My border has gone MIA and rent was due yesterday...legally how long do I wait before finding another tenant?

Question

And legally, what all can I do at this point?

Answer 1

I know Wisconsin law, but perhaps your state is similar.  Serve a 5 day pay or quit to last known address, and then if not paid, begin eviction process.  If this is a month to month lease you are probably safe with just an eviction.  Longer lease terms may be more sticky.  Look online for the Landlord Tenant statutes for your state for more clarification.

Answer 2

It depends upon what your lease agreement says and any state laws that may govern that topic.
