Foreign investment in residential real estate -especially by new middle-class and super-rich investors -is re-emerging as a key political issue in academic, policy and public debates. On the one hand, global real estate has become an asset class for foreign individual and institutional investors seeking to diversify their investment portfolios. On the other, a suite of intergenerational migration and education plans may also be motivating foreign investors. Government and public responses to the latest manifestation of global real estate investment have taken different forms. These range from pro-foreign investment, primarily justified on geopolitical economic grounds, to anti-foreign investment for reasons such as mitigating public dissent and protecting the local housing market. Within this changing global context, the six articles in this special issue on the globalisation of real estate present a diverse range of empirical case studies from Canada, Hong Kong, Singapore, Russia, Australia and Korea. This editorial highlights four methodological challenges that the articles collectively highlight; they are (1) investor cohorts and property types, (2) regulatory settings, (3) geopolitics and (4) spatial differences and temporal trajectories.
