We are extremely satisfied with the sale of our house in Rorschacherberg through MyWinvest GmbH. From the initial property valuation to the professional marketing and the successful completion of the sale, we were competently, personally, and reliably supported. We were particularly impressed by the very good accessibility, the transparent communication, and the great commitment of Michael Diethelm and his team. The unique features of our property, especially the attractive location in Rorschacherberg with a view of Lake Constance, were excellently presented in the sales listing and during the viewings. Thanks to the professional property marketing, the targeted selection of suitable buyers, and the well-founded advice, our house was successfully sold. We felt well cared for and well informed throughout the entire sales process. Anyone looking for a reliable real estate agent for selling a house in Rorschacherberg, St. Gallen, or the entire Eastern Switzerland is in the best hands with MyWinvest GmbH. We can wholeheartedly recommend MyWinvest GmbH.

Very discreet and professional handling – just how one wishes for a real estate sale. Thank you very much for your excellent work. We were very satisfied and can only recommend you further. The MyWinvest property management, together with Immo Generation AG, took over the sale of our single-family home in Amriswil and already found a suitable buyer under the table in a short time. The communication was personal, honest, and reliable at all times. We particularly appreciated the calm, serious approach and the good network in Eastern Switzerland. We felt very well supported throughout the entire sales process and can absolutely recommend MyWinvest property management as well as Immo Generation AG for real estate sales. A big compliment to Mr. Diethelm and his team, who were also always reachable and helped us promptly.

A real estate agency that truly thinks along. I found the collaboration with MyWinvest Property Management to be very pleasant, honest, and professional. From the first contact to the conclusion, I felt that this was not just a transaction being processed, but that there was a genuine concern for the customer and the property. I was particularly impressed by the clear communication, good accessibility, and serious support throughout the entire sales process. The collaboration with Immo Generation AG also left a very competent impression. For me, a clear recommendation for anyone looking to sell their property and who values trust, experience, and personal guidance.

You feel taken seriously, well accompanied, and well informed at all times. This is exactly how one envisions a strong real estate agency. I would work with MyWinvest again at any time and can only recommend them.
