A flat with huge potential in London's Earlsfield and terraced houses in Wombourne near Wolverhampton and Ynyswen near Treorchy in Wales are all sold under the hammer. Martin, Lucy and Dion catch up with the property developers, who are all hoping to make some money from their auction buys.

A first-floor one-bedroom flat in London's Stepney Green, a three-bed semi in Dartford in Kent and a one-bedroom flat on the 17th floor of a block in Salford are all sold under the hammer. The investors all have very different ideas for their properties - but will any of them see a return on their investment?
