Think of the reg as a “rolling” 30 days. The creditor has 30 days from when they receive a completed application, that is, all the information they need to make a decision. If a credit report comes back bad, the bank has 30 days to let the applicant know from that time. If the credit is OK, it goes to the next steps, verify income, assets, property value. If the first receipt a week later is income, the creditor has 30 days from that point. Etc., etc., etc.
Like Randy mentioned about the appraisal, the caveat is that ordering all documents should be as expedient as possible. Read the definition of “completed application “ in 1002.2.
Integrity. With it, nothing else matters. Without it, nothing else matters.
