Spainís national housing policy is primarily focused on assisting individuals with limited economic resources in gaining access to affordable housing. Through various programs, rule, and regulations the government has historically sought to increase the supply and affordability of housing. A householdís income has traditionally been the primary criteria used to determine who the beneficiaries of public assistance should be. Using Chi-squared Interaction Detection (CHAID) analysis this study examined how social, economic, geographic, and household preference factors influenced the price individuals were willing to pay for a new home. This study found that while a familyís housing expense and employment status play a role in determining a familyís ability to purchase a home, other non-economic factors also play a role. Particularly important are the familyís intensions of having more children, the municipality of the new residence, and the desire of the family to obtain public assistance.
