Mortgage pre-approval checklist (U.S.)

This guide is for first-time buyers who want to avoid the usual pre-approval chaos: missing files, inconsistent lender answers, and budget surprises right before offer time. Use it as a practical workflow, not just a doc list.

What pre-approval should give you (and what it should not)

Stage 1 — Baseline affordability before lender outreach

Do this first so you compare lenders from a position of clarity.

  1. Define your monthly housing cap using total payment, not principal+interest only: PITI + PMI + HOA + baseline maintenance.
  2. Estimate cash-to-close separately from down payment. Include lender fees, title/settlement, prepaids, and local taxes/recording items.
  3. Protect a post-close emergency buffer (typically 3–6 months of essential housing costs).

Stage 2 — Document package (clean and lender-ready)

Prepare one folder per category so submissions are fast and consistent across lenders.

Assets and cash

Debts and obligations

Stage 3 — Credit and DTI cleanup (2–6 weeks before applying)

Stage 4 — Lender comparison workflow (apples-to-apples)

  1. Send the same profile packet to each lender in a short window.
  2. Request comparable outputs: estimated rate, points, lender credits, APR context, and close timeline.
  3. Track responses in one comparison sheet, not in chat/email fragments.
  4. Ask explicitly: lock options, extension costs, and document turn-times.
