One of Champéry's most longstanding commerces, MDK Immobilier offers a wealth of experience and superior customer service for real estate transactions and investments.
Founded in 1980 in Champéry by Mr. Luis Mendes de Leon, an iconic figure of the village and a passionate lover of the region, MDK Immobilier has developed over the decades into a key player in real estate in the Vallée d’Illiez and the Valais Chablais. Deeply rooted in the heart of the Portes du Soleil area and the Dents-du-Midi massif, the agency has always maintained a close connection with tourism, mountain residences, and the harmonious development of the local built environment, with a strong respect for the territory and its values.
In 2008, the agency was taken over by Mr. Maxime Délez, who has carried on this legacy while bringing a modern, structured, and forward-looking dynamic. Holder of the Swiss Federal Certificate as a real estate broker, Head of Training at USPI Formation, and member of the committee of USPI Valais, he is joined by his associates, Mr. Mathieu Kerneur and Mr. Vincent Rouiller, to expand the company’s activities to Monthey and later to Le Bouveret, while strengthening its historic presence in the valley and the Dents-du-Midi region.
Today, MDK Immobilier relies on a local team of around twenty professionals with in-depth knowledge of the mountain real estate market, second homes, sales to foreign buyers, tourism real estate, taxation, and residential property. The agency offers a comprehensive range of services including sales, purchases, rentals, property management, condominium administration, life annuities, project management, as well as accounting services through its integrated fiduciary department.
Committed to continuous training, rigor, and professional ethics, MDK Immobilier supports private clients, investors, and tourism stakeholders with a human, committed, and sustainable approach, remaining faithful to the spirit of the region it has served for over 45 years.
