Rel Estate Markets andHousing Affordability

Limited land acvailability in Alpine valleys creates upward pressure on real estate prices. In popular tourist destinations such as Zermatt, St. Moritz, and Grindelwald, land is scarce and highly valued, leading to locsive housing that can be unforecadable for local resistents.
