How to Get Pre-Approved for a Mortgage: Requirements and Timeline
Getting pre-approved for a mortgage is one of the most important steps before buying a home. Pre-approval shows sellers you’re a serious buyer and helps you understand exactly how much a lender is willing to loan you. This guide explains the requirements lenders look for, the documents you’ll need, and the realistic timeline for mortgage pre-approval in the USA—without vague assumptions or unnecessary steps.
Key Takeaways
- Mortgage pre-approval confirms how much you can borrow
- Lenders review credit, income, assets, and debts
- Pre-approval usually takes a few days to two weeks
- Strong pre-approval makes your offer more competitive
- Pre-approval letters typically expire after 60–90 days
What Mortgage Pre-Approval Actually Means
Mortgage pre-approval is a formal lender review of your financial profile. Unlike prequalification, which is an estimate based on self-reported information, pre-approval involves verified documentation and a credit check.
Cause → effect → outcome
Verified finances → stronger lender confidence → higher chance of offer acceptance.
Pre-approval does not guarantee final loan approval, but it significantly reduces surprises later.
Mortgage Pre-Approval Requirements Explained
Lenders focus on four core areas when you apply. Primary requirements:
- Credit score and credit history
- Income stability and employment history
- Debt-to-income (DTI) ratio
- Available assets and savings
Each requirement helps lenders assess your ability to repay the loan reliably.
Credit Score Requirements for Pre-Approval
Credit scores influence both approval likelihood and interest rates. Typical credit score ranges:
- FHA loans: ~580 minimum
- Conventional loans: ~620 minimum
- USDA loans: ~640 typical
- VA loans: lender-specific, often 620+
Higher scores generally lead to lower interest rates, which reduces monthly payments and lifetime interest costs.
Income and Employment Verification
Lenders want proof that your income is stable and ongoing.Common verification standards:
- Two years of consistent employment
- Recent pay stubs or income statements
- W-2s or tax returns for self-employed borrowers
Cause → effect → outcome
Stable income → predictable payments → lower lending risk.
Frequent job changes or commission-based income may require additional documentation.
Debt-to-Income Ratio (DTI) Requirements
DTI compares monthly debt payments to gross income. Typical DTI guidelines:
- Target maximum: 43%
- Some programs allow higher with strong credit
Lower DTI improves approval odds and helps ensure monthly payments remain affordable.
Documents Needed for Mortgage Pre-Approval
Having documents ready speeds up the process. Commonly required documents:
- Government-issued ID
- Recent pay stubs (last 30 days)
- W-2s or tax returns (last 2 years)
- Bank statements (last 2–3 months)
- Proof of additional assets or income
Incomplete documentation is the most common cause of delays.
Mortgage Prequalification vs Pre-Approval
These terms are often confused but not interchangeable.
Prequalification
- Informal estimate
- No document verification
- Not strong for offers
Pre-approval
- Verified financial review
- Credit check required
- Strong negotiating tool
In competitive markets, sellers often reject offers without pre-approval.
Mortgage Pre-Approval Timeline
Most borrowers complete pre-approval faster than expected.
Typical timeline
- Document collection: 1–3 days
- Lender review: 2–7 days
- Additional verification (if needed): up to 14 days
Total timeframe: usually 3–10 business days, though complex cases may take longer.
How Long Mortgage Pre-Approval Lasts
Pre-approval letters don’t last indefinitely.
Typical validity
- 60 to 90 days
- Credit and income may be rechecked
If your approval expires, lenders usually update documents rather than start over—unless your finances change significantly.
Common Mistakes That Delay Pre-Approval
- Changing jobs mid-process
- Making large purchases
- Opening new credit accounts
- Missing document deadlines
Avoid financial changes until after closing to keep approval intact.
