By 'RE system', I assume you're talking about a loan transaction. In which case, the appraisal is one of the higher fees in said bundle. Typically around 4-6 in order of magnitude behind origination, discount points (if paid), title insurance, survey, and escrows. Fees that are typically lower than the appraisal are credit report, flood, tax service, VOE, VOD, IRS transcripts, notary, closing fees, HOA transfer fees, recording fees, and other transfer fees (to name a few).
Maybe stick to stuff you actually understand, J.

Or, if you do understand and are being intentionally duplicitous, please stop. There are folks reading these posts that might actually believe you. Doubtful, but possible.
