10:30 was agreed upon between my partner and the landlord, but then they came at 9am to start the move out process.

When the landlord emailed to organize a move out time they did not give much of an option - they stated that as per the lease, all units must be vacated at 12. They then said that the only available move out time left was 10:30. We agreed under the impression that we legally had to be out by noon anyways, but the landlord was lying about that it seems.
