Previous research has shown that labour supply – especially of partnered women with supplemental incomes – is positively associated with homeownership status. This literature is advanced by testing whether wanting to move into homeownership before the actual entry into homeownership affects individuals’ labour supply in couples. The empirical analysis is based on longitudinal data from the British Household Panel Survey (1991–2008). Fixed-effects panel regression models are used to predict the labour supply of women and men separately. Labour supply changes associated with homeownership are found to mainly occur when individuals want to move into homeownership and prior to the actual entry into homeownership. When wanting to move into homeownership, women and men increase their labour supply, where women are more likely to take up work and men to increase work hours. For women, the association between wanting to move into homeownership and labour supply is moderated by regional house price changes.
