Listed properties are among the last remaining legal opportunities for effective tax savings in Germany. The high depreciation possibilities lead to above-average returns compared to other capital investments.
The renovation of listed properties is supported by attractive KfW programs. These subsidies significantly reduce your financing costs and noticeably improve the profitability of the investment.
Listed properties are unique and have a special architectural charm - a factor that makes them particularly sought-after on the market. As a result, they generally show an above-average increase in value.
The combination of tax depreciation and state subsidies creates a solid basis for stable and high returns. The economic profitability of these investments is therefore particularly predictable.
As tangible assets, real estate offers natural protection against inflation. Historically, they are among the most stable forms of investment with continuous value growth.
A large part of the purchase price can be financed by bank loans. Particularly in the case of rented listed properties, this debt financing lever significantly increases the return on equity - an advantage that is often not possible with other forms of investment.
We are committed networkers and maintain strategic partnerships with trusted experts in order to offer our clients comprehensive advice on all aspects of real estate.
Our network provides access to professionals in the fields of financing, energy-efficient renovation, architecture, interior design, relocation, and much more—both locally and internationally.
