You should also ask for meeting minutes, as these provide additional insights into the operations, pending assessments, violations, landlord/tennant issues, etc

There are very few agents or brokers that have the depth of knowledge that a seasoned appraiser has just by shear scale; we look at thousands of properties per year instead of a few dozen or even hundred.

They've said on FB that they buy in bulk because they usually have dozens of flips going on simultaneously. 

However, as others have stated, we need the address to even begin to assess the issue.

Just honestly assess if true damages have really been done and have been caused by the tenants above normal wear and tear and the paid for pet fee.

As a buyer I'm assessing if it's a good deal for our portfolio.  

Considering my own business and personal interests, I explored this idea when my wife and I were there this past June, looking through dozens of property listings on the streets and posted in back corners and brokerages.

One property was purchased for 17,000 and the assessed value is 55,000.

What makes it difficult on this property is that the seller challenged her assessment, and got it reduced to about half of the values in the neighborhood.  

There are dozens of reasons why pre-approved buyers get into a contract to purchase and then can't secure the financing.
