Poland Real Estate Transaction Prices (RCN) – what apartments really sold for

Real prices from notarial deeds, not asking prices. Give any place in Poland – a city, a street, an address or coordinates – and get the median price per m², the price range, the trend and the individual transactions from Poland's official Real Estate Price Register (Rejestr Cen Nieruchomości, RCN).

Listing portals only show what sellers hope to get. This Actor shows what buyers actually paid, straight from the register kept by Polish counties and published by the Head Office of Geodesy and Cartography (GUGiK). Since February 2026 the register is free to access – this Actor turns it into clean, ready-to-use data.

What you get

1. Area report (one record per run)

• median price per m² with p10 / p25 / p75 / p90, mean, min and max
• median total price and median apartment size
• price per m² by number of rooms and by market (primary = from developer, secondary = resale)
• quarterly trend and year-over-year change
• how many transactions were found and why some were left out of the statistics

2. Individual transactions (newest first)

• deed date (or month for the newest deeds), total price, usable area, price per m²
• rooms (incl. kitchen, as recorded in the register), floor
• market type, seller and buyer type (person / company / municipality)
• street and building number, distance from your location, coordinates

Who uses it

• Investors and flippers – check the real exit price before you buy.
• Appraisers and lenders – comparable transactions in seconds.
• Real estate agents – show clients facts, not portal asking prices.
• Proptech and analysts – a clean, repeatable feed for models and dashboards.
• AI agents – call it through the Apify MCP server to answer "what do flats sell for near X?" with real data.

Use it from an AI assistant (MCP)

Connect the Apify MCP server to Claude, ChatGPT, Cursor or your own agent and ask, for example: "What did apartments sell for within 1 km of Rynek Główny in Kraków in the last two years? Give the median price per m² and the trend." The assistant calls this Actor and answers with official deed prices instead of listing prices.

Property types

• Apartments – the most complete data (recommended).
• Commercial units, garages / parking.
• Houses with land and land plots – provided as published (beta); prices often cover the whole deed.

Pricing (pay per event)

Event	Price
Area report (once per run, only when at least one transaction qualifies for the statistics)	$0.25
Transaction record	$0.003 each ($3 per 1,000)

A typical run – one area report plus 200 transactions – costs about $0.85. Set Include individual transactions to off to pay only for the report.

Data quality and privacy

• Source: Rejestr Cen Nieruchomości of GUGiK (public register, free since 13 Feb 2026) – the official bulk export, refreshed weekly, plus the register's live web service for the newest deeds.
• Deed dates: exact for deeds from the bulk export; since October 2026 the live web service publishes only the month of the newest deeds, so those have month filled and date empty (datePrecision: "month"). Trends and statistics work by month and are not affected.
• No personal data: no names, no flat numbers, no deed numbers, no notary offices – only the building address.
• Transactions are left out of statistics (but still listed) when the price covers a whole deed with several properties, only a share was sold, the sale was not on the free market, the date is invalid or the price per m² is implausible (below 35% or above 300% of the local median – typically discounted municipal flats). The reason is in excludedReason.
• Coverage: most counties publish to the national service, including Warsaw, Kraków, Wrocław, Poznań, Gdańsk, Łódź, Szczecin, Lublin and Katowice; a few do not yet (e.g. Bydgoszcz). Counties add deeds with a delay of a few weeks to several months – every report shows lastTransactionDate and adds a note when the newest deed is older than 4 months.

FAQ

Why "rooms incl. kitchen"? The register counts rooms the official way ("izby"), kitchen included. A typical 2-room flat has roomsInclKitchen = 3.

What does "whole city" do? It takes all transactions in the city's county – available for the 66 cities with county rights (Warszawa, Kraków, Wrocław, Łódź, Poznań, Gdańsk and others).

Parking spaces? In shared garages a parking space is sold as a share of the whole garage. Such records are kept with their price per space (priceScope: "parking_space_share") and without a price per m².

My address was not found. Use Polish characters ("Świdnicka", not "Swidnicka") or paste coordinates like 51.1079, 17.0385.
