Saint-Brais is one of the smallest communes in the Franches-Montagnes, on the eastern edge of the plateau, and most of its buildings are old.
Buying in Saint-Brais means paying more per square metre than almost anywhere in Jura, at CHF 8,900 for a flat. The gap holds even on older stock, so renovation work rarely comes off the asking price the way it does elsewhere. The largest band in Saint-Brais is before 1919, at 38 percent of homes. Buildings of that age were rarely insulated when built, so running costs and the cost of the works belong in the price you offer, not in a list for later. Average size in Saint-Brais is 118 m² across 4.5 rooms. Compare your own property with that figure before you read any price per square metre, because an outsized home rarely sells at the local rate and a small one often beats it.
The market in Saint-Brais is thin, and that cuts both ways. Prices are slow to fall because few sellers are forced, and slow to be confirmed because months can pass without a single comparable sale. The median flat in Saint-Brais comes out at CHF 8,900 per m², a gap of 117 percent against the Jura median. That figure covers every flat sold, whatever the floor, the age of the building or the state of the kitchen.
A gap of 117 percent over the Jura 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. Within the District des Franches-Montagnes district, Saint-Brais lands 93 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.
Per square metre, a flat in Saint-Brais at CHF 8,900 costs more than a house at CHF 3,600. Large houses spread their price across surface nobody pays the full rate for (corridors, cellars, attic space under the eaves). The last twelve months added 3.1 percent in Saint-Brais. Rises of this order usually come from a shortage of listings rather than from a wave of new buyers, and they unwind faster than they build. Over 7 years the median moved from CHF 7,300 to CHF 8,700 per m², a change of +19 percent. That is the market, not your property. A flat renovated in the meantime followed a different curve entirely.
In Saint-Brais the difference between two flats on the same street can run into six figures. Getting your own number, rather than reading the commune median, is what makes that difference visible before you set a price.
