The underwriting fee for a mortgage is determined by the amount of the mortgage taken out.
But for example if you take out a $348,000.00 mortgage loan then the amount of the underwriting fee for that mortgage would be roughly $895.00 plus you'd also have fees such as a loan origination charge of around $250.00 plus a $695.00 processing fee so with all those fees it would cost you $1,840.00 for the underwriting fee with the other needed fees added into it.
