Martin is on the north Wales coast in the village of Penmaenmawr, where back in 2015 he first saw a five-bedroom property spread over four floors. He also heads to Fareham in Hampshire to see a two-bed semi-detached cottage he falls in love with. Dion is in Great Clifton in Cumbria to see a former post office, but will it deliver on its potential?

A seaside flat in Norfolk, a huge house ripe for conversion in London's Forest Gate and a property in Cardiff are snapped up at online auctions by developers who reckon they can make a profit on their investments. Martin, Jacqui and Tommy follow progress.
