We are in Scotland. Our completion date on our new home was yesterday. We phoned the vendor to arrange to pick up the keys and he tells us that he wants to rent the property from us until the end of the month. He is now refusing to move as he has nowhere else to go. We have bent over backwards for this vendor, we allowed them a long entry date and then brought it forward at their request. We need them out ASAP but can’t afford to take them to court. What can we do?
