Mr. Sahli and Mr. Kolp have succeeded in reaching a consensus between the sellers and the buyers. This requires expertise, determination, and transparency. We always felt well informed. This convinced us, and we can only recommend Real Estate further. We look back on a successful purchase completion.








I purchased a property through GCT, Thomas Becker, and subsequently rented it out through them. Thomas Becker and the GCT team have completely convinced me. From the purchase to the renovation and rental, I was able to rely on his extensive experience at any time and always received very valuable and honest assessments. The communication was consistently efficient, straightforward, and at the same time very professional - you can tell that someone is thinking along. I would particularly like to highlight how Thomas Becker and the team work: always fair, solution-oriented, and with a clear focus on a win-win for all parties. This is definitely not a given in the real estate sector! I will be very happy to work with Thomas Becker and the GCT team again on future projects.




Thank you very much for the good cooperation. It worked wonderfully and I am very satisfied. Anytime again!








I would like to sincerely thank Alexander Riesch and his Bündner real estate team for the excellent service throughout the entire sales process of my penthouse apartment in Niederhasli. I was very impressed by their professional and friendly manner. I can highly recommend Mr. Riesch and his team. If I had another property to sell, I would definitely grant the mandate again to Bündner Makler. Thank you very much and continued success and all the best Marcel K.




I can highly recommend Graf & Partner, especially Mr. Niederberger, as a real estate agent. We had the pleasure of working with him as the buying party. Very professional, quick response, and top-notch processing. The service provided is absolutely first-class! I can absolutely recommend Graf & Partner to everyone; it was a great pleasure to view this with you. Thank you once again and best regards, Fam. Pennella




Thank you very much for all the timely, detailed information and the very competent support.




We had excellent experiences with Philipp Niedermann from start to finish and can wholeheartedly recommend him. From our very first meeting, we were convinced by his open, authentic, and exceptionally likeable manner. He is not just a broker doing his job, but a person who genuinely cares about his clients. We particularly appreciated his patience and the ease with which he addressed our many questions. We were anything but experienced in the real estate market and had many questions—probably even some that are completely obvious to a professional. However, Philipp never made us feel like we should already know something. On the contrary: he took the time to explain everything clearly, listened attentively, and consistently followed up with us. We felt taken seriously and well-supported at all times, without ever feeling pressured to make a decision. His honest, straightforward, and human approach made the entire process incredibly pleasant. And there was never a shortage of humor! Dear Philipp, thank you very much for your time, your patience, and your wonderful manner. We greatly appreciated our encounters with you and would reach out to you again at any time. An unreserved recommendation!




Ms. Schillinger was very friendly to us from the very first contact. She advised us extremely competently and kindly, which ultimately led to the purchase of this apartment.
