The German real estate market is regarded as Europe's savest haven for investments. This makes residential and commercial real estate increasingly attractive for national and international investors and for years has been causing declining purchase yields in all usage classes. It is therefore not surprising that, according to KPMG, the volume of real estate transactions in all classes of use rose to a new monthly all-time high of EUR 18 billion in December 2019. Even though the economic climate in the manufacturing sector is currently rather subdued, the construction industry is booming and the credit volumes issued by the banks are rising. But it is not only since the Bundesbank warned of the real estate price spiral that the market must be kept under close scrutiny. What other measures will and can the European Central Bank actually use if the European economy continues to weaken, even though the interest rate has been stuck at 0 % since March 2016? Or what happens if the European Central Bank continues to scale back its bond purchase program and finally starts to raise interest rates? In some German cities there are already signs of a slowdown in rental growth rates or stagnation in rents. What happens if rents and purchase prices drift further apart or business plans that are geared to constantly rising rents and purchase prices do not work out?

Those who deal with these questions at an early stage can better assess and master future challenges. We support you in finding the right answers, for example by optimizing real estate portfolios, repositioning real estate or restructuring real estate loans. Our goal is always to maximize the earning power and value of the property.


We advise investors, insolvency administrators, M&A and restructuring consultants, but also banks and financial companies on all aspects of real estate and its financing. For complex real estate projects, we rely on individual, tailor-made solutions and our many years of expertise in order to preserve value and leverage potential.


As a property investor, you benefit from our many years of experience in management of real estate and financing. We reduce complexity so that you can concentrate on the essentials. Our holistic approach simplifies the process of finding solutions. Based on an individual analysis, we offer you a one-stop service. This includes communication with your bank up to the complete turnaround of your real estate investment.

Insolvency Administrators

Our extensive expertise with non-performing loans and real estate in insolvency minimizes your time and effort. In doing so, we maximise the realisation proceeds in the liquidation of insolvent real estate investments. We create tailor-made concepts, implement them and thus help to settle insolvencies faster and with better realisation proceeds. Our team looks back on many years of successful cooperation with insolvency administrators and understands your specific requirements.

M&A and Restructuring Advisors

Before and during many M&A transactions for business operations, the question arises whether to sell with or without business real estate. With a focus on the real estate, but in close cooperation with the M&A advisors, we support you strategically and operationally in your decision-making process. The processes are managed in parallel to the sale of the company in order to open up additional options for action and increase the probability of the transaction.

Banks & Financial Institutions

We always keep the goal of maximum repayment of real estate secured loans in mind when advising banks and financial companies on the management of sub-performing and non-performing (NPL) loans and loan portfolios. We are the link between investors and financiers, promoting effective and targeted communication. We increase the repayment rate by implementing value creation of the financed non-performing property in a target-oriented manner.
