Customer testimonials
Mr. Schreiber
You feel very well advised right from the start, as your professional competence is immediately apparent. Your openness and honesty are exemplary. The way you have always been friendly and sincere with me on the phone is exactly how I imagine a real estate agent should be. This immediately establishes a relationship of trust.
Dr. Schad
With the deal about to be finalized, we would like to thank you very much for your pleasant and friendly support! Thank you very much for handling the sale so smoothly, professionally, and calmly. We felt very well taken care of.
Ms. Hanke
The gentlemen have a good knowledge of the market, and their advice is comprehensive, unhurried, well-planned, and realistic. I would like to thank both gentlemen for their excellent work.
Dr. Deckert
Thank you for the great cooperation.
V.P. - 30. Oktober 2025
We felt very comfortable with them and they are very professional. I would always buy from them again and recommend them to others. I know that not all people are the same, but some of your colleagues could learn from you.
Mr. and Mrs. Arera
After just a few days, you already had several interested parties. This is certainly related to the current market situation. However, we believe that your thorough preparatory work was the basis for your rapid success.
Ms. Tillmann-Vogel
Even two months after the purchase agreement had been signed—i.e., even after the brokerage fee had been paid—Mr. Breuer continued to act as an exemplary mediator for this assignment. Great! Thank you again.

Very professional broker, we always felt well advised. Always available, good assessment of the property and market situation—large local network. Also worth mentioning is the high level of empathy shown in inheritance matters and the personal challenges associated with them. Thank you for the good cooperation.
Mr. and Mrs. Hupe
We would like to thank you for your excellent and conscientious advice and support during the sale of our house.
Ms. Pautsch
From the initial consultation to handing over the keys to the new owners, you provided me with personal, friendly, and expert advice.
Mr. and Mrs. Bosdorf-Schmidt
Through meticulous preparation and a clever sales strategy, you achieved a sale price that significantly exceeded our expectations.
Mr. and Mrs. Hepke - 11. September 2025
Our unreserved recommendation for effective, professional, and competent sales processing.
Mr. and Mrs. Burs
The first viewing appointment was already very thorough, without any time pressure and tailored to our questions. As things progressed, both brokers were always available and no question was too much or left unanswered.
Mr. and Mrs. Trommer
In two years of searching for a house, we saw and experienced a lot. Unfortunately, not much of it was good. That made us feel all the more comfortable in your capable hands right from the start.
Mr. and Mrs. Jost
Looking back, Mr. Breuer not only ensured that we now have excellent new tenants, but also that we were able to significantly improve the structural condition of our building—and all without any unpleasant stress.
Ms. Pramschiefer
I would like to thank you very much for your exceptionally good and kind support.
