A border village facing the French town of Delle, Boncourt lies where the Allaine leaves Switzerland and where the A16 Transjurane motorway crosses into France.
At CHF 2,800 per m² for a flat, Boncourt is one of the cheaper places to buy in Jura. Lower entry prices normally come with a longer commute or an older building, and one of the two usually explains the discount. A gap of 32 percent against Jura means the same budget buys noticeably more surface here. It also means resale leans on demand spilling over from the pricier communes next door, which comes and goes with the cycle. Out of 49 communes measured in Jura, Boncourt sits at position 44. The communes immediately above and below are the ones a buyer will actually compare against, far more than the cantonal average.
A house in Boncourt is valued around CHF 3,400 per m² against CHF 2,800 for a flat, a gap of 21 percent. Land is what separates the two figures, and the scarcer the building plots, the wider that gap runs. Flat prices in Boncourt are up 3.5 percent over twelve months. One year is a short window, so measure it against the longer trajectory before you read it as a change of direction.
Within the Porrentruy district, Boncourt lands 22 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. before 1919 accounts for 16 percent of homes in Boncourt, 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 Boncourt has 4.8 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 median flat in Boncourt comes out at CHF 2,800 per m², a gap of 32 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. From CHF 4,500 to CHF 7,200 per square metre in 25 years, +60 percent in all. The path was not a straight line, and the flat or falling stretches inside it are precisely what a long average hides.
Enough properties change hands in Boncourt 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. Lower prices in Boncourt do not make a valuation easier. The spread between properties is often wider here than in an expensive commune, which makes the commune average a weak guide to what yours is worth.
