House swapping is the latest trend to hit the property world. With around ten thousand properties registered with swap websites it's a brilliant way to avoid the dreaded property chain and make that move onwards. Kristian Digby meets people who want to swap their home permanently and shows them three properties to find their perfect match. In today's episode he meets Peter and Caitlin Barnes from Derbyshire who want to upsize and Tony and Sue Morris from Grantham who want to downsize. After a day spent road testing each other's properties and lifestyles it's up to House Swap property negotiator Sunita Shroff to thrash out a deal before we find out if the couples decide to swap homes for good.
