ABSTRACT Homeownership has been shown to be related to various aspects of well-being, although both the causal nature of this relationship and the possible channels behind it have been difficult to identify. We examine an important mechanism which could be responsible for the positive effects of homeownership, namely its role in providing material security in old age. Using data from 15 European countries, we analyse the relationship between homeownership and material security, as measured through subjective evaluation of the likelihood of being better or worse off in the future. We find that homeowners have a higher level of material security than renters, and this association is especially strong for those living in big cities. For this subsample, in comparison to renters, owning a property in the top quartile of the home value distribution is associated with an increase in the probability of expecting to be better off in the future by as much as 43%. We interpret the results as support for the argument that homeownership offers a very particular form of material security, which, through reduction of perceived material risks, may be behind its positive implications for well-being.
