Once you are out, we will inspect to verify there's no physical damage to the rental and refund your deposit immediately.

It's been great as a noise monitor (and I can also see temperature readings which are verifiable and solid).

As @Sebastian Marroquin stated it is important to verify that it is a legal ADU.  

Can you verify that the prior eviction was due to a divorce?

What documents do they require, what credit scores do they allow, how do they verify previous rental history, etc.?

Dodd Frank was very specific about lenders verifying homeowners' income when they purchase a home.

In my experience, you will always have to get a credit check as part of the application process as the lender needs to verify your credit history for anything outside of the norm and to see your credit score.

Homeowners are going to be required now to actually verify licenses, which isn't hard at all to do. 

Verifying last 2 years of rental history very important!
