I'm getting into wholesaling so my first plan of attack was to go to my target county's courthouse here in Illinois. 

So, I am a bit confused on how to attack the proof of funds concept.

An attacker can only go after the LLC, not the owner personally.

I appreciate the info and will diligently attack it.

On top of that most of the time it's illegal as well.What I'd do if I were you (well actually I am me & this is what I did to get started, today I run a $50 million portfolio so it's a pretty solid plan of attack). 

Since the Series LLC is an LLC, its first going to be attacked by piercing the veil like a standard LLC.

I would say it comes down to what is in your lease.My lease says they are responsible for the remainder of their lease or until I have it rerented.My lease also says if they have pest problems during the first 30 days I will take care of it, beyond that they are responsible because I can't control how clean they keep their place and leaving out food attacks critters.Will their deposit cover the last month and is their any damage or is it mainly just a cleaning issue?

Remember, the person that's going to attack someone already has a plan plotted out and even possibly someone with them hiding out,so you're at a huge disadvantage.  

Set your goals, have boots on the ground, and plan your attack.

You still need insurance and umbrella insurance, so what @Ashish Acharya and @Dmitriy Fomichenko is valid, but 1. insurance doesn't cover you in all scenarios and limits and 2. is not doing anything for you in case of an "external" attack (as with the case of a malpractice lawsuit).You might be able to get the FHA loan and then transfer the property (with a warranty deed!)
