Rental tenure and rent burden: progress in interdisciplinary scholarship and pathways for geographical research.

Rental housing accommodates more than a billion tenants worldwide, and in recent years, rentership has been increasing in some countries. Given reduced access to homeownership in various locations due to several causes, it is critical to focus on rentership which has received relatively less attention compared to homeownership, especially within the geography scholarship. In this review article, we identify four key themes that have naturally emerged from the close examination of recent interdisciplinary literature on rentership and rental affordability. These include: (1) rental housing financialization; (2) the proliferation of single-family rentals resulting from the U.S. foreclosure crisis; (3) the determinants and consequences of rent burden; and (4) the relationship between rent burden and regional economic specialization. We discuss these themes and propose potential opportunities for the geographic analysis of rent burden, its determinants, and their relationships with regional economic specialization. We posit that the four identified themes have been developing in apparent isolation, thus making scholarship less consistent. Moreover, research on rent burden is disjointed in itself, which makes it difficult to establish a unified narrative and interlinked subthemes within the rent burden literature. Nonetheless, we contextualize the four themes in their application to geography and frame our discussion around the central notion of this article-rent burden.
