a year, the combination of acquisition tax, low yield and exit tax can swallow a large part of the return.

For someone seeking rental income, leverage and the flexibility to sell within a few years, a second Seoul apartment is hard to justify today. For someone with enough cash to buy a scarce property, hold it for a decade or more and possibly use it personally later, owning a second home in Seoul can still be worth it.

The opportunity has become much narrower. Seoul housing can keep rising while a second Seoul home remains a poor investment for most buyers.
