Difficulties in accessing housing are one of the primary challenges faced by young adults during transitional phases in their lives, leading to subsequent instability. This instability arises from various factors, including constraints within the housing market such as unaffordable prices for both homeownership and renting, as well as challenges related to precarious employment and low incomes. In Lisbon, leaving the parental home poses particular difficulties, driven not only by the soaring housing prices but also by the broader impact on young people's autonomy, life transitions, and family expectations. The increasing instability in young people's housing situations and the emergence of new residential preferences necessitate a critical examination of alternative housing solutions. In a city like Lisbon, where affordability is a major concern, it's crucial to understand the diverse strategies employed by young individuals to navigate housing access issues and gain independence during transitional phases. New urban and residential practices and values among younger adults, such co-housing, home sharing, and relocating to peripheral areas may be observed. These shifts have various impacts on their lifestyles, residential habits, and domestic experiences. Drawing on eight exploratory in-depth interviews, this article aims to explore some advantages and challenges of young adults being compelled to share a house with strangers. A ninth interview with the creator of the documentary "A Temporary Situation" offers complementary insights into the daily lives of individuals sharing housing in Lisbon, focusing on the potential disparities between housing aspirations and realities.
