Vacating Timely

[Mark Douglas]

It's move-out day for my tenant, but she isn't ready.  (Still cleaning, packing, etc) 

Is there anything I can/should do to ensure she actually leaves today?  

Do you charge a late fee or pro-rated rent if tenants aren't out the day they're supposed to leave??  I don't want to give her the idea that she can stay over a few extra days to get things together.  I'd already given her a written 30-day notice, with a friendly verbal notice 2 weeks before the 30 day letter went out, so they've had 6 weeks to get ready.
