Im looking at a property that has two legal units and a third that is not.

CAFEFULLY used, sub to and seller financing can be good for both parties. 

While you can't create limitations against their lease and legal rights they have for quiet enjoyment, things like keeping common areas free of clutter or routine maintenance items that are tenant responsibility can often be added to help keep the expectations on both parties clear.

Third, if it is a Fannie loan, you can transfer from personal ownership to LLC, I believe, after one year.  

This is bogus if buyer and seller are independent parties (if the parties are associated then I understand setting true value) as there is usually a reason for the discount purchase (risk items like unpermitted work, crazy low rents in rent controlled area, hoarder, heavy need of rehab, etc).  

The second part is the apprentice 1 on 1 coaching where you do the training at your own pace and if you find a good deal you send it in.

I want to understand how many properties are bid on by third parties and how many revert to lenders.

If you do offer something like this, as you likely know, be sure to document it with a lease amendment signed by both parties.

Otherwise many many many agents spend a lot of time and effort finding property and writing contracts only to find that the funds can't be transferred, or they don't have immediate access to the funds, or they need some kind of approval from 3-4-5th parties, or there are exchange restrictions, or 9000 other excuses.You probably need to find them a commercial broker who can handle whatever kind of investment they want to make. 

Neither remote or 3rd party management will work...it will take local, hands on, full time management.
