SUMMARY
Jeju buy-to-let is selectively profitable now, but only when the property is bought cheaply enough to produce roughly 4% gross yield from legal long-term rent.
The opportunity comes less from booming rents than from weaker purchase prices. Jeju's difficult sales market has shifted bargaining power toward buyers, so the same rental income can now produce a much better yield than it did at peak valuations.
Actual transactions show a meaningful gap between good and mediocre deals. Smaller apartments around KRW 200 million can reach roughly 4% gross, while properties priced at KRW 400 million to KRW 500 million often fall toward 2.5% to 3.5% unless the rent is unusually strong.
Oversupply is still getting worse rather than clearing. Jeju recently reached 3,303 unsold homes, including 2,364 already-completed properties, which keeps pressure on developers and resale sellers and gives income-focused buyers a reason to negotiate aggressively.
The rental side is healthier than the sales side. Recent rental transactions have been running well above both the previous year and the five-year average, showing that people are still taking homes even while fewer households want to buy them.
Jeju's declining population is the main structural warning. The island has lost residents after years of expansion, so properties that need broad population growth to stay occupied look much riskier than compact units in established employment and residential areas.
Tourism helps Jeju's economy, but ordinary apartment investors should not confuse visitor growth with residential rental demand. Airbnb and other short-term accommodation models are regulated, and a normal apartment should make sense financially without assuming tourist income.
Jeju City currently offers the cleaner conventional buy-to-let case. Its larger year-round tenant base, deeper transaction market and concentration of jobs and services make established districts such as Oedo, Yeondong, Nohyeong, Ildo and Ara easier to underwrite than thin resort-oriented locations.
Debt weakens most deals. With average new Korean bank lending around 4.3%, borrowing costs are above the gross yield of many Jeju apartments before vacancy, repairs, taxes and other ownership expenses are deducted.
The practical rule is simple: start with completed leases, not the asking price. A unit reliably renting for KRW 1 million a month is worth about KRW 300 million at a 4% gross yield; once the purchase price climbs far above that, the investment increasingly depends on future appreciation rather than rental income.
The better Jeju buy-to-let opportunities are therefore ordinary rather than glamorous: older or moderately priced apartments, plenty of recent leases, regular resale transactions and obvious year-round tenant demand. The island itself is not an automatic income play, but individual apartments bought at the right price can still work.

Is buy-to-let property profitable in Jeju Island now?
Is Jeju buy-to-let actually profitable now?
Jeju buy-to-let can currently work at around 3% to 4% gross yield, but we would only call the better deals genuinely attractive once they get close to 4%.
Recent Ministry of Land transaction records give us a much better picture than advertised yields. At Oedo Buyoung 1 in Jeju City, 49.9 m² apartments have recently traded around KRW 200 million, while leases on the same size have repeatedly closed around KRW 630,000 to KRW 700,000 per month with small deposits. Using KRW 200 million as the purchase price, that works out at roughly 3.8% to 4.2% gross before expenses.
Other complexes come out lower. An 84.95 m² apartment bought for KRW 360 million and rented for around KRW 900,000 to KRW 1 million per month produces roughly 3% to 3.3%. Paying KRW 400 million for a unit renting at KRW 1.25 million gives about 3.75%.
So the market does contain properties that produce decent rent. The problem is that 3% to 4% gross leaves limited room for financing, vacancy, maintenance and buying costs. Jeju works much better today for a cash buyer who negotiates hard than for someone stretching to buy a new apartment with debt.
| Example economics | Purchase price | Monthly rent | Approx. gross yield | Our view |
|---|---|---|---|---|
| Oedo Buyoung 1, 49.9 m² | ~KRW 200m | KRW 630k-700k | ~3.8%-4.2% | Interesting |
| 84.95 m² older apartment example | ~KRW 360m | KRW 900k-1m | ~3.0%-3.3% | Acceptable, price-sensitive |
| Central Jeju City example | ~KRW 400m | ~KRW 1.25m | ~3.75% | Reasonable |
| KRW 500m unit at KRW 1m rent | KRW 500m | KRW 1m | 2.4% | Too weak for us |
Why does Jeju buy-to-let look more interesting today than a few years ago?
Jeju rental property looks more interesting now mainly because buyers have regained bargaining power while rents in established areas have held up better than sale prices.
Jeju spent much of the previous decade riding unusually strong housing demand. The island attracted domestic migrants, tourism investment and foreign capital, while expectations around infrastructure and development pushed land and apartment values much higher.
That cycle has changed. Population growth has reversed, speculative demand has faded and developers are struggling to clear housing they have already completed.
