We identify bespoke investment options for investors inside and outside Germany, and conceptualize investment vehicles to suit specific requirements. Since 2005, this has included attractive property special funds that we initiate and manage from our offices in Luxembourg.

For international investors, corporations and property financiers with real estate assets, we can activate the potential of your property portfolios and investments – from strategic analysis and evaluation to management and optimization to marketing and sale.

We realise a total of about 500 residential units per year, with the focus on city center locations in Germany’s metropolitan areas. We cover all aspects from inception and implementation right through to the sale of the development to private investors or organizations.

The unit offers asset management services throughout the entire retail real estate lifecycle. Our clients benefit from the services tailored to their needs, including the positioning of retail properties, the development of usages concepts as well as efforts to secure and boost rent revenues.

For many years we have been among the leading real estate brokers in Germany. In this we act – directly or indirectly – as agents for commercial or residential property of investors and proprietors. Here our focus is on residential property sales for own use or as an investment for individual clients.

We assist investors and property owners throughout the entire life cycle of their residential property or portfolios. Here we add value by increasing rental income, reducing running costs and through carefully considered investment in the property.
