With reference to the process of valorization of public properties in progress in many European
countries, this paper develops an evaluation model to support decisions of Public Administrations involved in
the identification of the best modality of enhancement (concession and lease or sale) of public properties in
disuse and/or underutilized. Although the model can be applied to any type of public property, the research is
focused on religious cultural buildings, that are common both in big cities and in smaller towns. The
assumption underlying the model is that, since the properties considered are complex buildings, generally
characterized by large dimensions, the form of bilateral monopoly market is always verified. The result is a
model of simple use, exportable in any territorial context. The paper must be attributed in equal parts to the
