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.

We sold our condominium as part of an inheritance division and chose the real estate agency Cosmos Values AG in Zollikon. We were thrilled with the professional and transparent handling from A to Z and are particularly pleased with the good sale proceeds. The sale was processed quickly. Even after the sale, we received excellent support in legal and tax matters, which was not a given for us. We can only recommend Ms. Wisler.

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!
