I hope this adds favorably to the discussion:
It seems to me that if you charge this fee on all loans made, it would belong to the bank.
If the fee belongs to the bank, it should be disclosed that way on the RESPA docs -- as a fee charged and retained by the bank. The fact that you charge the fee on all loans does not lead me to believe that it is collected solely for the purpose of paying the processing fee associated with secondary market sales. If it were, you'd have a problem explaining it for loans that you did not intend to sell. If it were solely for paying that third party, then I'd think you would disclose it as a fee paid to the third party (as Dan has stated).
Based on your explanation, I'm inclined to believe that the processing fee that you pay to the purchaser is part of a secondary market transaction (not an expense that was collected from the borrower at closing) and not subject to RESPA disclosure requirements at closing.
I think this is consistent with Dan's position.
