Six months later, he receives a letter from a lawyer demanding €20,000 because "there are leaks in the foundations." The buyer alleges a hidden defect.

The Documented Transparency Strategy: The best defense is a (sincere) offense. Before the sale, we create the "Property Status Dossier." If we know that the basement gets damp in the winter, we write this in the preliminary purchase agreement: "The buyer declares to be aware of the existence of capillary moisture in the basement and accepts the property in this state, the price having been adjusted accordingly."
