Showing tenant occupied apartment

[Troy B.]

I'm a new landlord and I have a tenant that just informed me she is moving out at the end of the month. I have some prospective new tenants that want to look at the place but can only make it during hours she isn't home. She is now telling me she doesn't want anyone in the apartment while she isn't home. Do I have the right to show the apartment with a 24 hr notice even if she isn't home?
