Non-Performing Loans, Non-Performing People tells the previously untold stories of those living with mortgage debt in times of precarity and explores how individualized indebtedness can unite resistance in the struggle toward housing justice. The book builds on several years of Melissa Garcia-Lamarca's engagement with activist research in Barcelona's housing movement, in particular with its most prominent collective, the Platform for Mortgage-Affected People (PAH). What Garcia-Lamarca learned from fellow activists and the movement in Barcelona pushed her to rethink how lived experiences of indebtedness connect to larger political- economic processes related to housing and debt.

The book is also inspired by feminist scholars who integrate the lens of everyday life into explorations of contemporary political economy and by anthropologists who connect macroprocesses to lived experience. Distinctive in how it integrates a racialized, gendered, and decolonial perspective, Garcia-Lamarca's research of mortgaged lives in precarious times explores two principal phenomena: first, how financial speculation is experienced in the day-to-day and differentially embedded in the dynamics of (urban) capital accumulation, and second, how collective action can unleash the liberating possibility of indebtedness.
