I am working with an "affiliate" of Wells Fargo and gave him a ton of information so far, and now he is asking for a $400.00 underwriting fee that he says is imposed by wells fargo. We haven't even gotten a pre-approval yet! He says we can get back all of it but $40 (for credit reports) if we DONT get approved. However Wells Fargo website says that pre-approval is free on a home loan. Any advice?
