Interest rate turnaround makes differences between residential investment markets visible again
In the first half of 2026, asking rents in all city categories will continue their upward trend with high momentum. The rise in rents is widespread across all market segments. Against the backdrop of a persistent shortage of supply and continued high demand, the pressure on rental prices remains. The analysis by BNP Paribas Real Estate combines a well-founded classification of the rental housing markets with a differentiated view of the residential investment markets in the A, B and C cities since the interest rate turnaround. It offers institutional investors reliable guidance on the development of the investment and rental markets nationwide and in eleven top cities, supplemented by key market indicators and fact sheets for over 100 cities.
The German rental housing market is again in remarkably robust shape in the first half of 2026. Despite already high rent levels, asking rents in all city categories under consideration have risen noticeably again within just six months. In the Class A cities and the large and medium-sized cities, asking rents in existing buildings have each risen by 3% since the beginning of the year, while university cities show the highest momentum with an increase of 4%. The Class A cities continue to lead the rental price ranking with an average asking rent of €16.25/m², followed by university cities with €12.75/m². It is striking that the rental price dynamics are increasingly shifting to locations outside the major metropolises. University and medium-sized cities in particular are benefiting from high demand for housing, while supply remains scarce in many places due to declining building completions and persistently high construction costs. This trend is particularly evident in the new construction segment.
"It is noteworthy that the strongest rent dynamics can currently be observed mostly outside the classic top locations. Numerous university and medium-sized cities today have similarly stable fundamentals as the metropolises, but in some cases still benefit from lower rent and purchase price levels. For investors, this results in increasingly attractive opportunities beyond the established A-cities," explains Christoph Meszelinsky, Managing Director and Head of Residential Investment at BNP Paribas Real Estate GmbH.
