Mortgage applications are document-heavy. Lenders and brokers typically ask for proof of identity, proof of income, bank statements, details of debts and, for self-employed applicants, tax returns and accounts. Delays usually come from missing pages, unreadable scans or documents sent in the wrong format, not from the lending decision itself. Preparing your PDFs properly speeds things up.
Get the exact list from your lender or broker
Requirements vary by lender and country, and by your situation. Ask for the list in writing and check details such as:
- How many months of payslips and bank statements.
- Whether online statements are accepted or must be stamped or certified.
- Whether documents must show your full name and address.
- The upload method: a secure portal is common; ordinary email is not ideal for documents like these.
Download originals where possible
Statements and payslips downloaded as PDFs from your bank or payroll system are cleaner than scans of printouts, and lenders often prefer them because they are harder to alter. Download them directly rather than printing and scanning.
Scan paper documents properly
For anything on paper, use a scanner or a phone scanner app that crops and flattens the page. See scanning documents with your phone. Make sure every page is complete, with no cut-off edges.
Include every page
Lenders routinely reject statements with missing pages, even blank ones that say "this page intentionally left blank". Keep every page of each statement, in order, in one PDF. See how to combine PDF files.
Do not edit or annotate
Never change figures, dates or names on financial documents, and avoid highlighting or adding notes to the originals. Lenders check for alterations. If you want to explain something, such as a large deposit, write a separate short letter.
If you need to share a statement with someone who does not need all of it, such as a landlord, that is a different situation; see how to redact a bank statement before sharing. For a lender, send it whole.
Name files so they are easy to check
Use clear names: Payslip-2026-09.pdf, Bank-statement-Current-Account-Jul-Sep-2026.pdf, Passport.pdf. A broker checking dozens of files will thank you, and it reduces back-and-forth.
Keep sizes manageable
If the portal has a size limit, compress scanned PDFs, then check that every figure is still readable. Downloaded statements are usually small already. Docento.app can compress and merge files in the browser without uploading them, which suits documents that contain account numbers and income details.
Send securely
Use the lender's or broker's secure portal where offered. If you must email, ask about password-protected PDFs and share the password by another channel. See sending documents securely by email and how to password protect a PDF.
Takeaway
Get the exact list in writing, download originals rather than scanning printouts, include every page, never edit financial documents, name files clearly, and send them through a secure portal. A tidy document pack is one of the few parts of a mortgage application entirely in your control.
