Since the 1970s, with the expansion of the mortgage market, numerous measures have been introduced to support low-income households’ access to home property. What is the experience of working class homebuyers who take out a mortgage? And how does it affect their household budget and domestic organization? Combining statistics and ethnography, this analysis of working class people with property loans shows that while they report greater difficulty in managing their loans than other social categories, this is due not solely to their social distance to the banking system, but also to the greater structural complexity of their repayment plans: the loans contracted are more varied, more numerous, and extend over longer periods. Moreover, as these borrowers often barely satisfy the criteria of solvability defined by the banks, their access to credit depends on specialized credit companies and face-to-face relations with banking representatives. The debt trajectories of these individuals reflect a sentiment of financial insecurity and dispossession, but also a strong aspiration towards home ownership.
