This book explores the origins, extent and implications of this revival in the fortunes of private landlordism. It presents an in-depth, scholarly analysis of private landlords, the rationales for and ways in which governments have sought to revitalise investment in residential lettings, and their success in doing so. It also assesses the extent to which landlordism has been transformed in recent years and the lessons for policy that can be learned from this experience. The book draws on the extensive research into private landlords conducted by the authors over the past two decades. This includes projects funded by the Joseph Rowntree Foundation, the predecessor departments to the Department for Communities and Local Government, Scottish Homes, and the Economic and Social Research Council. It fills a major gap in the literature about an important actor in housing provision and the built environment. Most of the recent work on private landlords has been published as research reports and there is a lack of book length scholarly study aimed at an academic rather than a policy audience.
