A pretty cottage in New Mills in Powys, a bungalow in Bilston in the West Midlands and an end terrace in Norfolk's Great Yarmouth with holiday let potential are bought at auction. The developers have set budgets but have to re-evaluate when faced with soaring building material costs.

Martel and Tommy oversee some fantastic renovations on auction buys in Carlisle, Rosyth and Shepherd's Bush.
