Understanding which households go into mortgage arrears during both boom and bust periods in Ireland is of critical importance to ensure suitable policies are deployed to safeguard future financial stability. Many of the difficulties in Ireland arose from the loosening of underwriting standards by financial institutions. This led to excessive household leverage ratios and provided households with limited buffers with which to absorb shocks (McCarthy and McQuinn, 2017; Lydon and McCann, 2017). The joint effects of labour market difficulties and large falls in house prices led to a situation where nearly one-in-five mortgage loans was in arrears at the height of the crisis (McCarthy, 2014)
