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!
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.
We were completely satisfied with the brokerage services of Mathias Zika. We would choose him again for a sale/purchase at any time. From the property valuation, through the various sales activities, to the closing, notary/land registry, he did an excellent job. The communication was always flawless, we were always informed. The communication channels via WhatsApp (as well as email and phone/mobile) were optimal. We are completely happy, and the price/performance ratio is absolutely right. Furthermore, Mathias Zika is a very likable and trustworthy person. Thank you very much!
I was very satisfied with your service. She was very friendly, professional, and reliable throughout the entire process. My questions were always answered quickly and competently, and I felt well taken care of at all times. I can wholeheartedly recommend you as a broker.
We chose Serkan Düzgün because he seemed very friendly and straightforward, which was confirmed until the end. We were always advised and supported in a friendly and patient manner, which gave us enormous security in this process. His competence in all matters and his support until the end were great! Thank you very much!
I am thrilled with how quickly and professionally Michelle Zimmermann handled the sale of my apartment. Her friendly, competent manner impressed me greatly, I will definitely recommend her.
We were perfectly accompanied and supported by Sven Lott during the sale of our apartment. With great commitment and expertise, he successfully brought the sale to completion. We can recommend Sven Lott in every respect, as he is willing to go the extra mile.
About 5 months ago, we entrusted meinwohntraum AG with the task of selling our house. We wanted nothing to do with it. The creation of the sales documentation, organizing viewings, everything was to be handled by Mr. Amberg. Today, the final signatures were made, and the transfer of ownership has taken place. We were kept informed throughout the entire process about the current status and what the next steps were. Mr. Amberg promptly informed us of any news. When the whole process stalled a bit due to a lack of interested buyers, he showed us possible new activities and implemented them after our approval. We always felt very well taken care of by René Amberg. A big thank you to him and the whole team.
