Just downstream of Porrentruy on the Allaine, Courchavon is a small Ajoie village within a short hop of town.
Courchavon tracks Jura closely, at CHF 4,500 per m² for a flat. Communes in this band are the easiest to value, with enough sales to anchor a price and no local anomaly pulling the figures around. before 1919 accounts for 19 percent of homes in Courchavon, ahead of the other periods without dominating them. A mixed stock widens the price range inside one commune, where two flats of the same size can be a third apart on condition alone. The average home in Courchavon has 4.2 rooms for 106 m². That ratio describes the shape of local demand better than the price does. Many small rooms point to family housing, fewer and larger ones to conversions and new build.
The market in Courchavon 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. CHF 4,500 per m² is the working reference for a flat in Courchavon, 10 percent from Jura. Take it as a starting point. In a commune this size, the spread between the cheapest and the dearest street is often wider than the gap to the canton.
The premium over Jura has a practical effect at resale. Buyers arriving from cheaper communes negotiate hard on condition, because they are already stretched on the price per square metre before they walk in. Within the Porrentruy district, Courchavon lands 25 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.
The 13 percent premium on flats over houses in Courchavon is unusual and needs reading carefully. It normally means the flats sold recently were new or central, while the houses were older and priced mainly on their land. Up 5.3 percent in a year, Courchavon 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. The 7-year record opens at CHF 12,800 and closes at CHF 15,900, +24 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.
Knowing the median in Courchavon gets you halfway. The second half is what separates your property from that median (condition, orientation, outside space, parking, and the works still to be done).
