How do I get my tenant to remove belongings?

[Lauren Slattery]

My renter was given a 30 day notice per our rental agreement. The 30 days should of been July 16th. She claims she cannot move her things out because she has a high risk child who should not be out because of covid. I only learned about his condition when covid happened. She has found a new place to rent but will still not remove the rest of her belongings. She has not stayed or slept at rental for two weeks now.  She has also not paid rent for the month of July. Are my hands tied? I have prospective renters wanting to rent by September and need to do repairs to property since she has not been clean and disrespected property. What can I do in this situation?
