Korea Real Estate Transactions (Official MOLIT Data)

Get official South Korean property transaction prices as clean, English JSON / CSV / Excel. Every row is a real reported contract from the Ministry of Land, Infrastructure and Transport (MOLIT) real transaction price disclosure system, not a listing or an asking price.

Type a district name in English or Korean (Gangnam-gu, Seoul, 서울 강남구, Seoul), pick the property types and months, and get the deals.

What you can use it for

• Price research and valuation: real sale prices and price per m² / per pyeong for any apartment complex, by month.
• Rental market analysis: jeonse (lump-sum deposit) and monthly rent contracts, including renewals and previous rent.
• Investment and proptech models: feed a clean, consistent time series into dashboards, BI tools or AI agents.
• Market reports: count transactions by district and month, compare neighborhoods, track new-build premiums.

}

Rent rows have lease_kind (jeonse or monthly_rent), deposit_krw, monthly_rent_krw, contract_type (new / renewal), contract_term, and previous deposit / rent for renewals.

Prices are converted from the official unit (10,000 KRW) into plain KRW. Korean names are kept next to a romanized version (Revised Romanization), so you can join on either.

Pricing

Pay per result: $2 per 1,000 transactions. You only pay for rows saved to the dataset after filters, not for API calls.

Good to know

• Reporting lag: Korean law requires reporting within 30 days of the contract, so the latest 1 to 2 months keep filling in. Re-run recent months for complete counts.
• Privacy masking by the source: apartment floors are given but not unit numbers; some lot numbers for houses and land are partially masked (1***). This is how the government publishes the data.
• 2026 administrative changes: the source re-keys history under current district codes (for example the Jeonnam-Gwangju merger and new Hwaseong-si districts), and this Actor follows it. Inputs like Gwangju or 광주광역시 still work.
• Building names are reported by the source in Korean; building_name is a mechanical romanization, not an official English brand name.