For landlords, lower purchase prices can improve the calculation very quickly. A property producing KRW 12 million a year gives only 2.4% gross yield at KRW 500 million. At KRW 350 million, the same rent gives 3.4%. At KRW 300 million, it reaches 4%.
This is why Jeju buy-to-let interests us more these days than it did during the boom. Rental income has not suddenly become spectacular. Entry prices are simply less forgiving for sellers and more useful for landlords.
Don't buy the wrong property, in the wrong area of Jeju Island
Buying real estate is a significant investment. Don't rely solely on your intuition. Gather the right information to make the best decision.
Is Jeju's housing oversupply getting better?
No. Jeju's housing oversupply has actually become worse lately, and the latest figures are strong enough to change how we would approach any purchase.
Ministry of Land housing statistics showed 3,303 unsold homes across Jeju at the end of July, up 13.5% in a single month from 2,909. It was the first time the island had crossed 3,000 unsold homes.
More concerning, 2,364 of those properties were already completed and still unsold, another record. Roughly 72% of Jeju's unsold stock was therefore finished housing looking for buyers.
The deterioration is striking because the province had only 2,700 unsold homes a few months earlier. Jeju had already launched a public-private housing programme offering combinations of developer discounts, delayed final payments, appliances and tax support to help clear completed inventory. Despite those efforts, the unsold total subsequently climbed above 3,300.
Location matters here. Jeju City's latest unsold stock was about 2,299 homes, while Seogwipo accounted for around 1,004. Individual neighbourhoods can still perform well, but buyers should assume that developers and resale sellers will remain under pressure in weaker projects.
For a landlord, that pressure can create opportunities. We would simply refuse to pay a price based on the previous cycle when thousands of completed or nearly completed homes are still competing for buyers.
| Jeju unsold housing | Earlier reading | Latest reading | Change |
|---|---|---|---|
| Total unsold homes | 2,700 | 3,303 | +603 |
| Completed unsold homes | 2,201 | 2,364 | +163 |
| Share already completed | ~82% at earlier reading | ~72% now | Still exceptionally high |
| Jeju City unsold homes | — | 2,299 | Largest concentration |
| Seogwipo unsold homes | — | 1,004 | Smaller but still substantial |
Are Jeju rents holding up better than property sales?
Yes. Jeju's rental market currently looks healthier than its sales market, which is one of the strongest points in favour of selective buy-to-let.
Ministry of Land data showed 2,687 Jeju rental transactions in one recent month. That was 28.1% higher than a year earlier and 38.4% above the five-year average for the same month. Housing sales, by comparison, were still 8.9% below their five-year average despite improving year-on-year.
People still need housing even when fewer of them want to buy it.
Actual leasing records in Oedo show the same pattern at building level. Oedo Buyoung 1 recorded dozens of monthly-rent contracts over the past year. Its 49.9 m² units regularly appeared around KRW 630,000 to KRW 700,000 per month, while 59.9 m² units could reach the KRW 700,000-KRW 900,000 range depending on deposit and floor.
So we do have evidence of recurring tenant demand rather than a handful of optimistic listings. The opportunity is strongest where sale prices have weakened without pulling monthly rents down by the same amount.

Is Jeju's shrinking population becoming a serious problem for landlords?
Yes. Jeju's shrinking population is now a real buy-to-let risk, especially for properties that depend on broad island-wide housing demand rather than a strong local neighbourhood.
Jeju Province's latest population dashboard puts the combined domestic and registered-foreign population at about 691,100. The province lost 5,058 residents during the previous year, a decline of 0.7%, and domestic migration was still slightly negative in the latest available monthly reading.
That is a major change from Jeju's previous story. The island spent years gaining residents and eventually moved above 700,000 people. A landlord who bought during that period benefited from an expanding pool of households chasing housing. We cannot assume that tailwind anymore.
There is one useful countertrend. Jeju had 96,391 one-person households in the latest full-year data. Smaller households can keep demand for compact rentals relatively firm even when the total number of residents falls.
We see much more risk in a large apartment or remote development that needs continuous population growth than in a modest unit close to employment, transport and everyday services.
| Jeju demographic indicator | Latest reading | Direction | Buy-to-let effect |
|---|---|---|---|
| Total population incl. registered foreigners | ~691,100 | Falling | Negative |
| Previous annual population change | -5,058 | Falling | Negative |
| Population growth rate | -0.7% | Negative | Negative |
| One-person households | 96,391 | High / long-term growth | Supports smaller rentals |
| Latest domestic migration balance | -33 | Slightly negative | Weak |
Does Jeju tourism make residential buy-to-let more profitable?
