I agree with @Mark Munson  You really have to verify the repairs and the ARV yourself. 

Check your state law to verify this is allowed.

They are basically telling you to trust them with no ability for you to verify.

Based on this disclosure and the constraints they put up for showings, inspections and contracts, it is not possible to do proper due dil, which is why I chose to never work with them in the Denver Market.In the immortal words of Ronald Reagan, "... trust but verify"!

I have male seniors whose income is verified thru retirement/disability payments.

It's important that you verify the coverage type though as that can make a huge difference.

I had even set up payments to my bank account through Zillow that was verified.

I verified with the city and investors can add them with meters on single-family homes as long as there are no deed restrictions.

Often what they ask for is not what is always required... it likely says something like "Verify the duration the entity has been in business" and someone decided "A letter from a CPA would be acceptable and easy".  

"Trust but verify" should be applied to every facet of investing and business.
