On any refinance where the MIP refund exceeds the Upfront MIP required on the new loan, the overage will be refunded directly to the borrower from HUD. The lesser of the MIP refund or the new upfront MIP should be subtracted from the unpaid principal balance before calculating the new mortgage amount.
I don't know the high cost limits as it doesn't affect me in my area.
