One tip is to start looking into meetups to connect with investors / others in the REI game (in person/online).

please send me a case example I'd love to read. that's one appraisal. the knowledge I have as a licensed general contractor working with investors from 5 cities at a time all over the country buidling 3 different floorplans I would say trumps one ADU you read about online 

You should be able to send it to the court clerk with the case number (you should be able to find it online or call the court).

The challenges in real estate teach you invaluable lessons that you might not gain otherwise.I also invest in Chicago, so I have a few thoughts in response to the questions you raised.

Always validate what you read online, things change, I could be wrong, but use this as a starting point in your research.What Is an ADU?

Thank you for your responses, @Douglas Skipworth and @Mark Ainley. 

Thanks for the response.

With online access to almost every jurisdictions property recordings, lenders today use software that automatically searches property transfers for transfers involving their loans.  

@Michael K Gallagher Thanks for the response.

It was a subsequent post in response to my question that OP made clear it was because the state required deposits to be held separate.
