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)

• Should give: realistic price range, likely rate band, clean documentation path, and a confidence level for offer timing.
• Should not give: false certainty that every property will qualify the same way or that monthly payment is fixed forever.

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.

Income

• Recent pay stubs (last 30 days)
• W-2s / 1099s (last 2 years)
• Full tax returns (last 2 years, if requested)
• Employment verification contact (HR/payroll)

Assets and cash

• Bank statements (2–3 most recent months)
• Brokerage/retirement statements if those funds are relevant
• Gift-fund documentation format (if applicable)
• Proof of source for large recent deposits

Debts and obligations

• Current monthly debt list (cards, auto, student, personal loans)
• Any support obligations or recurring non-credit commitments
• Property-related obligations if you already own real estate

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

• Do not open new credit lines before pre-approval unless necessary.
• Keep utilization stable/low; avoid large balance swings.
• Correct obvious report errors early, not during underwriting week.
• If DTI is tight, reduce a small recurring debt first; it can improve options more than expected.

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.

Pre-approval red flags (slow down if you see these)

• Payment quoted without tax/insurance context.
• Vague fee language with no structured estimate.
• Aggressive “you can afford this much” with no buffer discussion.
• Inconsistent guidance on gift funds / self-employment income handling.

Offer-readiness checklist (quick pass/fail)

• ✅ Document packet complete and dated
• ✅ Monthly payment stress-tested (base + higher-rate scenario)
• ✅ Cash-to-close + reserve buffer confirmed
• ✅ Two lender scenarios compared on same assumptions
• ✅ Closing timeline fits your actual move constraints
