SUMMARY

We analyzed apartment rental yields in Seoul, as of 2026, for residential apartment buyers, using the raw Seoul dataset provided and turning it into a practical buyer guide for foreign individual investors.

The dataset compares residential apartments across Seoul neighborhoods and shows estimated purchase prices, monthly rents, gross rental yields, and net rental yields for studios, 1-bedroom apartments, and 2-bedroom apartments.

We update this type of apartment rental yield research regularly, so the numbers should be read as a May 2026 Seoul apartment yield snapshot rather than a permanent market forecast.

The main finding is that Seoul is a low-yield, high-price apartment market. The strongest net yields in the table are mostly around 2.7% to 3.0%, while the weakest prestige areas fall near 1.5% to 2.0% net.

Sinchon / Ewha has the strongest studio yield in the dataset, with a modeled studio price of ₩300m, monthly rent of ₩1.10m, 4.4% gross yield, and 2.9% net yield.

Hannam looks strong on paper, with 2-bedroom apartments reaching about 3.0% net yield, but the interpretation requires caution because older stock, luxury buildings, villas, and international-resident demand sit close together.

Mapo / Gongdeok is one of the cleanest Seoul income markets because studios, 1-bedroom apartments, and 2-bedroom apartments all cluster around 2.7% net yield. That balance suggests broad tenant demand rather than one narrow renter group.

Gangnam Station / Yeoksam is the clearest work-driven compact-apartment market. Studios are modeled at ₩500m and ₩1.50m monthly rent, equal to 3.6% gross yield and 2.5% net yield.

The weakest income profile is in Apgujeong. A 1-bedroom apartment costs about ₩1.55bn and rents for about ₩2.85m per month, leaving only 2.2% gross yield and 1.5% net yield.

For a beginner foreign buyer, the best Seoul apartment rental yield strategy is usually to focus on small, practical units in tenant-rich areas such as Mapo / Gongdeok, Sinchon / Ewha, Hongdae / Yeonnam, Gangnam Station / Yeoksam, and Jamsil, while avoiding prestige pricing that rent cannot support.

Neighborhoods and apartment rental yields in the 2026 Seoul apartment market

This table compares apartment rental yields in Seoul by neighborhood and apartment type.

For each area, the table shows estimated purchase price, estimated monthly rent, gross rental yield, and net rental yield for studios, 1-bedroom apartments, and 2-bedroom apartments. The raw Seoul dataset does not provide annual fees, occupancy, time to rent, main demand, main risk, or investment profile columns, so this table keeps the available figures unchanged rather than inventing missing values.

We have made this infographic to give you a quick and clear snapshot of the property market in South Korea. It highlights key facts like rental prices, yields, and property costs both in city centers and outside, so you can easily compare opportunities. We’ve done some research and also included useful insights about the country’s economy, like GDP, population, and interest rates, to help you understand the bigger picture.

Which neighborhoods offer the best net yield among areas people actually want to live in Seoul?

The best net-yield neighborhoods among livable Seoul areas are Mapo / Gongdeok, Gangnam Station / Yeoksam, Sinchon / Ewha, Hongdae / Yeonnam, Hannam, and Jamsil.

These areas combine above-average net rental yield in Seoul with tenant demand that is easier for a beginner buyer to understand. The demand comes from universities, offices, transport access, family infrastructure, or central commuting routes.

Sinchon / Ewha has the strongest studio number in the dataset. A studio is modeled at ₩300m and ₩1.10m monthly rent, giving 4.4% gross yield and 2.9% net yield.

Mapo / Gongdeok is less flashy but more balanced. Its studios, 1-bedroom apartments, and 2-bedroom apartments all sit around 2.7% net yield, which suggests the income case does not depend on only one apartment type.

Hannam also shows high net yields, especially for 1-bedroom apartments at 2.9% and 2-bedroom apartments at 3.0%. The caution is that Hannam is not a uniform apartment market, so building selection matters more than the neighborhood average.

For a beginner buyer, the practical takeaway is simple: Sinchon / Ewha and Hongdae / Yeonnam can give stronger headline yield, while Mapo / Gongdeok and Jamsil give cleaner tenant depth and easier long-term interpretation.

