An end terrace in Manchester, a flat in Liverpool and a semi in Stoke-on-Trent are sold at auction and snapped up by developers hoping to make a profit on their investments. Martin, Dion and Jacqui follow their progress, which varies from a swift 20 days to more than four years.

Former childhood sweethearts who became a couple 35 years later invest in a holiday flat by the Ayrshire coast in Largs, and developers who bought property at auction in Wetherby in Yorkshire and Windsor in Berkshire hope to turn a profit. But just like love, property developing doesn't always run smoothly.
