Korea Apartment Prices in English: Sale, Rent & Monthly Medians

Source: Ministry of Land, Infrastructure and Transport (MOLIT), Republic of Korea, via the Public Data Portal (data.go.kr)

This Actor translates field names into English, romanizes place names and converts units (10,000 KRW → KRW, m² → pyeong and ft²). It also romanizes apartment complex names (keeping the Korean originals), normalizes dates to ISO 8601, adds USD amounts at an exchange rate you choose, and can calculate monthly summary statistics. The transaction figures themselves are not changed. Every record has a source field with this attribution and the dataset URL.

Search any Korean district by its English name and get official MOLIT apartment sale and rent (jeonse / monthly rent) records, plus monthly median summaries if you want them. No data.go.kr account or API key needed.

• English district search. Type Gangnam-gu, Seoul Gangnam, Bundang or Haeundae; Korean (강남구, 서울 강남구) and 5-digit codes (11680) work too. All of Korea's ~250 si/gun/gu are covered, and a city name such as Seoul expands to every district in it.
• Sales and rents in one run. MOLIT's detailed apartment sale records and its jeonse / monthly-rent records, side by side.
• Monthly medians. Optional summary rows per district and month: transaction count, median / min / max price and median price per m² (for rents: deposit and median monthly rent).
• Analysis-ready fields. English keys, romanized names next to the Korean originals, KRW integers, m² / pyeong / sqft, ISO dates.
• No API key needed. The Actor uses its own data.go.kr key. You can still pass your own key for large jobs.

Typical users: foreign real-estate investors and analysts, proptech developers, journalists and researchers covering the Seoul housing market.

How to use

1. Enter one or more districts, for example Gangnam-gu, Seoul Seocho-gu, 마포구 or 11680.
2. Pick the deal type (sales, rentals, or both) and the contract months (YYYY-MM). By default you get the last 3 months plus the current month.
3. Optionally filter by exclusive area or apartment name, turn on summary rows, or add a USD/KRW rate.
4. Run the Actor and download the dataset as JSON, CSV, Excel or via the API. The dataset has three views: Sales, Rentals and Summary.

District names

• English: Gangnam-gu, Gangnam, Gangnam District, Seoul Gangnam, Gangnam-gu, Seoul
• Korean: 강남구, 강남, 서울 강남구, 서울특별시 강남구
• Code: 11680 (the first 5 digits of the legal-dong code, LAWD_CD)
• Districts inside a city: Bundang-gu, Seongnam Bundang-gu, 성남시 분당구
• Whole cities and provinces: Seoul, Busan, Suwon, Gyeonggi-do expand to all their districts
• Ambiguous names (Jung-gu, Seo-gu, Goseong-gun, Gwangju, Jeju) stop the run with a list of candidates. Add the city or use the code.

Recent reorganizations are handled: Gwangju and Jeollanam-do merged into Jeonnam-Gwangju (code 12) in 2026, Incheon's Jung-gu, Dong-gu and Seo-gu became Jemulpo-gu, Yeongjong-gu, Seohae-gu and Geomdan-gu, and Hwaseong-si and Bucheon-si were split into districts. Old names (Gwangju Dong-gu, Incheon Seo-gu) and old codes (29110, 42110, 45111) still work and are mapped to the current districts; MOLIT files historical data under the current codes.

apartmentName is a romanized reference, not the official name. The exact name of the complex is apartmentNameKo; use it to identify, match or cite a complex. In apartmentName, common apartment brands and loanwords take their English spelling (자이 → Xi, 힐스테이트 → Hillstate, 아이파크 → I-Park, 래미안포레 → Raemian Forêt, 타워팰리스 → Tower Palace), the rest is Revised Romanization, and the parts are separated by spaces (마포그랑자이 → Mapogeurang Xi).

Pricing

The Actor is free to use during its launch period: there is no charge per result. You only pay for your own Apify platform usage, which is a fraction of a cent for a typical run (one district over four months takes about 4 seconds). The Pricing tab always shows the current price. If pay-per-event pricing is introduced later, it will be announced there before it applies.

Limitations

• Daily request limit. The Actor's built-in data.go.kr key allows about 10,000 API requests per day (Korea time), shared by all users. Each district × month × deal type is one request (more when a month has over 1,000 rentals), so Seoul's 25 districts × 12 months of sales is 300 requests. If a run needs more requests than are left for the day, it stops before calling the API and says so. Try again after midnight Korea time (15:00 UTC), or use your own free data.go.kr key in serviceKey.
• Reporting lag. Contracts must be reported within 30 days, so the most recent weeks are incomplete and fill up later. In a run on 2026-11-07, Seoul Jung-gu had 30 sales for October but only 3 for November. Re-run recent months for complete figures.
• Period. Up to 36 months per run, from January 2006 onward.
• Apartments only. Officetels, row houses and land are not covered.
• Cancellations. MOLIT keeps cancelled sales in the data and flags them. They are excluded by default (includeCancelled).
• Romanization. Place names follow the official Revised Romanization rules. apartmentName is a reading aid only: about 20 common brands and loanwords use their English spelling (Raemian, Xi, Hillstate, I-Park, Prugio, Lotte Castle, The Sharp, e-Pyeonhan Sesang, SK View, The H, Heights, Tower, Park, Central, Palace, Castle, City, View, Forest, Forêt, Ville, Apt), and other brand words are transliterated (래미안블레스티지 → Raemian Beulleseutiji, not "Blesstige"). The exact name is always apartmentNameKo. apartmentNameContains matches the Korean name, apartmentName and a letter-by-letter spelling, ignoring case, spaces and accents (Xi, raemian foret and Dogok for 도곡렉슬 all work).
• Personal data. The source data has no personal names. Buyers and sellers are only classified as individual, corporation, public or other.
