Ms. Lehner coached and supported me competently, friendly, and personally throughout the entire sales process. Starting with the appraisal of the apartment, through individual advice on the appropriate sales strategy, to valuable little daily tips, she provided me with professional advice and accompanied me on the sales journey. A heartfelt thank you for the great work, Ms. Lehner!
From the evaluation to the contract signing, everything was excellently organized. We were particularly impressed by his market knowledge in the Basel region. You can immediately feel the experience and passion for real estate. Mr. Albert works efficiently, discreetly, and with a clear plan.
Very satisfactory service, good and competent advice. Smooth handling of the sale.
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.
I received very good advice – competent, transparent, and reliable. The valuation of my property as well as the agreed sale price were adhered to exactly. I was particularly impressed by the great effort of the team throughout the entire sales process. I can definitely recommend the company without reservation!
Very friendly and competent. Great, as viewings can also be done in the evening and on weekends. Really very dedicated. Also always reachable via WhatsApp if you have a question.
Livio Ackermann is a very competent real estate expert with a solid expertise and a good demeanor. We were able to sell our property in a short time and at a good price. The collaboration with Mr. Ackermann was excellent at all times. I can recommend him without reservation.
