Just seen this interesting article about who is buying property in France and where they are buying it. It seems the British are still the biggest foreign buyers but that the proportion of non-French buyers is falling. There's a very interesting map showing the areas of France and what percentage of each nationality is buying in those areas. Worth a look.
