Bristol couple Bob and Jenny Lait are planning their retirement. Now that their children have flown the nest, they want to start a new life and find a new home, but they can't agree on the location.

Property experts Jonnie Irwin and Jasmine Harman show them dwellings at home and away for their budget of £200,000 to help them decide.
