The Break-Even Analysis applied to urban renewal investments: a model to evaluate the share of social housing financially sustainable for private investors

In this work an evaluation model to support Public Administration decisions in planning urban strategies that aim to involve private investors has been developed. Considering the unfavorable economic climate, any territorial transformation can be realized only if the public needs meet the financial feasibility of the initiative. For this reason the model allows to define i) the maximum amount of subsidized housing to be realized by the private investor; ii) the administered selling price to be applied. The model has been developed translating in the field of urban planning the Break-Even Analysis, a tool borrowed from the marginal economic theory. It is applied to a real case study concerning the urban renewal of an unused area located in a city in southern Italy. The outputs obtained confirm the potentialities and the user-friendly configuration of the model.
