A commitment fee is a banking term used to describe a fee charged by a lender to a borrower to compensate the lender for its commitment to lend. Commitment fees typically are associated with unused credit lines or undisbursed loans. Since this was paid in line with acquisition of the loan, and not acquisition of the property, you'll include it in the total of your amortized costs which get deducted (not depreciated) over the life of the loan.
