Arnex-sur-Nyon is a very small commune in the countryside behind Nyon, between Borex, Crassier and Eysins, close to the French border.
Flats in Arnex-sur-Nyon change hands around CHF 11,300 per m², well above what the rest of Vaud 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. No single period defines Arnex-sur-Nyon, though before 1919 leads with 27 percent. That mix works in a buyer's favour, since you can choose between period character and low running costs without leaving the commune.
At 4.3 rooms and 127 m² on average, homes in Arnex-sur-Nyon are sized for households rather than single occupants. If you are looking for a studio or a two-room flat, expect a thinner choice and less room to negotiate. The market in Arnex-sur-Nyon 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 Arnex-sur-Nyon comes out at CHF 11,300 per m², a gap of 43 percent against the Vaud median. That figure covers every flat sold, whatever the floor, the age of the building or the state of the kitchen. The premium over Vaud 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 Nyon district, Arnex-sur-Nyon lands 8 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 8 percent premium on flats over houses in Arnex-sur-Nyon 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. The last twelve months added 2.3 percent in Arnex-sur-Nyon. 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.
The 25-year record opens at CHF 4,000 and closes at CHF 9,500, +138 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. The figures above describe Arnex-sur-Nyon, 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.
