Tenant has sign a new lease elsewhere but will not vacate

[Michael Antinucci]

We have a tenant whose lease ended on Aug 31st.  They have not paid rent for Aug and now Sept.   They have signed a lease on another place but are taking their time to vacate the property stopping me from renting the home.  Any advice?   I don't know if this would still be considered an eviction because they actually have a lease somewhere else.    Any help?
