IWH European Real Estate Index (EREI)

The IWH European Real Estate Index is a new dataset that illustrates developments in the European real estate market. Besides quoted (listing) prices, our data allows users to assess supply-side depth (number of listings) as well as market liquidity (dwell time). The dataset combines data originally sourced by the IWH as well as data for Germany from a project by RWI Essen (doi.org/10.7807/immo:redx:v3). EREI data is available in a monthly frequency, aggregated at the NUTS-3 level. Please refer to IWH Technical Report 2/2026 for technical details and coverage.

European Real Estate Index (EREI) 2026: A Near-real-time European Real Estate Index EREI: Monthly Listing Prices and Rents for Residential Real Estate

Michael Koetter Felix Noth Fabian Woebbeking

in: IWH Technical Reports, No. 2, 2026

Abstract

Real estate is a capstone connection between various economic agents and markets. It is the main store of household wealth, serves as collateral for mortgage loans in the banking system, aids the transmission of monetary policy, and can propagate financial crises when overvalued. Yet comparable house-price data across the European Union (EU) and the euro area is unavailable, which hinders the design and evaluation of common monetary and economic policy that operates across heterogeneous housing markets. We derive monthly subnational European Real Estate Indicators (EREI) from online residential property advertisements in 16 European countries. The release covers April 2024 to June 2026 and contains 48,168 region-month-segment observations for 1,154 NUTS 3 regions, aggregating more than 43 million listing observations across the monthly sale and rental cross-sections. Each region-month segment reports the number of advertisements and summary statistics for asking prices per square meter and listing durations. The release also includes sale-segment indices for Europe, the euro area, and individual countries. Thirteen covered countries are EU members, which represented 85% of EU-27 gross domestic product in 2024. EREI data support research on a wide range of socio-economic phenomena associated with real estate dynamics, such as the evaluation of monetary policy or macroprudential policy effects on financial stability.

Real Estate Transaction Taxes and Credit Supply

Michael Koetter Philipp Marek Antonios Mavropoulos

in: Journal of Financial Stability, Vol. 80 (September), 2025

Abstract

We exploit staggered real estate transaction tax (RETT) hikes across German states to identify the effect of house price changes on mortgage credit supply. Based on approximately 33 million real estate online listings, we construct a quarterly hedonic house price index (HPI) between 2008:q1 and 2017:q4, which we instrument with state-specific RETT changes to isolate the effect on mortgage credit supply by all local German banks. First, a RETT hike by one percentage point reduces HPI by 1.2%. This effect is driven by listings in rural regions. Second, a 1% contraction of HPI induced by an increase in the RETT leads to a 1.4% decline in mortgage lending. This transmission of fiscal policy to mortgage credit supply is effective across almost the entire bank capitalization distribution.

Aktuelle Trends: Immobilienpreise geben nach

Michael Koetter Felix Noth Fabian Woebbeking

in: Wirtschaft im Wandel, No. 2, 2025

Abstract

In turbulenten Zeiten, die von anhaltenden geopolitischen Krisen, dem holprigen Regierungswechsel in Deutschland und volatilen Aktienmärkten geprägt sind, mögen die eine oder der andere Investor auf Betongold setzen. Ob dies eine gute Idee ist, zeigt ein Blick auf die Dynamik im europäischen Häusermarkt.

European Real Estate Markets During the Pandemic: Is COVID-19 also a Case for House Price Concerns?

Michael Koetter Felix Noth

in: IWH Policy Notes, No. 3, 2022

Abstract

We use a new database on European real estate purchase and rental prices – the IWH European Real Estate Index – to document the relationship between staggered COVID-19 dynamics and real estate prices in 14 EU countries between January 2020 and December 2021. For most countries, we find no statistically significant response of monthly purchase and rental prices due to an increase of regional COVID-19 cases. For the UK we find that more COVID-19 cases depressed both purchase and rental prices significantly, but the economic magnitude of effects was mild during this sample period. In contrast, rents in Italy increased in response to hiking COVID-19 cases, illustrating the importance to consider heterogeneous crisis patterns across the EU when designing policies. Overall, COVID-19 dynamics did not affect real estate values significantly during the pandemic, thereby mitigating potential financial stability concerns via a mortgage lending channel at the time.

Kommentar: Immobilienbesitz in Inflationszeiten: Ein Damoklesschwert über der Finanzstabilität?

Michael Koetter

in: Wirtschaft im Wandel, No. 3, 2022

Abstract

Zu Beginn meines Studiums bot sich mir überall das gleiche Schauspiel: lange Warteschlangen anderer „Frischlinge“ vor dem neu renovierten WG-Zimmer samt modernstem 56k-Modem, fußläufig zu Uni und Lieblings-Café gelegen, mit happiger Miete zwar, aber irgendwie noch im finanziellen Lösungsraum. Eifrig bereitete ich tolle Argumente vor, warum gerade ich der optimale WG-Zuwachs sei, bevor ich mich einreihte. Schade, dass es dann meist jemand anderes wurde, aber nur kein Neid! Schade aber auch, dass die Suche nach einem Dach über dem Kopf für viele Menschen auch später frustrierend bleibt. Ein bezahlbares Zuhause zu suchen bleibt vielerorts ein von der Spaßsteuer befreites Unterfangen, ob nun für Berufseinsteiger oder die vierköpfige Familie, ob nun in Leipzig oder Köln.

Abstract

Seit dem Beginn der Pandemie sind die Angebotspreise für privat genutzte Immobilien EU-weit um ein Viertel, in Deutschland bis März 2021 um 45% gestiegen. Die Preisdynamik ist auch außerhalb der Ballungszentren beachtlich.
