We sold our apartment with the support of Mr. Morris Kathrein from Property Partners and were very satisfied with the entire collaboration. During the first conversation, Mr. Kathrein explained the sales process transparently, understandably, and professionally. His competent demeanor convinced us from the very beginning – and this positive impression was confirmed throughout the entire sale. The sales documentation was prepared in a high-quality and very appealing manner. Subsequently, the property was published on the relevant platforms and additionally targeted interested parties from the extensive network of Swiss Property Partners. This allowed numerous potential buyers to be reached. Mr. Kathrein organized and conducted all viewings personally and individually with each interested party. As sellers, we had practically no effort involved. The further processing also went smoothly and efficiently: from the reservation to the drafting of the purchase contract to the notary appointment, the entire process was competently coordinated and accompanied by Mr. Kathrein. We found Mr. Kathrein to be an extremely dedicated, reliable, and very professional contact person who was always available for questions. We can wholeheartedly and without reservation recommend Swiss Property Partners to both sellers and buyers.
