The German real estate market is regarded as Europe’s safe haven for investments. This makes residential and commercial real estate increasingly attractive for national and international investors and causes declining yields in all real estate investment classes. While the commercial housing investment market achieved the third-best result in recent years, transaction volumes on the German commercial real estate market rose to an all-time high in 2018. The construction industry is booming and the volume of real estate backed loans issued by banks is rising. But it is not only since the Bundesbank has warned against the real estate price spiral that it is important to keep a close eye on the market. What happens if the European Central Bank continues to reduce its bond purchase programme and finally starts to raise base interest rates? The recent turbulence on the global stock markets was caused by concerns about rising interest rates. What happens if rental and purchase prices drift further apart?

If you as a real estate investor or bank do not deal with these questions in time, you may sooner or later get into difficulties. We support you in finding the right answers, for example by repositioning properties, aligning the interests of the bank and the owner or restructuring loans (NPL). We always aim to maximise the profitability and value of the property.


As an owner-managed and customer-oriented company, we advise banks, financial institutions, insolvency administrators and property owners on all aspects of real estate and its financing. In the field of distressed real estate and non-performing loans, we rely on years of experience to find individual, tailor-made solutions to preserve existing alongside raise potential value.

Banks & Financial Institutions
