I started this project hoping i could efficiently review the most amount of properties in order to maximize the potential investment options to bid at auction....this is what I have so far.First thing i did was to create the listings, I matched the properties been auctioned with their corresponding pics and the property specs (rooms, size, floors etc.).Second, for each property I automated the data collection process from public records and created a report with: Foreclosure info, owner info, taxes data, liens including mortgages , satisfaction of mortgages,  assigments, violations and permits and court dockets.This data is updated daily to capture new filings (specially the dockets to capture bk and motions to cancel sales)Now that i have the data i can apply my personal "preferences" to go through the report and in a few minutes discard  properties that have certain attributes I "dislike". 

Also, I believe I meet those other requirements, such as purchased by an LLC, keeping of clearly separate records, etc.

Having your documents in order and keeping good records helps quite a bit.Choose someone with a history in business, and don't get hung up on the direct buyer / broker comparison.

The county website has maps/survey records, but sadly there aren’t any available for our property.

Once you record the deed with both of your names, it is now 50% (or whatever your JV agreement says) yours

I am looking for any feedback on this company's mentoring service which provides leads from proprietary software scrubbing tax records for wholesale leads and a cash investor list.

I've tried accessors office and recorders office

The owner (looking at other property records) seems to like tax forclosed properties (owns 5).  

I have searched court records in the past.

But if the contractor doesn't have a completely clean record, I wouldn't take on that risk and give up a large portion of your profits.
