There was a time when many of the expenses involved in putting a mortgage loan together were of very little interest to the lender. After all, the lender didn’t set these fees, nor collect them, nor pay them. They were all passed on to the borrower and cleared up at the closing table, if not before. However, now that lenders must carefully document that they’re not exceeding the CFPB’s fee cap, they are taking renewed interest in the numbers. If the lender isn’t careful, this rule can seriously impede the firm’s ability to profit.