Jeju's tourism recovery helps the island economy, but it does far less for an ordinary apartment landlord than the visitor numbers initially suggest.
Jeju received about 6.77 million tourists during the first half of the latest reported year, 6.7% more than during the same period a year earlier. Domestic visitors rose 4.4% to roughly 5.56 million, while foreign arrivals jumped 18.6% to about 1.20 million.
Those are substantial numbers for an island with fewer than 700,000 residents.
But tourists and long-term apartment tenants are different customers. Someone renting a normal apartment in Oedo, Ildo or Ara generally cares about work, schools, commuting, shops and everyday life. Another million tourists do not automatically lift that person's monthly rent.
Tourism adds some economic support through employment and spending, while the direct rental opportunity belongs mainly to legally operated accommodation businesses.
Buying real estate in Jeju Island can be risky
An increasing number of foreign investors are showing interest. However, 90% of them will make mistakes. Avoid the pitfalls with our comprehensive guide.
Can a Jeju investor just put a normal apartment on Airbnb?
No. A Jeju investor should never underwrite a normal residential apartment assuming unrestricted Airbnb income.
South Korea regulates accommodation businesses by category, and the rules depend on the type of property, location, operator and guest.
An urban foreign-tourist homestay can operate from certain residential properties, including apartments, but it comes with conditions and is designed around accommodation for foreign tourists. The operator generally needs to live in the property. That clearly differs from buying several apartments as passive short-term rentals.
Rural homestay businesses operate under another regime, with residence, registration and property requirements. These are closer to running an accommodation business than simply becoming a landlord.
Airbnb has also tightened enforcement in Korea by requiring hosts to provide valid accommodation-registration information. Listings that cannot demonstrate legal eligibility face restrictions on taking reservations.
For our calculations, we would therefore value an ordinary Jeju apartment from its legal long-term rent. Any verified short-term accommodation rights would be treated separately.
| Rental strategy | Can investors assume it? | Main issue |
|---|---|---|
| Standard long-term rental | Yes | Normal tenancy economics |
| Urban foreign-tourist homestay | Only if eligible | Operator/residence and guest restrictions |
| Rural homestay | Only if eligible | Property, residence and registration rules |
| Unlicensed Airbnb | No | Licensing requirements |
| Licensed tourist accommodation | Yes, if properly authorised | Different business model from ordinary buy-to-let |
Is Jeju City safer for buy-to-let than Seogwipo right now?
Yes. Jeju City is currently the safer place for conventional buy-to-let because the year-round tenant pool is much larger and the resale market is deeper.
Most of the island's residents, jobs, government functions and everyday commercial activity are concentrated in Jeju City. That gives landlords several sources of rental demand rather than depending heavily on tourism or one local employer.
Seogwipo can still work, but the rental market is more fragmented. Jungmun has tourism-related employment, Gangjeong has its own local demand and the innovation-city area has public-sector workers, yet a property several kilometres away can behave very differently.
The latest housing inventory gives us another reason to stay selective. As seen above, Jeju now has more than 3,300 unsold homes, including about 1,000 in Seogwipo. In a smaller tenant and resale market, excess stock can be harder to absorb.
We would accept a slightly lower yield in a proven Jeju City neighbourhood than in a thin Seogwipo location. A Seogwipo purchase should usually compensate us with a lower price or better rent.

Which Jeju City areas make the most sense for rental property?
Established middle-market parts of Jeju City currently look more convincing for buy-to-let than prestigious new developments.
Oedo is one of the clearest examples because transaction volume gives us enough evidence to test the numbers. Oedo Buyoung 1 has more than 1,000 apartments, and recent Ministry of Land records show repeated sales, jeonse leases and monthly-rent contracts. The 49.9 m² units around KRW 200 million are particularly interesting when monthly rent stays around KRW 630,000 to KRW 700,000.
Yeondong and Nohyeong have stronger central locations, good retail and easy access to the airport, but investors can easily overpay there. A good neighbourhood does not save a rental deal when a new apartment costs twice as much as an older one but earns only moderately more rent.
Ildo can offer a better purchase-price-to-rent relationship in older complexes, while Ara remains popular with residents but often carries a higher acquisition price.
The pattern we would look for today is a fairly ordinary apartment in a proven residential district, enough transactions to establish a real market price, and rent that gives close to 4% gross. Paying a large premium for a newer building usually pushes the yield in the wrong direction.
Is jeonse useful for a Jeju buy-to-let investor?
Yes, but jeonse changes the financing of a Jeju property more than it improves the rental income.
