I think this would qualify as a changed circumstance (comment 1026.19(e)(4)(i)-3 discusses appraisal value different than expected). It sounds like you may have already provided the CD. If that is the case you can not provided a revised LE; your changes would be reflected on the CD.
Comment 1026.19(e)(4)(ii)-1:
Section 1026.19(e)(4)(ii) also requires that the consumer must receive any revised version of the disclosures required under § 1026.19(e)(1)(i) no later than four business days prior to consummation, and provides that if the revised version of the disclosures are not provided to the consumer in person, the consumer is considered to have received the revised version of the disclosures three business days after the creditor delivers or places in the mail the revised version of the disclosures. See also comments 19(e)(1)(iv)-1 and – 2. However, if a creditor uses a revised estimate pursuant to § 1026.19(e)(3)(iv) for the purpose of determining good faith under § 1026.19(e)(3)(i) and (ii), § 1026.19(e)(4)(i) permits the creditor to provide the revised estimate in the disclosures required under § 1026.19(f)(1)(i) (including any corrected disclosures provided under § 1026.19(f)(2)(i) or (ii)).
And here is a specific example from the commentary that may be helpful:
ii. Consummation is scheduled for Thursday, June 4. The creditor hand delivers the disclosures required by § 1026.19(f)(1)(i) on Monday, June 1, and, on Tuesday, June 2, the consumer requests a change to the loan that would result in revised disclosures pursuant to § 1026.19(e)(3)(iv)(C) but would not require a new waiting period pursuant to § 1026.19(f)(2)(ii). Under § 1026.19(f)(2)(i), the creditor is required to provide corrected disclosures reflecting any changed terms to the consumer so that the consumer receives the corrected disclosures at or before consummation. The creditor complies with the requirements of § 1026.19(e)(4) by hand delivering the disclosures required by § 1026.19(f)(2)(i) reflecting the consumer-requested changes on Thursday, June 4.
If you’re redisclosing a CC on the CD, but the rule of ensuring receipt 3 business day before consummatoiin for revised CD aren’t met (APR becomes inaccurate/product changed/prepayment penalty added), then you’d comply by providing corrected disclosures at or before consummation.
Let me know if I’ve misunderstood anything.
