Sunday move outs and key returns

[Tanya Blalock]

So I have a tenant who's scheduled to move out Oct 31st, a Sunday and Halloween.  They want to do a walk through that evening which is not going to happen for a number of personal reasons.

How best to get keys and is tenant responsible for unit until keys are returned?  I was thinking of just getting them first thing Monday morning and have the locks changed on the spot.  BTW, I have a restraining order against tenant so I have to have a rep meet her. 

Suggestions/Thought?  Thanks!
