In reading the commentary to 1026.19(e)(2)(i)(A) seems clear to me that you cannot get an intent to proceed until the disclosures (Loan Estimate) has been provided:
Here is the text of the commentary:
19(e)(2)(i)(A) Fee restriction.
2. Intent to proceed. Section 1026.19(e)(2)(i)(A) provides that a consumer may indicate an intent to proceed with a transaction in any manner the consumer chooses, unless a particular manner of communication is required by the creditor. The creditor must document this communication to satisfy the requirements of § 1026.25. For example, oral communication in person immediately upon delivery of the disclosures required by § 1026.19(e)(1)(i) is sufficiently indicative of intent. Oral communication over the phone, written communication via email, or signing a pre-printed form are also sufficiently indicative of intent if such actions occur after receipt of the disclosures required by § 1026.19(e)(1)(i). However, a consumer's silence is not indicative of intent because it cannot be documented to satisfy the requirements of § 1026.25. For example, a creditor or third party may not deliver the disclosures, wait for some period of time for the consumer to respond, and then charge the consumer a fee for an appraisal if the consumer does not respond, even if the creditor or third party disclosed that it would do so.
