I thought about the possibility of doc stamps. Some states used to impose this type of tax on certain loan-related documents (but I can't remember if it extended beyond security instruments.) Loosely described, this type of charge could be called a documentation fee or charge.
And...loose descriptions are always a problem. Jargon exists within the industry, regionally, at the state level, bank-by-bank, and even among the different lending units within a single bank. My first step has always been to strip away all the jargon and describe the nature of a charge. Only when a fee is described in generic terms can you apply the "comparable cash transaction" principle and the more specific definitions and exclusions found in Section 1026.4.
