Next after three days they paid, great ! all well that ends well, However if they dont pay I proceed with the eviction yes it cost but its much cheaper than having the tenant stringing you along.
You have right too use them, help the tenant to understand that you must follow the rules to protect them and you.
I would just evict her if I was you dont wait another minute if you dont evict her, she might never leave you never get her out and you loss more in the long run including your sanity.
If you have not previously filed an eviction or been in this situation before, as previously advised, it is very important that you have professional legal advice as to the proper course of action.
If an eviction is required and the forms are not filled out properly (as many owners don't know which ones are required or how to file them) they can be kicked back by the courthouse, thus extending your eviction.
