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.
In a short time, we were able to sell our house through Marie. We appreciated her efficiency and availability. And the collaboration was friendly. We sincerely thank her.
Tabea went above and beyond to help with the sale of my property, it was not easy for me to deal with the local issues related to the house as I am in the UK now, but Tabea stepped in, and assisted me, even with things not directly related to the sale. Thanks again Tabea!!!
Mr. Kalberer is very professional, knows the local market conditions very well, the sales dossier is excellently prepared, and he is very flexible with viewing appointments. I can highly recommend Mr. Kalberer.
The sale of our house in Rheinfelden went smoothly and quickly. The team was very flexible and helpful.
Rena Wisler from Cosmo Values AG has been of extraordinary help for us when buying our house. As foreigners, we did not have a good overview of the purchasing process in Switzerland but she supported us at every step. From visiting the property and getting to an agreement with the previous owners to taking care of the contract and notary appointments, Rena has made the whole experience rather straightforward and significantly reduced the overall stress. She is really approachable, attentive and supportive. 100% recommended!
I can highly recommend Lukas Minder from Minder Immobilien. Very professional, transparent, and dedicated support from the first conversation to the handover of keys. The marketing was well thought out and targeted, and communication was always quick and reliable. Thanks to his negotiation skills, an excellent result was achieved. Thank you for the great collaboration!
We would like to sincerely thank Mr. Salih Küçük for the excellent support in selling our house. From the very beginning, he was extremely friendly, professional, and always available for our concerns. With his open ear, competent advice, and great commitment, he accompanied us throughout the entire sales process in the best possible way. We always felt well taken care of and could fully rely on his expertise. The house sale was therefore pleasant, quick, and successful. We can wholeheartedly recommend Mr. Küçük and would choose to work with him again at any time. Thank you very much for the excellent care!
