ZIA-IW Real Estate Sentiment Index (ISI)

The IW's Real Estate Sentiment Index has been mapping the business situation of all companies in the German real estate market since 2014. Since the beginning of 2020, the survey has been compiled in cooperation with ZIA Zentraler Immobilien Ausschuss e.V. and published under the name ZIA-IW-Immobilienstimmungsindex (ISI). The index provides timely information on the situation and expectations of real estate companies, i.e. portfolio holders, investors, financiers and service providers of real estate as well as project developers. The survey of the management boards regarding their assessment of the business situation and expectations serves to provide a current and prospective assessment of the economic development and to increase the transparency of the German real estate market. Sub-indices for the four most important sub-markets (office, retail, residential, project developers) show a differentiated picture of the mood in the German real estate market.
