Your real estate agent for Düsseldorf - Friedrichstadt – Sale & valuation of Kartheuser Immobilien

This year, we had the opportunity to sponsor the Pig Run for the first time, and we are delighted to have been part of this special event. Despite the rainy weather, more than 700 participants took to the starting line. The positive atmosphere, the great dedication, and the high motivation of everyone involved impressively demonstrated the significance of the Schweinelauf in the region. For many years, the Schweinelauf has stood for community, solidarity, and social engagement. Together with the Lions Club, numerous volunteers, sponsors, and supporters, we once again organized an event that brings people together while supporting important social projects. We are particularly pleased with the outcome of the event: a total of around 20,000 euros was raised for social institutions and projects in the region. Among those benefiting from this support are the Wülfrath Food Bank, the Youth Red Cross, the WIR-Haus, the DRK Farbenfroh Kindergarten, and the Lions Hilfswerk Mettmann-Wülfrath. We would like to extend our heartfelt thanks to all the organizers, volunteers, runners, and spectators who contributed to the success of the 19th Schweinelauf. We are proud to have supported this event and are already looking forward to next year’s anniversary edition—the 20th Schweinelauf.

We at Kartheuser Immobilien are proud to present our brand new magazine. Here you can take a look behind the scenes of our daily work as real estate agents.

This year, we are continuing our commitment: For every successful placement, we plant new trees. Part of our team was on-site in Ratingen and actively supported the reforestation effort. Everyone should plant at least one tree in their lifetime. As a company that places great value on sustainability and environmental awareness, we want to actively do our part. Because quality, experience, satisfied customers—and a good feeling—are inseparable for us. This applies not only to our daily work but also to environmental and climate protection. 👉 That’s why, together with our partner PLANT-MY-TREE®, we plant a new tree for every contract we broker.

The initial property description is often the moment when “We’re thinking about selling” turns into a concrete plan. In North Rhine-Westphalia in particular, it’s worth doing a quick mandatory check before placing an ad in 2026: After all, the energy performance certificate and requirements under the Building Energy Act (GEG) affect not only the eventual property viewing but also the real estate listing itself. By handling this properly, you can avoid unnecessary delays, follow-up inquiries, and legal risks.

The team at Kartheuser Immobilien recently gathered at the Ratingen office to refresh and expand their knowledge of first aid. The instructor from the German Red Cross led the session with great expertise and a practical approach. 🩺 Practical, informative, and hands-on Important first aid procedures were reviewed and practiced hands-on—from the recovery position to CPR and the proper response in emergency situations. The focus was not only on theory but, above all, on active participation and the confident application of these procedures.
