I've got a mini library of books about property and living in France, but this is by far the best. And at over 400 pages it is easily the most comprehensive.
It really does cover all the ground from looking for a house, finding agents, negotitating, getting a mortgage and then moving in. It also has a huge section on living in France (including, finally, the definitive word on cartes de sejours!) and working in France. I'm thinking of setting up a business in France, so I found this last section especially useful.
If you want to know why so many people are buying houses in France - read the case study of the man who bought a house in Deux Sevres and met his neighbours!
