Renters refuse to leave/pay

[Tyson Richards]

I have a rental property that is not producing like I expected. The tenants are also consistently behind on rent, so we are deciding to sell the property. The lease is up tomorrow but our state requires a 60 day notice; so we are changing the lease to a month to month for the final two months. The tenants still have not signed a new lease (sent them one two weeks ago) and are now refusing to pay or sign the new lease for the final 60 days. Is there anything legally we can do to get them to pay? Or are we stuck?? Any help would be great, thank you!
