I have 4 tenants that are on month to month leases, I served a three day eviction notice and over two weeks later they will still not vacate... what do I do?

Depends on what state you are in. Check the info here:

If that doesn't help, let us know what state you're in: we can probably help you get the details.

In general what you do is go to the housing court and file for a eviction though the court.
