River Girl -- Don't know if your timing questions got answered, so let me try.
If you are going with the Risk-Based Pricing notice (NOT the exception notice), you are correct that you can't provide it at application because you won't have made a credit decision then. You could theoretically provide it with your 3-day disclosures if you've made the credit decision by then, but you indicate you do your 3-day disclosures "instantly" so that won't work.
The theory here is that until you've made a credit decision, you don't know whether the customer has gotten a risk adjusted price; therefore, the disclosure has to come after that. I'd recommend sending your Risk-Based Pricing notice with your "Congratulations, your loan is approved" letter.
If you go with the exception notice (i.e., the replacement for the Notice to the Home Loan Applicant), you theoretically could send that with your "instant" disclosures if you pull a credit report instantly and have the data. Otherwise, the exception notice has to be delivered "as soon as reasonably practical" and that may be earlier than your "Congratulations" letter. And again, as others have noted, I'd also recommend going with the exception notice for 1-4 secured loans -- much easier than the Risk-Based Pricing notice.
Good luck.
