How to accurately value a chalet in Chamonix or Saint-Gervais: the complete method

Valuing a chalet in the Mont-Blanc valley is no ordinary exercise. Between the scarcity of land, international buyers, price gaps from one area to another, and sensitivity to high-end features, the Chamonix and Saint-Gervais market follows its own rules. Here is the complete method for carrying out a solid and reliable valuation.

Why valuing an alpine chalet is different

Unlike a standardised city apartment, every chalet is unique: orientation, view, ski access, architecture, general condition, equipment. These variables create considerable differences in value — sometimes 30 to 50% between properties of comparable size — making algorithm-based valuations entirely unsuitable.

In Chamonix, international demand (British, Swiss, American) places pressure on exceptional properties that national databases fail to capture. In Saint-Gervais, the dynamic is different: a French and European clientele, a more accessible market, but values that have risen sharply since 2020.

The 6 pillars of a reliable valuation

1. Precise location

Within Chamonix, the difference in value between a chalet in Les Praz-de-Chamonix and one in the town centre can reach 20%. Argentière, a village popular with expert skiers, has its own market. Les Houches attracts a family clientele with lower values. Each micro-area has its own price grid.

2. Actual living space

The French Loi Carrez surface area measurement does not apply to detached houses. In practice, what matters is the usable living area — excluding unconverted loft space, cellars and basements. Check the planning permission and any works declarations if additional space has been created subsequently.

3. Orientation and view

A chalet facing due south with an unobstructed view of the Mont-Blanc massif can command a premium of 15 to 25% compared to a similar property facing north. The Mont-Blanc view itself is a major selling point for international buyers.

4. General condition and works carried out

A chalet renovated with noble materials (reclaimed wood, stone, copper, spa equipment) is valued well above the cost of the works. Conversely, a chalet requiring renovation must factor in a realistic discount, which can represent 20 to 40% of the price of an equivalent property in good condition.

5. Differentiating features

Heated garage, ski room, hot tub, sauna, wine cellar, professional kitchen: these elements have become selection criteria, not mere options. In the luxury segment (above €1.5M), their absence can be a dealbreaker for some buyers.

6. The comparables method

Valuation by comparison remains the benchmark: 5 to 10 recent transactions on similar properties are identified (same commune, same type, comparable size and condition), adjusted for differences, and a value range is derived. At MOMA Immobilier, we have access to local notarial databases and our own transaction history.

Essential documents for an accurate valuation:

- Title deed and/or notarial deed of acquisition
- Chalet plans (planning permission, works declarations)
- Most recent valid Energy Performance Certificate (EPC)
- Invoices for works carried out (renovation, roofing, insulation, heating)
- Service charges if applicable (semi-detached chalets, residences)
- Most recent property tax notice

At what stage should you have your chalet valued?

A valuation is useful at several points: before putting the property on the market (to set the right price from the outset), as part of an inheritance or gift, during a joint ownership division, or simply to know the current value of your assets. In all cases, a valuation carried out by a local professional is more reliable than an online tool.
