Mortgage Preapproval Checklist: 10 Steps Before You Apply

Mortgage preapproval can give you a clearer idea of your potential financing before you start making offers on homes.

Preparation can also make the process easier. Before you apply, review your credit, understand your budget, organize financial documents and be ready to explain your income, assets and debts.

Use this 10-step mortgage preapproval checklist to get ready.

Key Takeaways

Prepare your credit, budget and financial documents before applying.
Compare multiple lenders rather than treating your first preapproval as your only option.
Remember that preapproval is conditional and does not guarantee final mortgage approval.

1. Decide Whether You’re Ready to Shop Seriously

You don’t necessarily need a mortgage preapproval when you’re casually researching home prices months before you plan to buy.

It becomes more useful when you’re preparing to tour homes seriously and potentially make offers.

A preapproval letter tells you that a lender is tentatively willing to lend up to a certain amount based on the information reviewed and assumptions made at that time.

It can also show sellers that you’ve already completed a preliminary financing review.

But the letter isn’t a guaranteed loan offer. Final approval still depends on underwriting, the property and other mortgage requirements.

2. Check Your Credit

Review your credit before a mortgage lender does.

Checking your own credit doesn’t lower your scores, and reviewing your reports ahead of time gives you an opportunity to identify inaccurate information or unfamiliar accounts.

Your credit can affect:

Which mortgage programs you qualify for
Interest rate and loan pricing
Mortgage insurance costs
The lender’s overall evaluation of your application

If you find an error, begin the dispute process rather than waiting until you’re already trying to get an offer accepted.

You don’t need perfect credit to qualify for every mortgage program, so avoid assuming that one particular score automatically determines whether you can buy.

3. Estimate a Monthly Housing Budget

Before asking how much a lender might approve, decide what monthly payment you’re comfortable carrying.

A complete housing budget can include:

Principal and interest
Property taxes
Homeowners insurance
Mortgage insurance, when applicable
HOA or condo fees
Maintenance and repairs

The maximum amount a lender is willing to finance and the amount you personally want to spend don’t have to be the same.

A home affordability calculator can help you model different home prices, down payments and monthly payments before you apply.

4. Review Your Debts and Debt-to-Income Ratio

Lenders consider your existing monthly obligations along with your qualifying income.

Common debts can include:

Credit card payments
Auto loans
Student loans
Personal loans
Other mortgages
Certain support obligations

Your debt-to-income ratio, or DTI, compares qualifying monthly debts with gross monthly income.

There isn’t one DTI limit that applies to every mortgage borrower. Loan program, underwriting findings and the rest of your financial profile can affect what is acceptable.

You can use a debt-to-income calculator to estimate where you stand before the lender performs its own calculation.

5. Decide How Much Cash You Want to Use

You don’t necessarily need a 20% down payment to get preapproved for a mortgage.

Conventional loans can permit down payments well below 20%, FHA financing can allow qualifying borrowers to put down 3.5%, and eligible VA and USDA borrowers may have zero-down-payment options.

A 20% down payment can still have advantages. On many conventional mortgages, an original loan-to-value ratio above 80% requires private mortgage insurance. But that doesn’t make 20% a universal preapproval requirement.

Think about how much cash you want to commit while preserving enough savings for:

Closing costs
Prepaid taxes and insurance
Moving expenses
Repairs
Emergency savings

If you’re building toward a target, a down payment savings calculator can help you estimate the monthly savings needed to reach it.

6. Gather Your Income, Employment and Asset Documents

Mortgage preapproval generally requires enough information for the lender to evaluate your ability to repay the loan.

Depending on your financial situation, that might include:

Recent pay statements
W-2 forms
Tax returns when required
Bank statements
Investment account statements
Employment information
Documentation for other qualifying income
Government-issued identification

The list isn’t identical for every borrower.

A self-employed borrower, commission earner or someone using rental income may need different records than a borrower earning a regular salary.

Fannie Mae’s current conventional guidelines, for example, allow employment income to be verified through borrower documents, the employer or approved third-party verification services.

Our guide to the five things you need for mortgage preapproval goes deeper into the information lenders typically review.

7. Don’t Assume a Job Change Automatically Disqualifies You

Employment history matters because lenders need to determine whether qualifying income is stable and likely to continue.

But the old rule of thumb that you must stay in the same job or career for two uninterrupted years is too simplistic.

For conventional mortgages, Fannie Mae says lenders generally evaluate the most recent two years of work history, but a shorter history can still be acceptable when positive factors support the income.

