You turn the key and cross the threshold into the house when suddenly it hits you, someone is turning your key in your door and walking into your house and it’s too late to turn back.
House swapping started back in the 1950’s, mostly practiced by teachers and university lecturers, but today more and more people are choosing to hand the keys to their home over to strangers and accept their keys in return. It sounds absurd and immediately you think, but what if they thrash the house? What if? Well there are a million ‘what if’s’.
