I'm not sure I can agree that that cite would cover a lender error though. In that example, you still owe a corrected disclosure, but to the seller as it affected him directly. I'm not sure just how that would WORK post SALE though
I mean if it already disbursed, seems you'd be at the mercy of the seller.
At any rate, I feel in the OP's case, we are required to disclose the true charge which would have been $495.00 via a corrected disclosure to total $495.00 as it actually was.
