Over the last few years several documents have been published about the need for more efficient and cheaper selection processes in municipal land sale procedures. The current costs of selection are often considered too high. New, light selection methods−in which a partner is chosen based on a vision instead of a design−are suggested as a solution. However little research has been conducted about how to choose a fitting process to sell municipal land. Therefore the research question of this thesis is: ‘How can decision making regarding selection processes for municipal land sale procedures be improved to decrease transaction costs for public and private parties involved.’ A basic framework for the research was set up by performing a literature study. Subsequently, a document review was conducted and interviews were held to study two specific cases. Additionally, several general examples of processes in competitive land sale procedures that raised transaction costs were explored. The literature review and the empirical review have led to a synthesis that has set the foundation for a framework for municipalities to make improve decision making for the design of competitive land sale procedures. This has led to the conclusion that there is not a single optimal solution. Multiple factors have to be considered in light of the specific case when choosing a fitting process for a competitive land sale procedure. From this research it is deducted that it is advisable to select one process as a starting point based on a balance between goals and transaction costs for the specific plot. From this starting point municipalities can use transaction cost theory to improve cost efficiency of the preferred procedure to come to an optimal selection design for a successful competitive land sale procedure.
