If the applicant has not identified a property, are the 3 day disclosures still required?

RESPA only applies once a property has been identified.

I have a situation this morning applying to a preapproval. I am uneducated in this situation b/c we don't usually do preapprovals at my bank. The loan officer had the applicant fill out an application and preapproved it. Application was received in the first week of April. Today, I'm sending out the 3-day disclosures since the applicant came in yesterday and identified a subject property. Now my disclosures will be over two weeks difference than the application. Do I need a new signed application or am I ok since its a preapproval

You don't need a new app, just document the date the property was identified to the bank and base your 3-day disclosures on that date.
