Wohnimmobilienpreisindex

Wohnimmobilienpreisindex is an economic indicator that measures changes in the market value of residential real estate over time. It reflects average price developments for houses, apartments and other dwelling units within a defined geographical area, typically a country or region. The index is calculated using transaction data, such as sale prices recorded by property registries, or by applying hedonic regression models that adjust for characteristics like size, age, location and amenities.

The main purpose of the index is to provide policymakers, investors and researchers with a systematic way to gauge housing market dynamics. It assists governments in assessing the effectiveness of housing policies, informs monetary authorities about potential inflationary pressures, and helps real‑estate developers and buyers evaluate investment opportunities. In many national statistics offices, the Wohnimmobilienpreisindex is published monthly or quarterly, allowing for the monitoring of short‑term fluctuations as well as long‑term trends.

Sources for the index include administrative data from land registers and tax offices, survey data from real‑estate agents, and price indices developed by statistical agencies. Internationally comparable indices, such as those produced by OECD or Eurostat, enable cross‑border comparisons. While the index gives a generalized view of price movements, it may not capture the full complexity of local market variations, especially in heterogeneous housing stock segments.