Under a jeonse lease, the tenant provides a large refundable deposit instead of paying substantial monthly rent. For an owner, that deposit can dramatically reduce the amount of personal capital tied up in the property.
Oedo Buyoung 1 gives a current example. Recent 20-pyeong transactions put sale prices around KRW 200 million, while jeonse contracts have closed around KRW 140 million to KRW 165 million. A landlord buying for KRW 200 million and taking a KRW 160 million jeonse deposit has only KRW 40 million of net capital left in the property while the lease is running.
That can be powerful, but the KRW 160 million still belongs to the tenant and must eventually be returned. The landlord also receives little or no monthly rental cash flow.
Jeonse therefore makes much more sense when the investor wants cheap capital and expects the property itself to hold or increase its value. For readers asking whether Jeju can produce useful recurring income, monthly-rent contracts remain the cleaner test.

Does borrowing money make Jeju buy-to-let unattractive now?
Yes, in most cases. Current Korean borrowing costs are too high relative to ordinary Jeju apartment yields for leverage to improve the deal.
The Bank of Korea recently raised its policy rate to 3.00%. Its latest published banking figures put the average rate on new loans at 4.31%, while new deposits averaged 3.08%.
Compare 4.31% borrowing with a Jeju apartment producing 3.5% gross rent. The property's entire rent already yields less than the average cost of new borrowing, even before maintenance, vacancy, taxes or brokerage.
A stronger apartment at 4.2% gross gets much closer, but the spread is still uncomfortable.
Cash buyers face a different comparison. A bank deposit around 3.1% requires almost no property management and has none of the resale risk of an apartment. We would want a meaningful premium over that return before accepting the extra work and illiquidity of residential property.
| Current return or rate | Approximate level | What it means |
|---|---|---|
| Strong Jeju apartment gross yield | ~4.0%-4.2% | Potentially interesting |
| Ordinary Jeju gross yield | ~3%-4% | Thin after costs |
| New bank deposit rate | ~3.08% | Strong competitor for cash |
| New bank loan rate | ~4.31% | Above many rental yields |
| Bank of Korea base rate | 3.00% | Financing has recently tightened |
How much do taxes and other costs reduce Jeju rental yields?
Enough that we would treat a 3% gross yield as weak rather than genuinely profitable.
Many lower-priced Jeju apartments fall into Korea's lower standard acquisition-tax bands, although the exact tax depends on value, ownership status and the type of property. Buyers also face brokerage, registration expenses and eventual selling costs.
Then come the recurring expenses. Even a fairly simple apartment can have periods without a tenant, repairs, maintenance charges that cannot be passed through, insurance and taxes.
Take a KRW 300 million apartment collecting KRW 900,000 per month. Annual rent is KRW 10.8 million, or 3.6% gross. Lose KRW 1.5 million to KRW 2 million across vacancy and owner expenses and the return falls to roughly 2.9%-3.1% before considering purchase and eventual resale costs.
At 4.2% gross, those same expenses leave a more usable margin.
That difference between 3% and 4% may look small on paper, but for Jeju buy-to-let it can separate a property that basically needs appreciation from one that can justify itself through rent.

What price should a Jeju landlord actually be willing to pay?
We would work backward from the real rent and target at least about 4% gross, because today's Jeju market gives buyers enough leverage to be demanding.
If a realistic monthly rent is KRW 1 million, annual rent is KRW 12 million. A 4% target implies a maximum purchase price of roughly KRW 300 million.
At KRW 350 million, the yield drops to about 3.43%. At KRW 400 million it becomes 3%. At KRW 500 million it falls to only 2.4%.
The same approach works for smaller apartments. A property reliably earning KRW 700,000 per month produces KRW 8.4 million annually. To reach 4% gross, we would want to pay around KRW 210 million or less.
This is particularly useful now because Jeju has record unsold inventory and sellers cannot rely on the same demand conditions they enjoyed during the previous boom.
The advertised price should be almost irrelevant to an income investor. Start with completed leases in the building, calculate what tenants genuinely pay, set the yield required, and let that determine the maximum offer.
| Real monthly rent | Annual rent | Price at 3% yield | Price at 4% yield | Price at 5% yield |
|---|---|---|---|---|
| KRW 600k | KRW 7.2m | KRW 240m | KRW 180m | KRW 144m |
| KRW 700k | KRW 8.4m | KRW 280m | KRW 210m | KRW 168m |
| KRW 1m | KRW 12m | KRW 400m | KRW 300m | KRW 240m |
| KRW 1.25m | KRW 15m | KRW 500m | KRW 375m | KRW 300m |
What would make us buy a Jeju rental property today?
