I have a tenant that won't leave. I contacted her to see if she wanted to renew her lease in plenty of time, she kept pushing me off, and finally told me that she didn't want to renew. Now that I have a new tenant coming in, I need to make sure the unit is ready, but she won't leave! She hasn't moved her things out, she hasn't done anything! I tried speaking to her about it, telling her that her lease was done and that I needed the keys etc... and she says she changed her mind, she'd rather just renew the lease. now what do I do?
