You don't mention whether 'completion' has taken place. I would have thought so if people are actually at the 'moving in' stage. If completion has been done then all monies, etc., have been paid to the appropriate people. You don't need to drop your price by �2,000 as its all been paid already. Also, if completion has taken place then your new property belongs to YOU! Tell the people who are sitting in your house that you would appreciate their moving out asap. If any probs, consult your solicitor who will demand that they move out. (Or, if you so wish, you could charge 'em rent!)
