For you first item, I think it still stands to reason that an application for a preapproval should get the disclosure, at least for our shop as that application serves as our sole application for the purchase, and you know the eventual loan will be secured by a 1-4 family.
Waiting for a property address is simply semantics at that point and nothing about the property would influence the appraisal disclosure, as it certainly could the LE, hence why it would not be prudent to send an LE without knowing the specifics about the property. But I digress.
To answer your question, the rulemaking makes no provision not to send it out if denied or withdrawn within the first three days. An oversight IMO. That said, when I review a denied or withdrawn within three day file, as long as see a copy of the disclosure there, then I assume it has gone out with the denial or withdrawn notice as per the rule stands.
