I am often asked about current and historical property pricing data in the Haute Savoie. It is a fair question. In the UK very accurate and open data is available. The answer for France is not quite so straightforward. The Notaires collect all the data, it is publicly available on a broad scale. More accurate information is available on a pay basis, it's not easy to get though. the free stuff has to be read with caution!
Below is a coloured map of the Haute Savoie, the redder the colour the more expensive the commune. It makes sense, Chamonix, Megeve, La Clusaz, Annecy and Les Gets come out as the most expensive. Followed by Morzine, Combloux and the rest of the Chamonix valley. Manigod, Le Grand Bornand and Chatel follow along after that. Samoens should be in that last group too but a quirk of stats has knocked it down a peg.

Take the actual value/m2 with a pinch of salt, this always reads too low in our experience. The price trend graph looks about right though. But read the title, it is for the whole of the Haute Savoie and not for each commune as it seems to suggest on the website! So it shows a massive price increase between 1999 and 2007, a small drop for the following 2 years and then stability. We think this will start to climb again at the end of 2015 and into 2016 driven by the weakened Euro compared to Sterling.
If you zoom out a bit on the commune map you start to see what sort of bubble there is in the ski areas. We already know that you only have to drive 15 minutes from the resort to see the prices half, well looking at this and you'll see you have to drive an hour from the resort and the prices drop to 25%.
