EREI sheds light on the dynamics in regional property markets already before official transaction-based data become available. The latest EREI figures provide an initial answer (see Figure 1). In July 2026, the asking-price index for Germany's sale segment rose by 1.2% month on month, while the EREI Europe aggregate edged down by 0.1%. Since March 2025, the increase has been 2.5% in Germany and 6.6% in the Europe aggregate. EREI makes these price developments visible for 1,154 small-scale regions in 16 European countries.

Real estate is of central importance to the economy and financial stability because it links the balance sheets of households, banks, and firms. Housing accounts for around 50–72% of households’ net wealth, depending on the wealth group. At the same time, real estate lending exposures made up almost 40% of euro area banks’ loans and advances in 2022. Changes in property values therefore affect wealth and consumption in the real economy as well as, collateral and bank risk in the financial system. Because financing structures, home ownership, and interest-rate fixation vary considerably across regions, even the common monetary policy in the euro area has markedly different local effects across Europe. The new data service EREI allows additional opportunities to analyse the spatial transmission of monetary and other policies.

EREI is based on online advertisements for residential property. Every month it reports asking prices per square metre, the number of listings and time on market for properties offered for sale and, where available, for rent. The published series starts in April 2024, and quality-checked monthly figures are generally released during the following month. EREI therefore complements official transaction-price statistics with faster, more geographically detailed signals (see Figure 2). A comparison with official transaction data confirms the reliability of the EREI in capturing regional price levels: in the five largest markets examined (Germany, the United Kingdom, France, the Netherlands, and Spain), EREI data closely track actual property transaction prices.
