Posting listing without tenant consent

[NA Jordan]

I have a rental property in Dover NH. My tenant just told me she may need to end her lease because she does not have the means to pay it. She is not positive if funds will come through. She told me if she cannot she will move out the first of the month. I just asked for her permission to post it, but she said no. Is it in my legal realm to advertise it, but not show it until I have permission???
