This gives me the right to send a Non-Renewal Notice enforced by the standard Unlawful Detainer. 

Unlawful Detainer (aka eviction) is a pain, costs you both time and $$$.It's cheaper by far to just 'buy them out' and I mean offer cash for the keys.You need to decide what to do with any abandoned property and how to handle the deposit, but you're after possessing.

I got the Unlawful Detainer judgment and now there's a civil action on record and they will eat the consequences in the future. 

After that, it is easy to take them to Small Claims; even if you can't garnish their wages or levy their bank account, at least you will have a Judgment against them and here in CA, that Judgment plus the eviction (Unlawful Detainer) will stay on both their court records and their credit report for 7 years.

Generally, if they actually have an "eviction" judgement, then a PM had to file an unlawful detainer because the tenant stayed in the property after the lease was terminated.  

I have been detained by the day JOB.

My wife and I went to the courthouse to observe unlawful detainer (aka eviction) cases. 

I know how to get lists from title reps, Melissa Data, List Source, etc but none of these provide things like homes with code violations, Unlawful Detainer Actions (evictions), or deceased owners.

I start digging into it and it seems like they've had numerous records with the county courthouse over the last several years with several forcible detainer / forecible entry, civil judgement, civil dismissals - all at the same property.1) how does mysmartmove recommend this prospect as "accept"?

Also, could the landlord ADD the additional violations - or would they be required to re-file the eviction if they lose the unlawful detainer 1st cause hearing?
