Property price data sources in Czechia: ČSÚ, ČNB, the cadastre and portals

A transaction-based statistic with a level, and a cadastre that sells prices

Czech residential price data is richer than its neighbors' on one point: the official statistics are built on transaction prices and are published as a level in crowns per square meter, not only as an index. The Český statistický úřad (ČSÚ) publishes average purchase prices of flats, family houses and building land by region and year, quarterly indices of realized prices for older and new flats, an index of offered prices, and the harmonized house price index (HPI) that Eurostat republishes. Its 2025 release, published on 15 July 2026, puts the average flat at 72,410 CZK per square meter nationally and 131,520 CZK in Prague, the average family house at 56,066 CZK nationally and 119,239 CZK in Prague, and the aggregate year-on-year index at 109.0.

The source of those numbers changed in 2020. Until then the ČSÚ series rested on the tax returns filed for the property acquisition tax. That tax was abolished on 26 September 2020, the data source ceased to exist, and the publication "Ceny sledovaných druhů nemovitostí" was discontinued, with its last edition on 31 December 2020 covering 2019. ČSÚ announced on 26 February 2021 that it was preparing a replacement built on the cadastre database, and on 30 December 2022 it published "Ceny nemovitostí" for 2019 to 2021 together with regional index time series from 2015. The current statistics therefore combine administrative data from the cadastre with ČSÚ's own surveys of new dwellings, interviewer surveys of older dwellings and internet price monitoring.

What the country does not have is a free, bulk register of individual sale prices. The cadastre run by the Český úřad zeměměřický a katastrální (ČÚZK) records purchase prices, but the free public viewer shows parcels, buildings, units and proceedings without them, and the price records are provided through the paid remote-access service under Decree 358/2013 Coll., per record. That gap is why portal asking prices, a municipal price map for building land, private price maps and agency-reported sold prices all have a role, and the sections below set out what each one actually contains.

Source inventory

Every public source of Czech residential price information, with what it actually holds. The ČSÚ rows and Eurostat give official statistics; the cadastre rows give the legal record; the remaining rows are commercial or municipal products that sit on top of the same inputs.

ČSÚ: from tax returns to cadastre records

The statistical office's methodology names three routes into its price statistics. New dwellings are surveyed directly from developers on the form Ceny NB 1-04. Older dwellings are covered by interviewer surveys and by internet price monitoring, which is the input to the offered-price index. And administrative data come from ČÚZK, the cadastre, which since the loss of the tax data has been the backbone of the realized-price statistics. ČSÚ describes the HPI and the owner-occupied housing price index (OOHPI) as internationally comparable within the EU, publishes quality reports for both under Regulation (EU) 2016/792, and states that price indices are revised when the following reference period is published, so any vintage comparison has to note the release date.

The annual product is the most quoted. "Ceny nemovitostí" gives average purchase prices and indices for flats, family houses and building land by region, with Prague broken out, and the public database serves three table families: average purchase prices in territorial comparison (CEN13A), average prices as time series (CEN14A) and price indices in territorial comparison (CEN15A1). The 2025 edition reports flats up 10.6 percent and family houses up 6.7 percent year on year, with the aggregate index at 109.0. Because the series rests on the cadastre from 2019 onward and on tax returns before, a long comparison across 2019 to 2021 should be read with the source change in mind.

The quarterly products are the ones analysts use for turning points: an index of realized prices of older flats, an index of realized prices of new flats, an index of offered prices of flats, and the HPI with its new and existing dwelling components. The realized indices split Prague from the rest of the country, which matters because the capital moves first and furthest. The offered-price index, built on the same internet monitoring that portal data provides, is the official bridge between asking and transaction prices and the best public check on whether a portal-based series is tracking the market or the advertised stock.

Eurostat and the Czech National Bank

Eurostat republishes the ČSÚ house price index as the Czech column of the quarterly dataset prc_hpi_q, released about one quarter and one week after the reference period. The 2 July 2026 release shows annual changes of 10.5, 10.8, 10.3 and 10.0 percent for Q2 2025 through Q1 2026, a plateau at double-digit growth rather than the acceleration or cooling seen in some neighboring markets. The index follows Regulation (EU) 2016/792 and its implementing Regulation (EU) 2023/1470: all dwellings bought by households, new and existing, market transactions only, national statistical institutes compiling and Eurostat assembling the aggregates. It gives changes, not levels, and no regional detail.

The Česká národní banka is not a producer of price data but the most influential reader of it. Its Financial Stability Report, published in spring, typically June, and in autumn, typically December, since 2018, carries the bank's own assessment of whether flat prices stand above or below the level that household incomes, rents and interest rates justify, and it is the vehicle for the macroprudential limits on loan-to-value, debt-to-income and debt-service ratios that shape what buyers can pay. Its analysis draws on the ČSÚ realized and offered indices, on portal data and on lender valuation data, so when a bank or an insurer cites "ČNB figures" for house prices, the underlying number is usually one of the ČSÚ series with a valuation judgment on top.

