A semi in St Austell in Cornwall, a mid-terrace in Croydon in London and a former hotel in Bitterne in Southampton are sold under the hammer. Martin, Lucy and Dion meet the new owners to hear their ambitious plans to make money from their investments.

Martin Roberts meets a young family with a toddler and a 12-day-old baby who buy a house in Wood Lane near Stoke-on-Trent, while Dion Dublin and Lucy Alexander talk to developers who have bought a terraced house in Darwen in Lancashire and a maisonette in London's Plumstead.
