Does anyone have a good recommendation for the method of serving unlawful detainer complaints and summons to my tenants?  

It is also very important to comply with fair housing laws to avoid unlawful discrimination.

I can purchase materials such as a copy of the landlord-tenant laws of our state that includes a summary to make them easy to reference; a list of tenants served with "unlawful detainer" (evictions) for my county that goes back seven years and is updated monthly; discount price landlording books; tenant education pamphlets for: Lead-based paint, Renovating Right, Mold & Moisture; property management forms/software.

Again let them think you are capable but not sophisticated investor.3 - go to small claims court and talk to landlords leaving that just had to deal with a formal unlawful detainer proceedings.  

But unlawful detainer paperwork is particularly plaintiff unfriendly.

Don't know when it will happen especially when these governors put these unlawful oeders in place.  

According to the theory, because you took possession unlawfully, you are not entitled to be paid for improvements and might even be liable for damages for trespass.I am not saying this is how the lawsuit will go.

“If the landlord makes an unlawful entry or a lawful entry in an unreasonable manner,” then the tenant may go to court to “obtain injunctive relief to prevent the recurrence of the conduct or terminate the rental agreement” and, in either case, “recover actual damages not less than an amount equal to one month’s rent” (A.R.S. 33-1376(B)).

You wont be able to evict unless the lease is up or they are month to month. 2) I am not sure of your local laws, but in MN we cannot evict right now unless there are unlawful reasons and they are a danger to others (this at least was the last I heard for our laws). 

Start with the 3 day pay or quit notice (or whatever your state requires) and then file for an unlawful detainer in court.
