I agree with Curt. Generally speaking, the day the credit report is pulled is the valid date of the intial application. Whenever I pull credit, I will email or mail disclosures and keep an unsigned copy in my file until it becomes a signed application. Initial discolures don't need to be signed to be in compliance. They just need to be sent out to the applicant.
Stacey, as long as you have the a copy of the initial credit pull and unsigned disclosures dated the same day, you should be good to go for MDIA compliance.
