Martin is just outside Tonypandy, South Wales, to see a three-bed mid terrace, bought unseen by a relatively inexperienced developer. He is also in Sheffield, South Yorkshire, to visit a large, derelict, five-bedroom property riddled with dry rot but with great development potential. Jacqui is in Herne Hill, London to see a four-bedroomed, three-storey end of terrace with character and lots of opportunity to add value.
