Good luck. A lot of good advice here. As long as you have a judgement, they should be out with the assistance of the sheriff. Don't communicate with them any further, particularly after the threats. Put ACR on your phone to record calls. If you are threatened again, file a complaint. If it isn't on paper, it didn't happen as far as police and courts are concerned. In NY, I don't think you are allowed to accept money once you are evicting or it is a new agreement. Since local laws differ, I'd focus on advice from local people. I especially like the eviction specialists.
If you think it will work, send her a message in writing offering to pay one month rent to leave and an additional month's rent if apt is in good condition to be paid after they are out and you've inspected. If they go for it, make sure your inspection includes turning on all water sources and checking outlets. One of the podcasts had a guy speak about a place where the tenants had removed the pipes and electrical but left everything looking good on its face lol.
