Here is a new one that just came up. We issued a GFE for a refinance where we listed title insurance of $200 in Block 4. We issued a revised GFE when the rate locked and somehow the revised GFE shows the $200 gone from Block 4 and now in Block 5 (owner's title insurance).

Are we going to have to eat the $200 since we don't require owner's title insurance on this property and our most recent GFE doesn't show any fee for title insurance in Block 4?

not imo. You go back to the last correct GFE if the fee wasn't one that was affected by the changed circumstance.

of course, admonishment to check any redisclosed GFE against the original BEFORE you deliver it is necessary too, again imo.
