I’m an urban geographer and housing researcher at the Faculty of Spatial Planning, Vienna University of Technology. My work explores the interplay of macro-structural change (globalization, neoliberalism, financialization) and local institutional contexts in transforming cities and housing systems. I’ve inter alia written on the manifestation of neoliberalism in different housing policy contexts, the shape of gentrification in highly decommodified housing systems, and the homeownership-welfare state nexus in specific social policy settings. While my research has included different institutional contexts (e.g. US, UK, NL), I’ve a particular focus on Austria and Vienna. My current work examines short-term rentals and their social and spatial consequences, local policy responses to the increasingly global urban housing crisis, as well as dynamics of socio-spatial inequality in cities after the Global Financial Crisis. I’ve previously worked at the University of Amsterdam, Netherlands and the Bauhaus-Universitaet Weimar, Germany. I’m Associate Editor of the International Journal of Housing Policy, member of the editorial collective of suburban. Zeitschrift für kritische Stadtforschung, Editor of the journal The Public Sector, as well as regular contributor to the blog urbanizm.net.

The number of individuals and households that own an additional property beyond their primary home is on the rise in several countries. However, recent studies have been inconsistent in describing such properties, referring, for instance, to the return of private small-scale landlordism, the proliferation of second homes, or the significance of dwellings that are held as investment properties. Rarely are these disparate issues considered together, either theoretically or empirically. This special issue mobilizes the concept of multiple property ownership (MPO) to provide a more integrated analysis. In this introduction to the special issue we propose multiple property ownership as a conceptual banner that includes second homes, buy-to-let properties, holiday rentals, intergenerational support properties and safe deposit box properties. While these properties may differ considerably in terms of purpose and use, we argue that they are part of a broader proliferation of property wealth accumulation at the household level. Considering multiple properties together can motivate a deeper understanding of property wealth concentration and changing property relations in the post-crisis context. We introduce a typology of multiple property ownership, discuss the consumption and investment value of different property types, and outline some drivers of multiple property ownership, before considering implications for housing research. We end with a brief discussion of the five articles in this special issue and how they deepen current understanding of multiple property ownership. View paper
