Ms. Tröndle was recommended to us by a relative who knew her through business connections as a second opinion, since we already had an offer for the sale of the apartment at that time. Ms. Tröndle made her first visit in April 2025, and it was immediately clear to us that we would proceed with her for the further process. Crucial was that she took our concern about finding a suitable apartment after the sale seriously and offered us her assistance, unlike the competitor. She implemented this immediately, and we were able to rent an apartment for June 2026 through her mediation as early as July 2025, even though the marketing of our apartment only took place in the fall. This was a great relief for us and meant even more trust in Ms. Tröndle. During the sales process, Ms. Tröndle always provided us with good advice and support with her suggestions and recommendations. The sale of the apartment was a great success, and we are very satisfied with it. We are happy to recommend Ms. Tröndle due to her high level of expertise, reliability, and friendliness.
Reliable, - a man of his word. For excellent collaboration!
Top service from the evaluation to the sale. Very good market knowledge and transparent communication. The sale was handled efficiently and professionally.
From the first conversation to the notarial certification, I felt excellently supported at all times. My real estate agent dedicated herself with exceptional commitment, great expertise, and a lot of passion to the sale of my apartment. I was particularly impressed by her transparent communication, the realistic assessment of the market, and her tireless efforts to find the best solution for all parties involved. I never felt like just a number – rather, I was personally accompanied, competently advised, and promptly informed about every step. Thanks to her professional marketing, her negotiation skills, and her great commitment, my apartment was successfully sold. Especially during a personally challenging phase of my life, it was reassuring to have such a reliable and trustworthy partner by my side. I can recommend her without reservation and sincerely thank her for her extraordinary efforts. Anyone looking for a dedicated, honest, and competent real estate agent is in the best hands with her.
Exceptional broker performance with foresight and passion ;) I am extremely grateful for the excellent work of this broker, who introduced me to an extraordinarily potential-rich property – consisting of a former pigsty with a residential house. From the very beginning, he impressed with the highest professionalism, solid expertise, and a remarkable sense for special properties with development opportunities. What made this mediation special was his vision beyond the current state: He not only recognized the charm and substance of the property but also managed to clearly and realistically demonstrate its future potential. His advice was always honest, transparent, and competent – free from empty promises, but characterized by genuine conviction and commitment. The entire process was smooth, reliable, and pleasant. Questions were always answered promptly and in detail, viewings were professionally prepared and accompanied. You can feel that someone with a passion for real estate is working here and takes the needs of his clients seriously.

I am extremely satisfied with the work of ErfolgsMandate GmbH. Ms. Billeter handled the sale of my property absolutely professionally and with great commitment. I was particularly impressed by the all-around service: From the first-class, professional photos that showcased the apartment perfectly, to the organization of additional services such as the replacement of the locking cylinders and new keys for the apartment and mailbox - everything was done smoothly. Thanks to her expertise, the property was sold at a top price. Anyone looking for a competent, reliable, and thoughtful real estate expert is in the best hands with Ms. Billeter. Thank you very much for the great support!
