@BT. Go this Route

@BT...   This is the route we are taking if necessary. If any problems on the exit you then go with  Summary Process with served notice to domicile and places of employment.   Be ready to serve immediately after the move date if the move hasn't occurred.   Plus, you should get a complete photographic record of current conditions with witnesses to litigate for any malicious damages. We got ours during the code inspection, which   is  actually a good tool for this.   Good luck with yours.  Sorry this happened to you too.  Hope this helps.
