The housing index in Germany for the second quarter of 2026 sends a clear signal: rents are rising faster than purchase prices. The Cologne Institute for Economic Research (IW) reports a year-on-year rent increase of four percent, while property prices have only added 0.8%. The market is thus continuing to diverge – the dynamics of rents are strengthening, while purchase prices are stabilizing.
However, the increase in rents is uneven. The seven largest cities report a growth of 2.9%, while their surroundings see a rise of 3.7%. The most significant jumps come from other large cities, where rents have jumped by 4.9% year-on-year. Cologne even reports a nalmost 8% increase. In contrast, Düsseldorf is the only major city to have seen a slight decline. This regional disparity confirms that the rental housing market is further splitting according to local conditions.

Meanwhile, purchase prices are holding steady. Apartments have only increased by 0.2%, while houses have risen by one percent. In some metropolises, prices are even declining, such as in Berlin or Frankfurt. The dynamics are driven more by regions outside the main centers, where growth remains above one percent. IW points out that despite the slight increase, the market remains below the price peak of 2022. However, buyers continue to face challenging financing, which hampers demand.
An interesting perspective is also on the number of listings. Sales advertisements have doubled in the largest cities since 2022, with listings for apartments even increasing by more than 160%. However, this is not a boom in new properties, but rather a longer selling period caused by high prices and expensive loans. The opposite trend is seen in rentals: supply is decreasing, with a drop of 57% in Hamburg. IW explains this by low mobility and insufficient new construction.
For those interested in housing, it is therefore crucial to monitor local supa-data. Or are you more attracted to investment opportunities? Check out the situation with investment apartments in German cities.
