Data-driven investment analysis of the German rental market

Unlocking the best performing single-family rental housing in Germany


Germany has strong demand for housing in the “Top 7” cities

Within Europe, Germany has some of the highest demand for rental housing in its “Top 7” cities which include Hamburg, Dusseldorf, Cologne, Frankfurt, Stuttgart, Berlin and Munich. Driving this demand is strong population growth, high volumes of renters and a preference for smaller household sizes:

Strong population growth

Population growth in Top 7 cities vs. rest of Germany

High % of rents

Distribution between owners and renters

Reduction in household sizes

Percent of households comprising 1 or 2 people

GDP and employment growth indicate significant opportunity

As an example, we’ve identified that Cologne’s GDP and employment growth has steadily outperformed the German average. Between 2005 and 2020, Cologne’s GDP grew at a compound annual growth rate (CAGR) of 1.52% compared to the German average, which stood at 1.04%.

During the same period, Cologne’s employment grew at a rate of 1.47%, versus the German average of 0.88%. These are indicators that support a capital and rent growth opportunity, not only in the Cologne market, but also in its surrounding areas. In many areas of Germany, high rental price growth continues to outstrip supply and this growth isn’t limited to its cities.

Cologne and Rhein-Erft-Kris
are prime rental districts

Taking Cologne again – where rentals make up 71.9% of housing – and one of its neighbouring commuter districts, Rhein-Erft-Kris, as an example: the growing demand for rental properties within these two districts has resulted in rental price growth of 12% over the past five years and a significant drop in the average time it takes for an apartment to rent, falling from around 10 weeks to around five weeks in Rhein-Erft-Kreis, and from around six weeks to around three weeks in Cologne. With population and disposable incomes forecast to grow annually by 1.2% and 1.0% respectively over the next 10 years, demand and rental prices will continue to drive upwards in both regions.
