Very friendly and professional support From the very first contact, we felt very well taken care of. The agent was always friendly, competent, and helpful. From the creation of the listing to the photos and viewings, all the way to the handling of the contract, everything was organized professionally and accompanied reliably. Our house was sold at the desired price. We sincerely thank you for the excellent support and can recommend him at any time.
I found Ms. Aregger to be very competent. I was always informed about every step. I would involve her again immediately.
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.
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!
We experienced our home sale with Mr. Woodtli as very pleasant and greatly appreciated his professionalism, knowledge, experience, transparency, and friendliness. We always felt competently accompanied. We have already recommended him and the company Hama with pleasure.
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!!!
The sale of our house in Rheinfelden went smoothly and quickly. The team was very flexible and helpful.
We were able to purchase our new home through RF AG. The entire buying process went excellently. From the initial contact, through the viewings, the subsequent answering of questions, to the signing of the purchase contract and handover of the property. The sales documents were very detailed and transparent. We were always served competently and quickly. We would work with RF AG again at any time and can warmly recommend this company (as buyers or sellers). Thank you!
