Influence of a Mortgage Interest Deduction on Homeownership Attainment of European Households

This article provides new European evidence about the relation between the much discussed mortgage interest deduction (MID) and homeownership. We also examine which household-group, based on income or marital status, is (mainly) encouraged via this fiscal relief to own a home. To do so, we estimate multilevel mixed-effects logistic regressions by using Eurostat EU-statistics on income and living conditions data in twelve countries over 2003-2018. Our quantitative study shows that an MID generally fails to advance its purpose of promoting homeownership, likely due to price capitalization. However, our results underscore that there is (substantial) variation across household groups. From the odds ratios, we conclude that the intended positive effect of an MID on homeownership probability occurs only for the highest-income households; those who need the most help with good-quality affordable housing are the most discouraged via this relief to become a homeowner. Since the continuation of an MID remains one of the contested issues in many national debates, our empirical findings provide useful insights for governments around the world that wish to promote homeownership through tax incentives.
