Current real estate listings for sale in Düsseldorf, Mettmann, Ratingen, and Velbert

Mr. Schönig

This is partly due to the professional attitude with which you handle "smaller" brokerage assignments, such as our apartment sale undoubtedly was, with the same commitment and conscientiousness that one would expect for large transactions. The intensive discussion/consultation on alternative options, which was necessary due to a special family situation, also demonstrated your extraordinary commitment, but also your in-depth expertise, which goes far beyond purely real estate-related issues.

I am very satisfied and grateful with the sale of my parents' house, during which I was supported by Mr. Kartheuser's team, especially Ms. Dickmann. As I live far away from the property that was sold, it would have been difficult for me to find buyers, etc. Everything was taken care of, my wishes were respected and fulfilled. My questions were answered quickly and competently. Thank you very much for everything.

Mr. and Mrs. Gehlen

We sold our house through Kartheuser Immobilien in Ratingen and felt very well looked after there right from the start. The excellent support provided by Mr. Marcus Breuer deserves special mention. We couldn't have found a better real estate agent. He always gave us professional advice and support and took care of all the formalities surrounding the sale of our property in a highly professional and friendly manner. From the initial contact to the completion of the sale and subsequent handover of the house, everything went smoothly. Thank you very much! We would like to take this opportunity to once again express our sincere gratitude to Mr. Breuer for the excellent cooperation and wish him all the best for the future and continued success. We can definitely recommend Kartheuser Immobilien and especially Mr. Breuer!
