The research project formed part of a strategic priority for the RTB, to use data and research to promote a better understanding of the rental sector, monitor trends, assess their impact and influence policy and outcomes. For the purposes of the research, medium landlords were defined as being associated with between three and twenty tenancies. Fieldwork for the medium landlord research was carried out between February and May 2020. The margin of error was 6.16% at a 95% confidence interval.
