Documentary about some of the nation's wealthiest buy-to-let landlords, who have made a fortune by buying up former council homes, and renting them out to those in need. Among those featured is a Manchester property magnate who buys properties in the city's less desirable areas and rents them to students at up to £400 a month for a room, a London estate agent who only deals in former council properties, and a Kent man who grew up in a council house, and recognises the quality of the construction.
