Hi ,I am looking also and found this on Google :-

The cheapest regions in which to buy property in France are undoubtedly Limousin and Auvergne, both of which are non-coastal regions in central France. These regions have suffered from rural depopulation in recent years due to a lack of large towns and industry resulting in relatively high unemployment. Consequently, parts of these regions are very remote and sparsely populated. Limousin and Auvergne are nevertheless, up and coming areas as far as the French property market is concerned. The increasing number of buyers looking in these regions has not yet driven property prices up significantly and property here still represents excellent value for money. A property in Limousin or Auvergne can be as much as two or even three times cheaper than its equivalent in size and quality in the nearby Dordogne. It is this comparative value for money that has drawn house hunters to the region in recent years. However, the peaceful surroundings and recently improved transport links are other points in their favour. It is still easy to find renovation projects, including barns, cottages and farmhouses in Limousin and Auvergne at truly bargain prices. Small rural cottages or village houses needing work can be snapped up for less than £20,000.
