If you obtain information that a cost will increase by more than the applicable tolerance limit the day you sent or delivered the CD for the loan, you can't use a revised LE to adjust your good faith estimate for that cost, but, as Randy said above, the Bureau's "TRID 2.1" rule allows you to issue a revised CD to accomplish the task. That revised CD must be provided or sent no later than 3 business days after learning of the increase, or at the closing, whichever comes first.
