The best thing to have in court is a police reports.  

Hi Experts, I am looking for latest data about how much it will cost to build a 20-unit apartment complex in CA Central Valley (in/around Tracy / Modesto / Stockton) with a GC vs self-managed project with an experienced architect.

eviction or small claims court?

My thought process on this was should I ever go to court over some type of a matter I would have a log detailing the tenants time at the property and what all has gone on to be able to present in court.

Others, depending on their structure and complexity may not be able to provide it until much later.

I'm assuming all this damage is going to be above their security deposit so you might need to take them to small claims court. 

HI @Beth Thomas, if it went back to the bank for sure then you should be able to search your county assessor's records (either online for free or for a small fee) and determine who the current owner is, or else you could try your county court clerk's office and find the loan documents that were filed there against the property. 

The loan application process for the 203k is NOT complex.

The prior owner has right to redemption if the court or the auction or anyone didn't follow time lines and rules - but can they come up with the money? 

Currently there are no open courts for evictions even if you had one already filed and in hand.