What the ČÚZK cadastre publishes, and what it charges for

The Czech cadastre is the country's legal property record and the only place where individual purchase prices exist as data. Its public viewer, Nahlížení do katastru nemovitostí, requires no registration and is free; it returns selected data on parcels, buildings, units (flats or non-residential spaces) and building rights, and the status of proceedings. Prices are not among the selected data. Ownership itself is shown in summary, and the full ownership sheet, the price records and the documents behind an entry belong to the paid services.

Those paid services are Dálkový přístup, in two versions: DP for registered users, primarily legal entities, who are billed at agreed intervals, and DPN for unregistered users, primarily individuals, who pay online and verify their identity through Citizen Identity for some outputs. Fees are set by Decree 358/2013 Coll. on the provision of cadastral data, whose appendices 4 and 5 price the remote-access outputs. Price data are provided as part of these outputs for the transfers on which a price was recorded, per proceeding rather than as a downloadable file, and the bulk exchange formats that ČÚZK sells contain the descriptive file, the digital map and raster data for a territorial unit rather than a transaction feed. In practice a buyer can learn what a specific flat sold for, at a cost per record; nobody can download a street's worth of sales for free.

Prague adds a second cadastre-linked price product that is often confused with market data. The Cenová mapa stavebních pozemků hl. m. Prahy, published by IPR Praha with ČÚZK, is the municipal price map of building land issued under the city's price-map decree, with the current map effective from 1 January 2026 and history back to 2000, searchable by parcel or address on the web and in mobile apps. It exists for administrative valuation under the valuation decree, not to report what buyers paid, and it covers land, not flats. It is useful as a consistent, parcel-level floor for land value and useless as a comparable for a sale.

Price maps, sold-price aggregators and consultancy indices

Several private products fill the gap between the official indices and the paid cadastre records. Cenová mapa at cenovamapa.org, published by Dataligence with Deloitte, offers value estimates by locality behind a free registration and is the public face of the Deloitte Real Index, a quarterly index of realized flat prices that the consultancy has published for years. reas.cz shows sold properties with the realized price, the price per square meter and the sale date as reported by the agents and agencies that use the platform: 7,542 sales since 11 September 2024 are visible without an account and a further 41,266 behind login, which makes it the largest openly visible set of Czech realized prices, with the caveat that it is a self-reported sample rather than a census. Flat Zone aggregates developer projects and their offered new-build prices with sales progress, free to search and with paid analytical reports, chiefly for Prague and the large regions. Mortgage lenders publish their own indices from valuation data, the HB Index of ČSOB Hypoteční banka being the longest running.

The portals underneath all of this are sreality.cz, the Seznam.cz portal, and bezrealitky.cz, the no-commission portal that also publishes market notes; its Q2 2026 note observes that asking prices of flats kept rising while the prices actually agreed increasingly diverged downward, which is exactly the wedge between the two price families that the ČSÚ offered-price and realized-price indices are built to measure. Portal data carry asking price, floor area, layout, condition, location and photographs for each advertised property, refreshed daily. Their weaknesses are structural: the same flat is often advertised by several agencies at different prices, offers are withdrawn or repriced without trace, the asking price is the seller's opening position, and the mix of what is advertised shifts with the season and the cycle. A median of raw offers therefore measures the advertised stock, not the market, unless duplicates are resolved and composition is held constant.

Asking prices versus transaction prices

The Czech sources cover both price families, which is rare in the region, but they still do not measure the same thing. The ČSÚ realized indices and Eurostat describe completed household purchases as recorded in the cadastre; the ČSÚ offered-price index, the portals and Flat Zone describe what sellers ask. The table sets out which family answers which question.

A working order for using the sources

A practical sequence for anyone building a Czech price view, from the official anchor to the granular signal.

1. 1

   Anchor on the ČSÚ realized indices

   Take the quarterly realized-price indices for older and new flats, Prague and the rest of the country, and the Eurostat HPI for the national direction. Note the release date, because indices are revised at the following reference period.

2. 2

   Add the annual level

   Use "Ceny nemovitostí" and the CEN13A and CEN14A tables for crowns per square meter by region. Remember the 2020 source change: cadastre-based from 2019, tax-return-based before.

3. 3

   Check the wedge with the offered-price index

   Compare the ČSÚ offered-price index with the realized indices for the same quarters. A widening gap, as bezrealitky.cz noted for Q2 2026, means portal medians are running ahead of the market.

4. 4

   Fill localities from portals and sold-price aggregators

   Below kraj level, deduplicated portal offers give the current asking level for any locality, and reas.cz gives a sample of realized prices with dates. Treat the first as a level for this month and the second as a calibration sample, not a census.

5. 5

   Buy cadastre records only where a single price matters

   For a specific transaction, the ČÚZK remote-access price record is the authoritative figure, priced per proceeding. For a market view it is the wrong tool; use the indices.

How a model combines these sources

A price model treats these sources as layers with different jobs. The transaction indices set the direction and the revision discipline, the annual ČSÚ averages set the regional level, realized-price samples calibrate the wedge between asking and agreed prices, and deduplicated portal offers supply the daily, property-level signal that is then mix-adjusted so that a change in what is advertised is not mistaken for a change in price. Availability by market is listed on the coverage page.
