Is it ok to change the escrow amount and hazard amount on the GFE when doing a change of circumstance and have to re-disclose?

Not unless your changed circumstance related directly to those fees, but since those are unlimited tolerance items, there's really no need to re-disclose them.

I agree. Only information affected by the CC should be revised on the new GFE.

The problem that I am having is that my front end system does not have the capablility to capture the original GFE and when the underwriters update the taxes and insurance for DTI purposes, it carries to the new GFE when a change of circumstance occurs, thus changing the escrow and hazard amounts.

I have the same problem, it's actually more work with our software to try to redisclose while maintaining the original escrow and daily interest charges (both unlimited tolerance).