Where can I find apartments with above-average yields and below-average entry prices in Seoul?

The clearest Seoul neighborhoods with above-average yields and below-average entry prices are Sinchon / Ewha, Hongdae / Yeonnam, Mapo / Gongdeok, and smaller older-stock options in Hannam.

These areas are much cheaper than Apgujeong, Banpo, Daechi, or Oksu, but their rents remain strong enough to support better apartment rental yields in Seoul.

Sinchon / Ewha is the clearest low-entry example. A studio costs about ₩300m and rents for about ₩1.10m per month, giving 4.4% gross yield and 2.9% net yield.

Hongdae / Yeonnam studios are also attractive on entry price. The dataset puts a studio at about ₩360m with ₩1.25m monthly rent, equal to 4.2% gross yield and 2.7% net yield.

Mapo / Gongdeok is slightly more expensive, but still rational. A studio is modeled at ₩390m with ₩1.22m monthly rent, and a 1-bedroom apartment is modeled at ₩630m with ₩1.95m monthly rent.

The reason these areas work is not simply cheapness. The real signal is tenant purpose: students in Sinchon / Ewha, young lifestyle renters in Hongdae / Yeonnam, and cross-Seoul commuters in Mapo / Gongdeok.

Where does the rent level justify the purchase price most clearly in Seoul?

The rent level most clearly justifies the purchase price in Sinchon / Ewha, Mapo / Gongdeok, Hongdae / Yeonnam, Gangnam Station / Yeoksam, and selected Hannam stock.

These Seoul neighborhoods show a better rent-to-price relationship because tenants have practical reasons to pay rent there, while purchase prices are not always as inflated as the most prestigious districts.

Sinchon / Ewha has the strongest rent-to-price signal. A studio at ₩300m and ₩1.10m monthly rent produces 4.4% gross yield, which is more than double the Apgujeong studio gross yield of 2.1%.

Mapo / Gongdeok is also rational. Its 1-bedroom apartment is modeled at ₩630m with ₩1.95m monthly rent, equal to 3.7% gross yield and 2.7% net yield.

Gangnam Station / Yeoksam works because renters pay for jobs, subways, academies, restaurants, nightlife, and short commutes. A studio at ₩500m with ₩1.50m monthly rent gives 3.6% gross yield and 2.5% net yield.

The honest interpretation is that Seoul rent rarely fully rewards prestige pricing. Rent supports purchase price better in practical renter districts than in trophy apartment districts.

Where is the best place to buy if I want stable rental income rather than maximum yield in Seoul?

The best Seoul neighborhoods for stable rental income are Jamsil, Mapo / Gongdeok, Yeouido, Daechi, and Mok-dong.

These areas may not always produce the highest net rental yield in Seoul, but they have stronger tenant depth, clearer resale logic, and more predictable renter profiles.

Jamsil is a good example. A 2-bedroom apartment is modeled at ₩1.14bn and ₩3.35m monthly rent, producing about 3.5% gross yield and 2.5% net yield.

Mapo / Gongdeok is strong because it serves several renter groups at once. It works for office workers, couples, commuters, and renters who want access to central Seoul, Yeouido, Seoul Station, and western Seoul.

Yeouido is lower-yielding but stable. A 2-bedroom apartment rents for about ₩3.25m per month and produces about 2.4% net yield, supported by the office district and professional tenants.

Daechi and Mok-dong are family-stability markets. Their apartment demand is supported more by education logic, schools, and family infrastructure than by short-term lifestyle renters.

Which apartment type gives the best return for the lowest total investment in Seoul?

The apartment type that gives the best return for the lowest total investment in Seoul is usually the studio apartment, followed by the small 1-bedroom apartment.

Studios are cheaper to buy and often produce the best rent per won invested. This matters in Seoul because the starting price for even small apartments can be high.

Sinchon / Ewha studios show the clearest example. The modeled purchase price is ₩300m, the monthly rent is ₩1.10m, and the net yield is 2.9%.

