Data Info
This service is a free lookup tool that shows Korea's Ministry of Land, Infrastructure and Transport real-transaction disclosure system public API data as-is. It's unrelated to any brokerage or appraisal, and shows only actually-reported sale transactions.
Regional coverage
Currently covers 72 regions total: 25 districts in Seoul and 47 cities/districts in Gyeonggi. Other provinces will be added over time.
Update cycle and reporting delay
Since real-transaction reporting can happen up to 30 days after the contract, data for the most recent 1-2 months may show fewer records than the actual total. Counts increase as reporting catches up over time. Already-reported transactions that are later cancelled or corrected (e.g. due to a contract being voided) may take time to be reflected.
Price-per-pyeong calculation
The "₩X per pyeong" figure in the list divides the transaction amount by the reported net floor area, converted at 3.305785㎡ = 1 pyeong. Since this uses net area rather than gross area (net + common areas), it may differ from the price-per-pyeong figures commonly quoted by real estate agents.
Sort criteria
"Most recent" sorts by contract date, and "price/pyeong" sorts by the value from the calculation above. Price per pyeong may not display for some transactions lacking area data.
How does the transaction price differ from the asking price?
The transaction price is the amount actually contracted and reported, while the asking price commonly seen on real estate apps or at agencies is what the seller hopes to get. Since the actual contract price is settled through negotiation between buyer and seller — sometimes lower, sometimes higher than the asking price — the two figures inevitably differ. Even for the same complex and unit size, actual transaction prices can vary widely depending on floor, orientation, renovation condition, and market sentiment at the time of sale.
Frequently Asked Questions
Can I see actual listings on this site?
No, this service looks up past transactions reported to the Ministry of Land, Infrastructure and Transport. For actual listings or contracts, please use a real estate agency or property platform.
Why do transaction prices for the same complex vary so much?
Beyond individual factors like floor, orientation, or renovation status, interest rates and market sentiment at the time of transaction play a big role. It's common to see price differences of tens of millions of won for the same size within just a few months.
If a transaction price looks lower than market value, is the data wrong?
No. Transactions with special circumstances, like distressed sales or family transfers, are still reported and disclosed as-is, so looking at several transactions over the same period gives a better sense of market value than one unusually low or high transaction.
