Martin Roberts meets a man who buys a house in Wales to give his mother-in-law who lives next door peace of mind after it has stood empty and neglected for 12 years. And two other properties in Derbyshire and Kent also get renovated - but do they turn out to be good investments?

Lucy finds hidden depths in a Ramsgate listed building while Martin meets a buyer who's more than a little surprised by his auction purchase in Dunmurry, Northern Ireland. And in Earls Court, London, we find a little flat with big potential.
