The collaboration with Ms. Bettina Schwerzler was very pleasant and professional from the beginning to the completion of the sale. She competently, transparently, and always kindly guided me through the entire process. I particularly appreciated her structured working method, her good availability, and her commitment. I felt well cared for and taken seriously at all times. I can wholeheartedly recommend Ms. Schwerzler and sincerely thank her for the successful collaboration.
We would like to sincerely thank Mr. Timur Mazlar from Premium Homes for the excellent support during the sale of our property. From the very first meeting, Mr. Mazlar impressed us with his friendly, competent, and professional manner. His transparent communication, reliability, and always well-groomed and representative appearance are particularly noteworthy. You can immediately tell that he practices his profession with passion. His professionalism and availability are also consistently highlighted positively in other customer reviews. Our sale was anything but easy and required patience and perseverance. However, Mr. Mazlar provided a realistic assessment of the market situation from the very beginning and predicted that the sale could be successfully completed within a year. This is exactly what happened. Throughout the entire process, we felt well advised and always well informed. Thanks to his commitment, market knowledge, and professional support, we were able to successfully sell our property. We can wholeheartedly recommend Mr. Timur Mazlar and thus also Premium Homes, and we would work with him again at any time. Thank you for the excellent support!
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.
In October of last year, we purchased an apartment and were accompanied throughout the entire process by Marianne Gubler. Communication was always absolutely top-notch, we could always rely on her advice, and she showed a lot of patience and professionalism. This also applies to dealing with other involved parties (my bank, various offices, etc.): Ms. Gubler always communicated excellently and arranged everything necessary without any issues. In short: Anyone who has Marianne Gubler by their side for such a large and important transaction can sleep soundly.
I can unreservedly recommend this real estate agent. From the first conversation to the notarization, the sale of our house was accompanied in an extremely professional, competent, and committed manner. I particularly appreciated the transparent communication, the realistic market assessment, and the reliable availability at all times. Thanks to the excellent marketing and negotiation skills, our house was successfully sold under very good conditions. The entire sales process was uncomplicated and pleasant for us. Thank you very much for the excellent support and the always trustworthy collaboration.
We sold out apartment with newprop. Extremely competent and we managed to get offers under 6 weeks. Great photos and marketing material.
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!
We chose Serkan Düzgün because he seemed very friendly and straightforward, which was confirmed until the end.
