Delegate this to a law firm specislizing in unlawful detainers.

Hi Chelsea, I get my list from a local provider that gets them by going directly to the county and looks up unlawful detainers in the recorded judgments.

speaking with my property manager and the attorney that we went through, I can evict them by filing an unlawful detainer.

I file "Pay or Quit" notice followed by an unlawful detainer petition in state court.

Do I have to go through that whole 3 - 6 month unlawful detainer legal process?

@Pedro Oliva Unless you'd also consider yourself a good prospect for a low cost, do-it-yourself brain surgery kit, pay an attorney to complete the U/D (unlawful detainer). 

In a recent eviction of ours, the tenant sent us a check for part of what he owed after the eviction process was underway and after we had filed with the courts for unlawful detainer.

This is my third or fourth eviction, but this time the court clerk just mailed back my request for default judgement, rejecting it stating "no service on unnamed occupants".On the unlawful detainer complaint, the tenant was named with "does 1 through 10".But the sheriff only served the named tenant and no other occupants were identified.  

If they respond to the unlawful detainer complaint and wish to go to court, it looks like it could take a month or more to get them out.  

You will likely have to file an unlawful detainer versus standard eviction.
