Why Pre-Approval Matters
Getting pre-approved for a mortgage is one of the first steps in buying a home. A pre-approval letter tells sellers you are a serious buyer. It shows that a lender has reviewed your finances and is willing to lend you up to a certain amount.
In a competitive market, sellers often will not consider offers without a pre-approval letter. Getting pre-approved before you start shopping also tells you exactly how much home you can afford, so you do not waste time looking at homes outside your budget.
Pre-Qualification vs. Pre-Approval: Know the Difference
These two terms are often confused. They are not the same thing.
| Feature | Pre-Qualification | Pre-Approval |
|---|---|---|
| Credit check | Soft pull or none | Hard pull |
| Documents verified | No | Yes |
| How strong it is | Weak estimate | Strong commitment |
| Time to complete | Minutes | 1 to 3 days |
| Seller confidence | Low | High |
Always aim for a full pre-approval, not just pre-qualification. Sellers and real estate agents know the difference.
What You Need to Get Pre-Approved
Lenders will ask you to provide documents that prove your income, assets, and identity. Gather these before you start the process to speed things up.
Income Documents
- W-2 forms from the last 2 years
- Federal tax returns from the last 2 years
- Recent pay stubs (last 30 days)
- If self-employed: 2 years of tax returns plus a profit and loss statement
Asset Documents
- Bank statements from the last 2 to 3 months (all accounts)
- Investment account statements
- Retirement account statements
- Gift letter if you are receiving down payment help from family
Debt Information
- Statements for any existing loans (auto, student, personal)
- Credit card statements
- Any other monthly obligations
Identity Documents
- Government-issued photo ID (driver’s license or passport)
- Social Security number
What Lenders Look At
Lenders evaluate four key areas when reviewing your pre-approval application.
1. Credit Score
Your credit score is one of the first things a lender checks. Here are the minimums for common loan types:
| Loan Type | Minimum Credit Score |
|---|---|
| Conventional | 620 |
| FHA | 580 (3.5% down) or 500 (10% down) |
| VA | 580 to 620 (lender-set) |
| USDA | 640 (lender-set) |
A higher score gets you better rates. Moving from 620 to 740 can reduce your mortgage rate by 0.5% or more, saving tens of thousands over the life of the loan. See our full guide on how to improve your credit score if you want to boost it before applying.
2. Income and Employment
Lenders want to see steady income. Most require 2 years of employment history in the same field. If you recently changed jobs, that is usually fine as long as you stayed in the same industry.
Self-employed borrowers face more scrutiny. Lenders average your last 2 years of net income from tax returns. Recent income increases may not count if your tax returns do not reflect them yet.
3. Debt-to-Income Ratio
Your DTI is your total monthly debt payments divided by your gross monthly income. Most conventional lenders want a back-end DTI under 43%. FHA and VA can go higher with strong compensating factors.
A lower DTI means more loan options and better rates.
4. Down Payment and Assets
Lenders want to see that you have enough for the down payment plus closing costs. They also want to see reserves, meaning money left over in your accounts after closing. Two to three months of mortgage payments in savings is a common requirement.
Soft Pull vs. Hard Pull: What Happens to Your Credit
Pre-approval requires a hard inquiry on your credit. This can drop your score by 2 to 5 points temporarily.
If you shop multiple lenders for the best rate, do it within a 14 to 45 day window. Credit scoring models treat multiple mortgage inquiries within that window as a single inquiry. This protects you when rate shopping.
How to Get the Best Pre-Approval
Step 1: Check and improve your credit before applying. Pull your free report from AnnualCreditReport.com. Dispute any errors. Pay down credit card balances if possible. Give yourself 30 to 60 days to boost your score if you have time.
Step 2: Calculate your budget. Use a mortgage calculator to estimate your monthly payment. Factor in property taxes, homeowners insurance, and HOA fees in addition to principal and interest.
Step 3: Gather your documents. Prepare everything on the document list above before you contact any lender. Having documents ready speeds up the process significantly.
Step 4: Shop at least 3 lenders. Rates and fees vary more than most buyers realize. Getting quotes from 3 or more lenders can save $1,000 or more over the life of the loan.
Step 5: Submit your application. The lender will pull your credit, verify your documents, and issue a decision. This usually takes 1 to 3 business days.
Step 6: Receive your pre-approval letter. The letter specifies the loan amount, loan type, and expiration date. Share it with your real estate agent and include it with any offers.
How Long Does Pre-Approval Last?
Most pre-approval letters are valid for 60 to 90 days. If your letter expires before you find a home, contact your lender to renew it. They may need updated pay stubs and bank statements.
What Can Kill a Pre-Approval
Getting pre-approved is not a guarantee your loan will close. Several things can cause problems between pre-approval and closing.
- Taking on new debt: Do not buy a car, furniture, or take out any loans while under contract.
- Job loss: Losing your job after pre-approval can make the loan fall through.
- Large unexplained deposits: Lenders will ask about big deposits in your bank account. Document the source.
- Credit score drop: Maxing out a credit card or missing a payment after pre-approval can cause problems.
- Property issues: If the appraisal comes in low or the home has major defects, the loan may not close as expected.