Hongdae / Yeonnam studios also work well, with a modeled purchase price of ₩360m, monthly rent of ₩1.25m, and 2.7% net yield.

1-bedroom apartments are often the better all-round product. In Mapo / Gongdeok, a 1-bedroom apartment costs about ₩630m and rents for about ₩1.95m per month, giving 2.7% net yield while attracting a broader tenant base than a studio.

Two-bedroom apartments produce higher absolute rent, but they usually require much more capital. In Banpo, the 2-bedroom rent is ₩4.05m per month, but the purchase price is ₩1.7bn, leaving only 2.0% net yield.

We give you more details in the our real estate pack about Seoul.

Which neighborhoods offer strong rental income with the lowest vacancy risk in Seoul?

The Seoul neighborhoods that offer strong rental income with lower vacancy risk are Jamsil, Mapo / Gongdeok, Yeouido, Daechi, and Gangnam Station / Yeoksam.

These areas have strong rent because the tenant base is deep, not only because the neighborhood is expensive.

Jamsil 2-bedroom apartments rent for about ₩3.35m per month, supported by families, large apartment complexes, schools, retail, sports facilities, and southeastern Seoul job access.

Mapo / Gongdeok has a different kind of safety. The net yield is about 2.7% across all three apartment types, which suggests balanced demand across studios, 1-bedroom apartments, and 2-bedroom apartments.

Gangnam Station / Yeoksam is strongest for compact units. Studios rent for about ₩1.50m per month and 1-bedroom apartments rent for about ₩2.35m, supported by office workers and single professionals.

The practical takeaway is that low vacancy risk in Seoul usually costs money. The best compromise is not the cheapest neighborhood, but the area where rent, access, tenant depth, and resale liquidity all line up.

It provides a clear view of how this country positions itself as a real estate investment destination, which might interest you if you’re planning to invest there.

Which areas look overpriced relative to their rental income in Seoul?

The Seoul areas that look most overpriced relative to rental income are Apgujeong, Banpo, Oksu, and parts of Seongsu.

These can be excellent places to live or hold for long-term capital preservation, but the rental-yield case is weak.

Apgujeong is the clearest example. A 1-bedroom apartment is modeled at ₩1.55bn and ₩2.85m monthly rent, giving only 2.2% gross yield and 1.5% net yield.

Banpo has a similar issue. A 2-bedroom apartment rents for about ₩4.05m per month, but the purchase price is about ₩1.7bn, leaving only 2.0% net yield.

Oksu has strong central access and Han River appeal, but rents do not fully match purchase prices. Its 1-bedroom apartment shows only 2.0% net yield.

Seongsu is more complicated. Net yields around 2.5% to 2.6% are not terrible for Seoul, but the Seoul Forest and creative-district story has already been partly priced into purchase values.

Which neighborhoods should I avoid even if the rental yield looks attractive in Seoul?

Beginner Seoul rental investors should be careful with Hannam older stock, Hongdae / Yeonnam small units, and Sinchon / Ewha studios, even when the rental yield looks attractive.

The issue is not that these neighborhoods are bad. The issue is that the attractive yield can depend heavily on buying the right building, floor, layout, access point, and tenant format.

Hannam shows strong numbers, with 1-bedroom apartments at 2.9% net yield and 2-bedroom apartments at 3.0% net yield. But Hannam is uneven because older apartment stock, luxury compounds, villas, and international demand sit close together.

Hongdae / Yeonnam studios show 2.7% net yield, but rental performance depends heavily on furnishing, noise exposure, building quality, and tenant turnover.

Sinchon / Ewha studios reach 2.9% net yield, but the tenant base is more student-linked and price-sensitive. A clean unit near transport can work well, while a dark or poorly maintained unit can disappoint.

The practical rule is to avoid weak versions of high-yield areas. In Seoul, a good neighborhood label cannot fix a poor building or an inconvenient micro-location.

Which neighborhoods look risky even though the rental yield is high in Seoul?

The Seoul neighborhoods that look risky despite high yield are Sinchon / Ewha, Hongdae / Yeonnam, and parts of Hannam.