A Jeju rental property becomes interesting to us today when the gross yield reaches roughly 4%, several recent leases prove the rent, and the property sits in a place with obvious year-round tenant demand.
We would rather buy an older apartment with 20 recent rental contracts than a beautiful new development where the agent has to tell us what the rent "should" be.
Liquidity matters too. A complex with regular sales gives us a believable entry price and a realistic way out later. That is one reason large established complexes in Jeju City can make more sense than distinctive villas or remote resort properties.
Debt would ideally be low. With average new borrowing around 4.3%, using large amounts of leverage against a 3%-4% gross-yield apartment makes little sense.
And we would never use hoped-for Airbnb revenue to rescue a weak deal. The standard residential rent should already make the purchase acceptable.
Those conditions narrow the market quite a lot. That's fine. Jeju currently rewards patient buyers more than people who simply want exposure to the island.

So, is buy-to-let property profitable in Jeju Island now?
Yes, selectively. Jeju buy-to-let can be profitable now, but we would target roughly 4% gross yield and reject most properties that only produce 2% to 3%.
Several things have improved for new buyers. Sale prices are negotiable, established Jeju City apartments still record healthy monthly-rental activity, and rental transactions have recently been running well above their five-year average.
The risks have also become harder to ignore. Jeju's population is declining, unsold housing has just reached a record 3,303 units, 2,364 completed homes are still waiting for buyers, and Korean loan rates around 4.3% sit above the gross yield of many apartments. Tourism is performing well, with visitor numbers up 6.7% in the latest first-half figures, but ordinary residential landlords cannot freely turn that demand into Airbnb income.
We would focus on older or moderately priced apartments in established Jeju City neighbourhoods, verify the rent from actual signed contracts and work backward to a maximum purchase price. Oedo-type deals around KRW 200 million with rent around KRW 630,000-KRW 700,000 are much closer to what we want than expensive new apartments offering only a small rental premium.
Jeju has become a better buy-to-let market for disciplined buyers precisely because its property market has become more difficult. The island as a whole is not a strong income bet. The right apartment bought cheaply enough can be.
OUR METHODOLOGY
We assessed Jeju buy-to-let by breaking the investment case into the factors that directly affect a landlord's return: achievable rent, actual purchase prices, transaction depth, housing supply, tenant demand, demographics, financing costs, operating expenses, regulation and location.
At property level, we prioritized completed transactions over asking prices. South Korea's Ministry of Land, Infrastructure and Transport Real Transaction Price Disclosure System was used to compare actual apartment sales with signed jeonse and monthly-rent contracts, including the Oedo Buyoung examples used to reconstruct gross yields.
For the wider housing market, we used Ministry of Land housing statistics and its statistical system to assess sales and rental activity, total unsold housing and completed unsold stock. This is also the basis for the comparison between Jeju City and Seogwipo inventory pressure.
Demographic assumptions come from Jeju Special Self-Governing Province's population data, including total population, recent population decline, migration and one-person households. Tourism figures come from the Jeju Tourism Organization's Tourism Big Data Platform, which we treated as economic context rather than as a proxy for ordinary residential rental demand.
Financing comparisons use Bank of Korea data. We compared gross property yields with the policy rate, average rates on new bank loans and average rates on new deposits so that leverage and the opportunity cost of holding cash could be judged against current conditions rather than historical borrowing assumptions.
For short-term rentals and acquisition costs, we used Korean legal and regulatory sources rather than assuming that a normal residential apartment can operate freely as tourist accommodation. Relevant sources include the National Law Information Center for the Local Tax Act, the Tourism Promotion Act framework and rural-homestay requirements, alongside Airbnb's own Korean host-compliance guidance.
We did not let any single indicator determine the conclusion. Tourism growth can coexist with weak residential investment economics, falling population can coexist with strong rental demand in a specific neighbourhood, and record unsold inventory can create both risk and better entry prices. We therefore compared those factors together and then worked backward from realistic rent to the maximum purchase price that would support the target yield.
Key sources include the Ministry of Land, Infrastructure and Transport Real Transaction Price Disclosure System, MOLIT's July 2026 housing statistics, MOLIT's unsold-housing statistics, Jeju Province's population dashboard, the Jeju Tourism Organization Tourism Big Data Platform, the Bank of Korea's August 2026 monetary-policy decision, Bank of Korea lending and deposit-rate data, the Local Tax Act, the Tourism Promotion Act framework for urban foreign-tourist homestays, official guidance on rural homestay requirements, Airbnb's Korean regulations and permissions guidance, and the Korea Real Estate Board's national housing-price trends.
