At the end of Lake Geneva at the mouth of the Rhône, Port-Valais combines the lakeside resort of Le Bouveret with the hillsides of Les Évouettes.
Flats in Port-Valais change hands around CHF 6,500 per m², well above what the rest of Valais pays. The premium is priced into the land more than into the building, which is why two similar houses here can be valued very differently. A gap of 18 percent over the Valais median is not statistical noise. It measures what buyers accept to pay for the location itself, and it holds through the cycle instead of appearing in one strong year.
Out of 67 communes measured in Valais, Port-Valais sits at position 10. The communes immediately above and below are the ones a buyer will actually compare against, far more than the cantonal average. Up 3.2 percent in a year, Port-Valais has been priced by whoever was willing to pay most for a small number of properties. In a commune with few sales, that is exactly how a median gets moved.
Within the Monthey district, Port-Valais lands 5 percent from the local median. A cantonal average mixes city and countryside, so it flatters some communes and penalises others. The district figure removes most of that distortion. No single period defines Port-Valais, though after 2015 leads with 14 percent. That mix works in a buyer's favour, since you can choose between period character and low running costs without leaving the commune. Average size in Port-Valais is 92 m² across 3.5 rooms. Compare your own property with that figure before you read any price per square metre: an outsized home rarely sells at the local rate, and a small one often beats it.
Half the flats sold in Port-Valais went above CHF 6,500 per m² and half below, which puts the commune 18 percent from the Valais median. One exceptional sale barely moves a median, and that is why we use it instead of an average. The 25-year record opens at CHF 3,700 and closes at CHF 8,000, +116 percent apart. Use it to sanity-check an estimate rather than to project forward, since nothing in the series promises the next decade repeats it.
Enough properties change hands in Port-Valais each year to keep the price data steady. Estimates land in a narrower range here, and a valuation can lean on recent comparable sales instead of falling back on the cantonal average. The figures above describe Port-Valais, not your property. At this end of the market the distance between the two is where the negotiation happens, so start from a valuation that takes your own characteristics as its input.

Count on roughly CHF 6,600 per m² for a house in Port-Valais. That rate applies to habitable surface, which leaves out the garage, the cellar and any unconverted attic, all of which add value but never at the same rate.
The dominant band in Port-Valais is after 2015, which covers 14 percent of homes. Average size runs to 3.5 rooms, so the commune is built mainly for households rather than for single occupants or short stays.
