Excellent customer service. Mr. Jaun is always friendly and professional. I can only recommend him and his company.
The collaboration with Andreas was wonderful from A to Z. We greatly appreciated the open and efficient exchange. We also had the pleasure of getting to know Andreas, a dedicated and knowledgeable person who practices his craft with passion. We hope to maintain contact - perhaps over a glass of Heida - :). We can warmly recommend Andreas. Best regards & see you soon
Ralf and Ernst are a very good team. They advised and supported us well from the very beginning. Top service regarding taxes, land registry office, forms... They were a great help. Thank you Zwerit 🤗 E.T.
Mr. Wiesner acts like an experienced project manager: proactive, solution-oriented, quick, and competent. Mr. Wiesner was usually one step ahead of all parties involved and processed/answered/forwarded the necessary information or documents promptly.
Mr. Imeroski was a great help in obtaining the information we needed for our purchase and ensured that the entire transaction went smoothly.
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!
