Timing of your letter asking for verification is flexible, as long as you don't delay issuing the Loan Estimate. That's all the regulation says about it. Put another way, you cannot require the verifying documents, etc., before issuing the LE.
A lot of banks include their punch list of required documentation as part of the cover letter that accompanies the LE (as you put it, "with the Earlies"), along with instructions on how to provide the intent to proceed and how much in fees will need to accompany the intent to proceed before you continue processing the application.
Yes, you can still pull credit and ask for a payment to cover the bona fide cost of the credit report before sending the LE and before getting intent to proceed. But that's the only cost you can impose before getting intent to proceed. You can require the credit report fee(s) to be paid with the application, if you wish.
Verification is what you make it. You need to support the information on the application so that you can underwrite the loan.
