If I upload a document once, does it fill in across all the lender applications?

Yes. You fill out and upload to one master application, and that data carries into the separate application Levr creates for each lender you select. So you are not re-entering the same client information or re-uploading the same documents for every lender. When you submit to multiple lenders, autofill populates each lender's specific form from the master data, and the required documents attach automatically. One upload, packaged for every selected lender.
