This chapter examines housing cost trends and the growing unaffordability crisis in Greece, situating these within structural changes of recent decades. It provides an overview of the Greek housing system, including tenure structure and property distribution, the impacts of the debt crisis and austerity policies, the condition of the residential stock and housing politics. Housing inequalities and wealth concentration have increased since the crisis, driven by the hollowing out of intermediate social strata and the redistribution of property ownership. Tourist-led housing demand, short-term rental expansion and the entry of institutional and financial actors alongside foreign investment in the housing stock are identified as key drivers of unaffordability. Greece’s market-dominant, homeownership-oriented policies—implemented in partnership with the private sector and focused primarily on subsidies—have had limited impact on reversing exclusionary trends. Although homeownership remains the prevailing social aspiration and access to housing is provided solely through market mechanisms, the chapter calls for a shift towards a rights-based housing model, emphasising the need for social, decommodified housing and regulatory reforms to achieve a more equitable housing system.
