This article considers how house-sharing – sharing a home with other, usually unrelated people – is mediated by digital technologies. Drawing on academic literature on house-sharing and self-(re)presentation in digital cultures, interviews with share-house residents in Melbourne, Australia, and user posts in house-sharing groups on Facebook, we identify a sequence of steps and stages integral to the process of (re)forming a share-house in the competitive private rental market. These include advertising, screening, vetting, digital interactions, interviews and house tours. Considering this multi-stage process from the dual perspective of ‘home-seekers’ (applicants) and ‘housemate-seekers’ (existing household), we analyse how both parties deploy representational and communicative strategies, explore the conventions and complexities underpinning these interactions, and present a conceptual framework that explicates the process. The article contributes to scholarly debates about mediated practices of self-(re)presentations, and about house-sharing as a significant practice in a housing market that renders home ownership increasingly unaffordable.
