The paper evaluates the role of retiree migration on housing markets in Orihuela, Alicante, Spain. It checks the flow of migrants from 50 to 65 demanding housing and evaluates the effects on housing construction and prices coming from this phenomena. Analysis is focused on Valencia Community because the retiree migration is a new trend affecting just to some of Spanish areas where Alicante Province is one of the most important receivers. We use multivariate techniques to estimate a model including demographic pattern which differentiates between retirees and others migrations. Results suggest that retirees migration is encouraging other type of migration to the same destination areas.
