Previous housing programmes to encourage residential mobility, like the 1995 Programa de Mouilidad Habitaciona!,23 had a limited effect (Simian, 2010). This was partly due to the limited choices for affordable housing in a better location. Subsidised housing has been confined to a few municipalities and neighbourhoods in the urban peripheries. This results in an “immobilising effect” of social housing on residents, stranding tenants in marginalised communities with few possibilities of social or economic progress (Rodriguez and Sugranyes, 2005).
