Several factors influence real estate prices in Saint Gervais Les Bains, particularly its attractiveness as a ski resort and summer destination. The proximity to the Mont Blanc massif significantly raises property values, with luxury chalets often selling for upwards of €8,000 per square meter during peak seasons. Seasonal demand plays a crucial role; for instance, prices can soar by nearly 20% during winter months when tourists flock to the ski slopes, which offer over 400 kilometers of ski runs. Additionally, the local economy, driven by tourism, affects real estate prices; a report indicated that rental yields in the area can reach 6-8% for short-term holiday lets. Infrastructure developments, such as improvements to the transport network and local amenities, also impact market values, seen in the rise of new apartment complexes being listed at approximately €5,000 per square meter due to enhanced accessibility. The area's remaining natural beauty and conservation regulations further limit available land, contributing to a consistent upward pressure on prices.
