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!
As an inheritance community, we were extremely satisfied with the work of Renate Büttler and Casaventa. From the very beginning, she provided us with competent advice and showed us how we could optimally prepare the property for sale. The BKP cost estimate she created for potential buyers was particularly valuable. This provided them with a realistic basis for the upcoming investments, and the financing clarifications with the banks could be significantly expedited. The collaboration with Renate Büttler was always pleasant, trustworthy, and transparent. We were regularly informed, our questions were answered quickly and understandably, and we felt very well supported throughout the entire sales process. Our property was by no means an easy object to sell. Renate Büttler explained to us at the beginning that she had been able to sell every property within six months so far – and indeed, she managed to sell it after just five months. We found Renate Büttler to be an exceptionally accommodating, dedicated, and highly skilled real estate agent. We can wholeheartedly recommend her and Casaventa and would reach out to them again at any time.
Mr. Caranchi supported me very professionally in the sale of the apartment. I greatly appreciated working with him, open, communicative, and very reliable. I would choose him again for a sale at any time. For these reasons, definitely 5 stars.
I was accompanied by Edoardo Köppel and Köppel-Legal AG during the sale of my 2.5-room apartment on Rossweid in Sins and was very satisfied with the collaboration. The initial assessment of the apartment and the realistically achievable selling price was understandable, honest, and well-founded. The professional preparation of the sales documents and especially the successful photos made a very good impression. Throughout the entire sales process, Mr. Köppel was reliably reachable, responded quickly, and kept me informed transparently about viewings, feedback, and the next steps. I particularly appreciated his calm and solution-oriented approach with sometimes demanding interested parties, who initially backed out, later agreed again, or tried to significantly lower the price. Mr. Köppel conducted the negotiations consistently and with the necessary sensitivity. Despite these challenges, the apartment was sold at a higher price and without unnecessary complications. I felt well taken care of at all times and can recommend Edoardo Köppel and Köppel-Legal AG without reservation.
Mr. Schlösser was recommended to me as a real estate agent. From the first conversation to the notarization, I was always supported and well advised by Mr. Schlösser. In case of uncertainties, he always provided me with excellent support and helped me find a good solution. I can therefore highly recommend Mr. Schlösser for your real estate sales, with his friendly and well-groomed appearance and his professional support. Erich Aeberhard
Very pleasant and professional contact. The company Predio - Real Estate sold my property to my complete satisfaction. In the event of a future sale, I would always consider Predio - Real Estate again. In this sense, I can highly recommend Predio Immobilien GmbH.
The communication was extremely straightforward and the purchase went quickly and without delays. Ms. O'Neill coordinated everything promptly and we could rely on her with a clear conscience.
Very pleasant, competent, and goal-oriented support from the first contact conversation, through the presentation of the single-family home, the viewings, until the completion of the transaction.