These areas can produce attractive net rental yield in Seoul because purchase prices are lower relative to rent, but the tenant base can be less stable than in Jamsil or Mapo / Gongdeok.

Sinchon / Ewha studios show the best net yield in the dataset at 2.9%. The risk is that demand is exposed to students, young renters, and affordability pressure.

Hongdae / Yeonnam has strong lifestyle demand, with studios at 2.7% net yield and 1-bedroom apartments also at 2.7%. The risk is higher turnover and more sensitivity to noise, furnishing, and building management.

Hannam can look especially attractive, with 2-bedroom apartments at 3.0% net yield. But the higher yield may reflect discounts for older buildings, maintenance issues, parking limitations, or less standardized layouts.

A safer alternative is Mapo / Gongdeok. The top-end yield is slightly lower than Sinchon / Ewha, but the demand base is broader and less dependent on one renter group.

What neighborhoods should I avoid when buying a rental apartment in Seoul?

For a beginner Seoul rental investor, the areas to avoid are ultra-expensive low-yield entries in Apgujeong, weakly selected older Hannam stock, and poorly located student-area studios in Sinchon / Ewha.

This is not a full-neighborhood ban. It is a warning against buying apartments where the rent does not properly compensate for the price, risk, or management burden.

Apgujeong should be avoided by yield-focused beginners because the income return is too thin. Studios and 1-bedroom apartments both show about 1.5% net yield.

Older Hannam stock should be approached carefully. The yields look strong, but maintenance, access, parking, building quality, and tenant fit can change the result sharply.

Sinchon / Ewha should not be avoided completely. It should be avoided only when the unit is poorly located, old, unfurnished, hard to manage, or too dependent on student demand.

The simple beginner rule is this: avoid Seoul apartments where the only attractive number is the low purchase price, or where the only investment story is prestige.

Which neighborhoods are seeing rental demand weaken, and why, in Seoul?

The Seoul neighborhoods most exposed to weakening rental demand are premium low-yield areas where prices moved faster than rents, plus weaker small-unit student or lifestyle micro-locations.

In this dataset, that mainly means Apgujeong, Banpo at current prices, Seongsu after rapid repricing, and weaker Sinchon / Ewha buildings.

The issue in Apgujeong and Banpo is not weak desirability. It is rental-income compression. Apgujeong 2-bedroom apartments rent for about ₩4.60m per month, but the purchase price is modeled at ₩2.3bn, leaving only 1.6% net yield.

Banpo 2-bedroom apartments rent for about ₩4.05m per month, but the purchase price is about ₩1.7bn, leaving about 2.0% net yield. That is stable, but it is not compelling for income buyers.

Seongsu has a different risk. Rents are still high, but purchase prices have already absorbed much of the Seoul Forest and creative-district premium.

In Sinchon / Ewha, the weakening risk is micro-local. Good units near stations and universities can rent well, but older or poorly maintained units face more competition from budget-sensitive renters.

Which neighborhoods are seeing new developments that could create stronger rental demand in Seoul?

The Seoul neighborhoods where new development could create stronger rental demand are Yongsan / Hannam, Yeouido, Sangam / Mapo, and southeastern Seoul around Gangnam access corridors.

The key distinction is demand-creating development versus supply-heavy development. New offices, transit, retail, cultural uses, and mixed-use districts can deepen the tenant pool, while more apartments alone can create competition.

Yongsan is the clearest medium-term story because the Yongsan International Business District is planned as a major mixed-use area linking Seoul Station, Yongsan Station, and the Han River.

That matters for Hannam and nearby Yongsan-area apartments because new office, hotel, retail, and cultural demand can support professional and international tenants. The caution is that much of the Yongsan story is already known by buyers.

Sangam / Mapo also has a development angle because media, entertainment, park, and Han River access can support renter demand across western Seoul.

For Gangnam-linked districts, future transport and access improvements can help compact rental demand. But buyers should be careful because Seoul prices can move before the rent improvement actually appears.

Which neighborhoods are becoming more attractive to renters because of recent infrastructure or transport changes in Seoul?

