Investigators are on the trail of a long-standing social housing tenant who's been cheating the system and lining her pockets whilst living thousands of miles away in Colombia, South America. Michelle discovers how housing association investigators closed down this lucrative subletting scam and got the property back. And we meet a family who finally get the home of their dreams thanks to a successful breach-of-tenancy investigation. The family of three had previously been crammed into a one-bedroom flat and on the waiting list for a two-bedroom property. Now, at long last, 11-year-old Adam has a bedroom all of his own. In a separate case, Michelle discovers how one social housing tenant moved from London's East End to America's West Coast - but instead of giving the keys to her flat back to the housing association, she gave them to a friend who then proceeded to advertise the flat for rent on a holiday home website.
