State capital in the Rhine-Main region, stable prices, tight housing market, and rent control. We have compiled the official figures for Wiesbaden and honestly calculate a rented apartment.

Wiesbaden is more than just the administrative center of Hesse. For investors, the city offers a stable environment with high purchasing power and a vacancy rate that is among the lowest in Germany. But quality has its price: the purchase prices are high, and the rent control slows down the yield.

Here you will find the official figures, the development of population and demand, the rules for landlords, and an honest calculation for a sample apartment.

02Population and demand

Wiesbaden is one of the few large cities in Germany that will continue to grow according to forecasts. The Hessen Agentur expects an increase to over 305,000 inhabitants by 2040.

The housing market is extremely tight. The vacancy rate of 1.7% determined by the state of Hesse is one of the lowest in the country. This means that a rented apartment is almost never empty. For investors, this ensures a very high level of security in the rental income.

03Economy and labor market

As the state capital, Wiesbaden is a stable location. Public administration, insurance companies (such as R+V), and many service companies ensure a high number of social insurance employees. The purchasing power of the population is significantly higher than the national average.

04Mieten, Kaufpreise und Mietrendite

The stability of Wiesbaden is reflected in the prices. Used condominiums cost an average of around €4,000/sqm. In good locations and with newer buildings, significantly higher prices are achieved.

Rents follow the prices but are limited by the rent index. The 2025 rent index shows a median of approx. €10.30/sqm.
