Cheap Life Assurance

I want to leave Europe, but still live with in French territory for reasons of social insurance (RMI, CAF). since I have little money I am looking for a lifestyle very different, quiet, and inexpensive.

Hello! I lived in France (Europe) on two occasions. (Just left a few months ago actually.) Also lived in Reunion and I am now living in New Caledonia. The cost of living in La Reunion is at least 30% higher than in Europe, France and there is not much work available. New Caledonia is still more expensive. For example, we find the price of groceries here at least twice that in France. The rent is also very high. It is a peaceful way of life, but far too expensive. It is true that we have no heating costs and what type of thing, and no cold weather, but it is still cheaper to live in metropolitan France.
Maybe you should consider moving to a small town or a new department in France.
I do not want to discourage you. The islands are beautiful and people tend to be friendlier and more open than in Europe. We love the islands, but the cost of living is quite high.

Being from Guadeloupe, I can honestly say that there is almost no way to live cheap in the French Antilles, French Guiana and Reunion ... You know the unemployment rate is quite high in most of the islands.
People tend to think that the presence of sunlight is enough to live well, but this is not true at all.
Be sure what your plans are and try to prepare yourself thoroughly before making any decision.
