Two sets of fathers and sons, and a seasoned property-developing duo buy and renovate properties in Smethwick in the Midlands, Ramsgate in Kent and Chingford in London. Martin Roberts, Dion Dublin and Martel Maxwell follow their progress to see if anyone can make some money on their auction buys.

A two-bedroom flat in Grays in Essex, a stone-built cottage in Lochearnhead in the Highlands of Scotland and a three-bedroom house in Selston in Nottinghamshire are sold under the hammer. Two of the projects run on for several years, but will any of the developers make any money?
