I'm thinking of finding a buy and hold investor that will pay the reinstatement and do a sub 2 transaction.

Now that you own this property, the IRA may never be involved in the transaction. 

The best way you could benefit them would be referring your leads that don't go the wholesale route to them, but to make this effective you may want to partner with a newer agent.

The split roll won't effect any residential real estate.

Yes, I will be paying Cash to cover this transaction. 

In fact, on the larger properties I'm booked a year in advance.Most of the transactions are done  via email and rarely do I meet/speak to the tenants unless there's a maintenance issue.Cons:  SCAMS! 

There should NOT be an SB2 fee on a resale transaction.

You go with what the bank will fund, or pay the difference, or back out of the transaction.

But its likely you are simply overestimating the effect of an inquiry. 

Additionally, you may find that the FHA requirements and upfront PMI puts an undue cost on the transaction and are better off just setting up a HELOC after refinancing into the conventional on your first property, then using the HELOC to fund 10 to 15% of the next transaction.
