Thanks to the professional guidance and expertise, our semi-detached house was sold in a short time for the best possible price. Carine Keller has very good knowledge of current real estate prices and the situation of supply and demand in the local real estate market. Her assessment of the property was market-conform, and the professionally designed sales documentation, along with placing the property on the right platforms, contributed to the quick completion of the sale. We were very well accompanied and supported by Carine Keller in this sales process. She always handled and answered all our concerns, questions, etc. very promptly and competently. The collaboration with Carine Keller is very pleasant. We can highly recommend Ms. Keller.

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.

Urs Kälin informed us (laypersons) in detail about the entire sales process, then carried it out step by step, while we were regularly updated. The sales documents were very detailed, and a broad but selective range of potential buyers was contacted for an initial round of offers. In the second round, it became critical, as the first interest rate change after many years was announced, and some bidders withdrew. The most attractive of the remaining offers had a tight deadline, which, just a few days before the summer holidays and with a somewhat customer-unfriendly land registry office regarding appointments (9 co-owners), became a balancing act for U. Kälin, which he mastered brilliantly thanks to good relationships and negotiation skills. The seller's side was extremely satisfied with the work of UK as well as the result.

We were very satisfied with Carmen Tröndle. With her experience and her open, personal manner, she built trust with us and the potential buyers and accompanied us very well throughout the entire house sale. The collaboration was very pleasant and straightforward - she proved this already when choosing from ten possible agents. We are pleased with the successful conclusion. We highly recommend her.

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.
