Company

Rosenbaum Group is a family-run business. It was founded by the brothers Rouven and Rafael Rosenbaum, who turned their shared vision of a modern, values-driven real estate company into reality.

Our regional focus is Central Germany, and Saxony-Anhalt in particular, where we operate as an active, long-term oriented investor. We acquire residential real estate and enhance our assets both technically and commercially through targeted asset and property management measures. Our portfolio currently comprises around 37 properties with more than 35,000 sq m of lettable space.

What sets us apart is not so much what we do, but how we do it. We give our best to earn the trust of our clients, our tenants and our employees time and again. As a family business, we place great value on dealing with everyone involved in a respectful, fair, open and trustworthy manner. We are convinced that a good working relationship creates more enjoyment at work – and therefore better results.

Our success is built on outstanding market expertise, an uncompromising commitment to the highest quality standards, professional and straightforward execution, and our appetite for innovation. We do not simply watch the shift towards greater sustainability – we help shape it. For example, we have switched all of our properties to renewable electricity. We also work continuously to improve the ecological footprint of our buildings. Ultimately, the future belongs to those who think about tomorrow today – and who act rather than merely talk.

Our business model is based on the acquisition, refurbishment and management of residential properties with development potential. Following acquisition, we refurbish the buildings wherever this is required. Many of the properties we take over have received little attention for years – and this is precisely where we start: we renew the building fabric and reorganise the administrative processes behind the scenes. The result is noticeably better living conditions for our tenants and sustainable value growth for our investors.

In doing so, we pursue an active asset management approach that safeguards the long-term value and growth of our portfolio. We combine structural improvements, targeted communications, tenant events and a responsible letting strategy.

Sustainability and social responsibility are not add-on topics for us; they form part of every investment decision. For every property we assess how it can be developed over the long term in energy and structural terms – and we invest where modernisation delivers lasting impact.

The relationship with the people living in our buildings matters just as much to us. Our letting strategy is geared towards long, stable tenancies – because a good community within a building is the foundation of a portfolio that will still perform decades from now.

We have grown continuously since inception. Through the ongoing acquisition and refurbishment of properties, as well as improved management processes, we have steadily expanded our portfolio and significantly increased the value of our assets.

Renewing and optimising our properties is a central element of our business model. With targeted structural measures and a sustainable letting strategy, we restore the value and standing of buildings that have not seen investment for many years.

We are realising part of this growth together with institutional investors and family offices in our own portfolio companies, which acquire and hold a pre-defined portfolio long-term. We describe how this collaboration is structured under Co-Investing.
