I bought my house through Jacqueline von Ow from onesta and am more than satisfied with the entire support. Throughout the entire purchasing process, I was accompanied by Jacqueline with great professionalism, personal commitment, and a lot of passion. She always had an open ear for my concerns and was always competent, reliable, and helpful when I had questions. I was particularly impressed by her honest, open, and friendly manner as well as the cooperative and trusting collaboration. I felt well taken care of and advised at all times during the entire purchasing process. If I ever decide to sell my house again, Jacqueline and onesta would undoubtedly be my first choice. A heartfelt thank you for the excellent support, the great commitment, and the overall pleasant collaboration.




I had a very good experience with Cosmos Values AG and the agile and goal-oriented Ms. Rena Wisler. Everything was very professional and perfect, which led to a good, fair sales result / sale price. The support for the buyers was also exemplary and of high quality. The entire formal sales process from the notarial purchase contract to the transfer of ownership was perfectly and stress-free organized. By the way: I found Ms. Wisler through a recommendation from enthusiastic acquaintances who previously used the services of Cosmos Values for the sale of real estate.




Mr. Plüer is very professional and competent. He was very flexible and always available to address our concerns. He always took the time to answer all our questions in detail. Moreover, he facilitated excellent communication between us and the sellers, which significantly eased the entire process. We felt well cared for and advised throughout the entire procedure.




We were very satisfied with Andreas Graf and his support during the sale of our property. We particularly appreciated his willingness to help and his very good availability. He was always there for us with questions and took the time to explain and clarify everything understandably. At the same time, he actively took care of driving the sale forward, which we especially appreciated. We felt very well accompanied and supported throughout the entire sales process. We can recommend him with a clear conscience. Thank you very much, Andreas!




As legal advisors to friends who had engaged the boutique real estate agency Neves Stierle & Horn for the sale of a larger special property, we have witnessed how professionally and amiably the trio has carried out their assignment. Convinced of the qualities of the three ladies, we engaged them for the sale of our own property. They executed the assignment in a short time to our complete satisfaction, both professionally and amiably. We felt well taken care of and supported at every stage of the sale. The buyers also greatly appreciated the collaboration with our agents. The three women accompanied both us as clients and the buyers throughout the entire process with dedication and expertise in a very pleasant manner. We can only highly recommend this team and would engage them again at any time if needed.




I would like to sincerely thank Mr. Lombardi for the excellent support in selling my old town house. From the very first contact, he was always competent and professional, very dedicated, and truly took the time for my wishes. I was particularly impressed by his transparent communication throughout the entire process. Thanks to his expertise and care, he introduced me to a perfect buyer for my old town house, who also made the purchase. I can only recommend Mr. Lombardi from BILO GmbH. Thank you once again.




The collaboration with Cornelia Fischbacher was very pleasant. She is very competent, reliable, and supported us excellently in all matters. Cornelia Fischbacher also explained everything very clearly. It was very relaxed from the beginning to the conclusion.




The collaboration was contractually regulated at the beginning, the initial situation and the conditions were clearly clarified. The property was advertised locally and on various platforms. If there was interest, the property was shown, if necessary, multiple times. Due to the solid knowledge from the banking sector and land registry, questions from potential buyers could be competently clarified. The flow of information was always present, and the collaboration was very pleasant. As a seller, I was supported and accompanied from the assignment to the signing at the land registry office. I would give the assignment to Ernst Zwingli again, thank you very much!
