Mortgage pre-approval document stack: W-2s, pay stubs, bank statements, and IDs

Overview

Lenders verify that your income is stable, your assets are sourced, and your credit profile supports the loan. Sending complete, recent PDFs (all pages) prevents delays.

Good rule: if a document mentions “Page 1 of 6,” upload all 6 pages—even if some are blank.

Income & employment

Typical requests

  • W-2 or 1099 (last 2 years)
  • Recent pay stubs covering 30 days
  • Most recent YTD pay summary if variable overtime/bonus
  • Offer or transfer letter (if changing jobs)

Pro tips

  • Download PDFs from the payroll portal (avoid photos of paper stubs).
  • Make sure names/SSN fragments match your application.
  • Flag any gaps in employment over 30–60 days.

Self-employed & variable income

  • Personal & business tax returns (most recent 1–2 years)
  • Year-to-date P&L and balance sheet (if requested)
  • 1099 statements and proof of continuing contracts
  • Business bank statements (2–3 months)

Note: Deposits used as down payment may need to be from personal funds; moving money from business to personal can trigger extra documentation.

Assets & reserves

What to upload

  • Checking/savings statements (last 2–3 months)
  • Retirement statements (latest quarterly/monthly)
  • Stock/brokerage statements

What underwriters look for

  • Enough funds for down payment + closing costs
  • Reserves (months of PITI) if required
  • Large deposits with explanations & proof of source

Gift funds

  • Completed gift letter (lender’s template)
  • Evidence of donor’s ability (their statement) if required
  • Proof of transfer: donor → your account (and to escrow if applicable)

Avoid cash. Use clear transfers and keep records. Ask your loan officer for the exact gift letter format.

IDs & other items

  • Government photo ID (valid, unexpired)
  • Social Security card (if requested)
  • Visa/green card docs for non-US citizens (program dependent)
  • Rental history or VOE (verification of employment) as applicable

Source-of-funds “paper trails”

Any large or unusual deposits must be explained and documented. Paper trails should show where money came from and how it reached your account.

Examples that need a trail

  • Transfers between your own accounts
  • Reimbursement from a friend/family
  • Sale of an asset (car, crypto, collectibles)

Good trails include

  • Statements from both sides of a transfer
  • Bill of sale + proof of payment for asset sales
  • Gift letter + donor evidence + transfer receipt

Common pitfalls & quick fixes

  • Photos of documents: replace with native PDFs.
  • Missing pages: upload full statements (all pages).
  • Cash deposits: avoid; they’re hard to source.
  • Moving money late: consolidate earlier; keep funds steady once you apply.