The Seoul areas becoming more attractive to renters because of infrastructure and transport logic are Suseo / Gangnam access areas, Mapo / Seoul Station-linked areas, Yongsan, and future Sinsa-connected southeastern corridors.

Transport matters in Seoul because commute time is one of the biggest renter filters. A similar apartment can rent better when it gives a cleaner route to offices, universities, hospitals, or major transfer nodes.

Gangnam Station / Yeoksam already benefits from this logic. The dataset shows studios at ₩1.50m monthly rent and 1-bedroom apartments at ₩2.35m monthly rent, supported by jobs, subway access, and dense everyday amenities.

Mapo / Gongdeok is another practical access market. It connects renters to central Seoul, Yeouido, Hongdae, Seoul Station, and western Seoul, which helps explain why all three apartment types show about 2.7% net yield.

Yongsan is more of a central redevelopment and transfer-node story. If new office and mixed-use demand grows, nearby rental markets such as Hannam could benefit, although the investment case depends heavily on the entry price.

The risk is priced-in optimism. A future transport story is useful, but a beginner buyer should still ask whether today's rent already supports today's purchase price.

Which neighborhoods have become less attractive for apartment investors over the last 12 months in Seoul?

The Seoul neighborhoods that have become less attractive for rental-income investors are Apgujeong, Banpo, Seongsu, and Oksu.

These neighborhoods may still be excellent residential areas. The problem is that prices are high enough to weaken the income case for a buyer focused on net rental yield in Seoul.

Apgujeong is the clearest case. A studio costs about ₩980m and rents for about ₩1.75m per month, which produces only 1.5% net yield.

Banpo is also a stability market rather than a high-return market. Its 1-bedroom apartment shows 1.9% net yield, while its 2-bedroom apartment shows about 2.0% net yield.

Seongsu remains interesting, but the margin of safety is smaller because the area has become expensive. Net yields around 2.5% to 2.6% are acceptable, but not obviously cheap for the risk.

Oksu is not weak, but it is expensive relative to rent. A 1-bedroom apartment is modeled at ₩900m with ₩2.15m monthly rent, leaving about 2.0% net yield.

Which apartment types are becoming harder to rent in Seoul, and in which neighborhoods?

The apartment types becoming harder to rent in Seoul are overpriced 2-bedroom apartments in premium districts, poorly located studios in student areas, and older small apartments without modern finishes.

The weakness is not citywide. It is unit-specific, which means the wrong apartment can underperform even in a famous neighborhood.

In Apgujeong and Banpo, 2-bedroom apartments are expensive to buy, so the rent rarely justifies the price. Apgujeong 2-bedroom apartments rent for about ₩4.60m, but the purchase price is about ₩2.3bn, producing only 1.6% net yield.

Banpo 2-bedroom apartments rent for about ₩4.05m per month, but the modeled purchase price is about ₩1.7bn. The net yield is only about 2.0%.

In Sinchon / Ewha, studios still have the best modeled yield, but weaker units can be harder to rent because students and young renters are budget-sensitive. Clean, well-located studios work better than old or poorly furnished ones.

In Hongdae / Yeonnam, studios and 1-bedroom apartments depend heavily on lifestyle demand. Units close to noise, with poor access, or with weak building management can suffer higher turnover even when the headline rent looks good.

For a beginner in Seoul, the safest apartment type is usually a well-located 1-bedroom apartment. It avoids the highest studio turnover while requiring much less capital than a family-sized 2-bedroom apartment.

INSIGHTS

These insights are drawn from the Seoul apartment rental yield dataset, with a focus on what a foreign individual buyer should understand before buying a residential apartment to rent out.

You’ll find even more insights in our our real estate pack about Seoul.

