For applications (including preapproval requests) that did not result in an origination, enter the date when the final action was taken (e.g., the application was denied or the file was closed for incompleteness) or when the notice of the action was sent to the applicant..
If your policy is to close one day after the expiration then your loan officer owes you an explanation why it took them 30 days after the expiration to close the file.
