The FAQs talk about limitations in blk 1 changes in reference to when the loan amt changes, but not for product changes. Other than the webinar ppt slide, I can't find where it clearly states that blk one charges (other than % of ln amt) can not change.
Q: If all or a portion of the charge in Block 1 is calculated as a percentage of the loan amount, and the loan amount changes, can the loan originator issue a revised GFE with an updated charge in Block 1?
A: Yes, but only if issuance of a revised GFE is permissible under 24 CFR § 3500.7(f). In particular, if the loan amount changes and all or a portion of Block 1 is calculated as a percentage of the loan amount, then that portion in Block 1 may be recalculated.