  • Seoul is a low-yield apartment market compared with many foreign investors' expectations. A good net yield in this dataset is often around 2.7% to 3.0%, not 5% or 6%.
  • Studios usually produce the strongest rental return because small apartments monetize renter budgets more efficiently. Sinchon / Ewha studios reach 2.9% net yield, while most premium 2-bedroom apartments sit much lower.
  • Mapo / Gongdeok is one of the most balanced Seoul apartment markets in the dataset. The 2.7% net yield across all three apartment types suggests unusually broad tenant demand.
  • Gangnam Station / Yeoksam is a work-driven rental market, not a prestige-only market. Its studio yield is supported by office workers, subway access, nightlife, restaurants, and short commutes.
  • Sinchon / Ewha has the strongest studio math, but the buyer must respect student-market risk. The yield is attractive only if the unit is clean, well-located, and easy to rent.
  • Hongdae / Yeonnam works best when the unit matches lifestyle demand. Furnishing quality, noise, street access, and building management matter more than the neighborhood name alone.
  • Hannam's high yield should be interpreted carefully. Higher numbers can reflect older buildings or uneven stock, not just stronger income demand.
  • Apgujeong is a weak income investment even though it is one of Seoul's safest prestige addresses. The net yield of about 1.5% on studios and 1-bedroom apartments means the buyer is mostly betting on capital value.
  • Banpo and Daechi are stability plays, not high-yield plays. Their demand is supported by schools, family preferences, and blue-chip residential status, but prices absorb much of the rent.
  • Jamsil is useful for buyers who want family tenant depth. The 2-bedroom apartment net yield of about 2.5% is not the highest, but the tenant pool is deeper than in many more volatile lifestyle areas.
  • Oksu shows why good central access does not automatically mean good rental yield. Han River appeal and centrality can lift prices faster than rents.
  • Seongsu has a real rental story, but much of the lifestyle premium is already priced in. Investors should not assume the creative-district narrative will automatically improve yield.
  • Mok-dong is a patient family-demand market. It is more convincing for stable tenants than for maximum current income.
  • Yeouido is stable but capped by purchase prices. The office-worker demand is real, but the net yield is mostly around 2.3% to 2.4%.
  • The most important Seoul investment mistake is confusing desirability with yield. A famous address can be easy to sell and still produce weak rental income.
  • Foreign buyers should compare net yield, not only gross yield. Vacancy, agent fees, maintenance, repairs, tax friction, furnishing, and deposit-based lease structures can change the real return.
  • The best beginner strategy is to buy tenant depth. In Seoul, that often means compact apartments near transport, jobs, universities, or family infrastructure, not simply the cheapest possible unit.

OUR METHODOLOGY TO BUILD THIS TRACKER

To estimate purchase price, monthly rent, and rental yield in different Seoul neighborhoods, we built the analysis manually from the ground up by neighborhood and apartment type. We did not reuse a third-party yield dataset.

For each area, we researched current residential sale listings and rental listings across major Korean real estate platforms such as Naver Real Estate, Zigbang, and Dabang.

First, we collected comparable sale listings for each Seoul neighborhood and apartment type. We then cleaned the sample and kept only reasonably comparable properties based on location, apartment type, size, condition, listing quality, and market relevance.

We removed duplicates, unrealistic asking prices, luxury outliers, distressed assets, serviced-style offers, incomplete listings, and other properties that would distort the estimate. Sale prices were then interpreted using the median price as the main reference where possible, or the average only when the sample was clean.

We built the rental side of the dataset separately. For the same neighborhood and apartment type, we manually collected rental listings, removed outliers and non-comparable listings, and estimated a realistic monthly rent using the median rent where possible.

Purchase prices and rents were researched separately, then matched by neighborhood and property type to estimate gross rental yield. The gross rental yield was calculated as annual rent divided by estimated purchase price.

To estimate net yield, we did not apply one flat discount to every apartment. The deduction was adjusted by neighborhood and apartment type, reflecting vacancy risk, agent fees, maintenance, management costs, repairs, tax friction, furnishing needs, building costs, service charges, and the way some Seoul rentals include deposits rather than pure monthly rent.

Each estimate was assigned a confidence level based on the quality and size of the comparable listing sample. Around 30 to 40 comparable listings means higher confidence, 20 to 30 comparable listings means usable but less robust, and fewer than 20 comparable listings means directional only unless the comparable area was widened.

These estimates are updated regularly and should be read as structured market estimates, not guarantees of future rental income. Honesty, quality, and rigor are at the core of our work, and they are also what you will find in our real estate pack about Seoul.
