We charge $875 per home as our bank fee for processing your loan. That includes our underwriting, processing, flood cert and tax service fee. Some lenders are slightly more, some are slightly less. If you are using and residential bank or broker they must adhere to the GFE rules that others mentioned. Basically they can't just add fees. If it is hard money or commercial as Shane said they can basically do what they want. Doesn't make it right but they can do it. Hope this helps.
