@Loretta Ratica we have a lot of properties in the Pittsburgh PA market so I can help a little on our process. You give the tenant 10 day notice unless its in your lease that they waive it. Then send in the check to the Magistrate along with the paperwork to file for the eviction hearing. Then go to the hearing and be prepared and detailed. You will most likely win then the tenant has ten days to file for an appeal. If they do not then you can file for possession. There can be a lot more little steps in between but more or less that the protocol. For your first eviction you may want to have an attorney as a consultant to walk you through the process.
I just found out that Section 8 is cutting her off as she missed 2 re-evaluation meetings. I don't know if this is good news of bad news. I also understand from the property manager that she has wrecked the apartment.
