GREIX Rental Price Index Q4 2025: Rental prices are rising faster again - proportion of fixed-term contracts and furnished apartments is at a record high

By the end of 2025, the rate at which asking rents rose in German cities was faster than general inflation. Compared to the previous quarter, rents increased by an average of 1.0 percent nationwide, and by as much as 4.5 percent compared to the previous year. The proportion of fixed-term and furnished rental properties reached a record high. This is reflected in the latest update of the GREIX rental price index, published by the Kiel Institute for the World Economy. The index analyzes asking rents for apartments based on data from the “VALUE Marktdatenbank” across 37 German cities and regions, including the 30 largest cities.