Frequent job changes also don’t automatically make income unusable if the borrower continues to demonstrate consistent and predictable earnings.

Self-employment has its own rules. A two-year earnings history is generally preferred, but Fannie Mae allows certain borrowers with less than two years of self-employment to qualify when they have at least 12 months in the current business and can document relevant prior experience and income.

If you’ve recently changed jobs, become self-employed or changed how you’re paid, tell the lender rather than assuming you need to postpone buying.

8. Avoid Unnecessary New Debt Before Applying

A new debt can affect both your credit profile and the monthly obligations used in mortgage underwriting.

If you’re planning to apply soon, consider delaying unnecessary applications for:

Auto loans
Personal loans
New credit cards
Retail financing

That doesn’t mean every recent credit account makes mortgage approval impossible.

It simply means a major financial change may require the lender to recalculate your qualification.

The same principle applies after preapproval. Avoid assuming your finances are locked in just because the lender issued a letter.

9. Compare Preapprovals From Multiple Lenders

You don’t have to use the first mortgage lender that preapproves you.

The Consumer Financial Protection Bureau recommends contacting at least three lenders for preapproval so you can compare loan options and pricing.

Different lenders can offer different:

Interest rates
Discount points
Origination charges
Lender credits
Mortgage programs
Service levels

Mortgage shopping does involve credit checks, but scoring systems account for borrowers comparing lenders.

CFPB currently says multiple mortgage credit checks made within a 45-day window are recorded as a single inquiry for scoring purposes.

Our guide to how mortgage preapproval affects your credit explains the rate-shopping rules in more detail.

10. Review Your Preapproval Letter and Keep Your Finances Stable

When a lender completes its preliminary review, it may issue a preapproval letter.

Read it rather than looking only at the maximum loan amount.

Check:

Maximum loan amount
Loan type, if specified
Assumptions or conditions
Expiration date
Whether additional documentation is needed

CFPB says preapproval letters commonly expire after about 30 to 60 days, although lender policies vary.

If your search takes longer, the lender may ask for updated financial information and issue a new letter.

Once you’re preapproved, avoid making significant financial changes without talking to your lender first.

That includes:

Changing jobs
Opening substantial new debt
Missing payments
Running up credit card balances
Moving large amounts of money without keeping documentation
Spending funds expected to be used at closing

What Happens After Mortgage Preapproval?

Once you’re preapproved, you can begin making serious offers within your budget.

If a seller accepts your offer, the mortgage process continues.

The lender still needs to evaluate the specific property and complete underwriting. That can involve:

Updated income and asset verification
Appraisal
Title review
Homeowners insurance
Property eligibility
Final credit and employment checks where applicable
Other loan conditions

Preapproval is an important step, but it isn’t the finish line.

Our broader guide to getting preapproved for a home loan explains what the letter means and what happens next.

Preapproval vs. Prequalification

Don’t put too much weight on the terminology alone.

Some lenders use “prequalification” for an early estimate based largely on information you provide and “preapproval” for a more thoroughly verified review.

Other lenders use the terms differently.

CFPB notes that lender processes vary widely, so the more important questions are what the lender actually reviewed and which conditions remain.

Our prequalification vs. preapproval guide explains the distinction.

Does Preapproval Guarantee You Can Buy a House?

No.

A preapproval letter says a lender is tentatively willing to lend up to a stated amount based on the information and assumptions reviewed.

It does not guarantee that:

Your offer will be accepted
The property will qualify
The appraisal will support the purchase price
Your finances will remain eligible
Final underwriting will approve the mortgage

That’s why it’s better to think of preapproval as a strong preliminary review rather than secured financing.

Mortgage Preapproval Checklist

Decide whether you’re ready to begin shopping seriously.
Review your credit reports and scores.
Set a realistic monthly housing budget.
Review your debts and estimate your DTI.
Decide how much cash you want to use for the purchase.
Gather income, employment and asset documentation.
Discuss recent job or income changes with the lender.
Avoid unnecessary new debt.
Compare preapprovals from multiple lenders.
Review your letter and keep your finances stable while house hunting.

Bottom Line

A strong mortgage preapproval starts before the lender pulls your credit.

Review your finances, determine what you’re comfortable spending, organize your documentation and understand any recent changes to your income or debts.

Then compare multiple lenders instead of treating your first preapproval as your only option.

Once you receive the letter, remember that it’s conditional. Keep your financial situation stable and stay in contact with your lender as you move from house hunting toward final mortgage approval.

FAQ

What should I do before getting preapproved for a mortgage?

Review your credit, estimate your housing budget and DTI, determine how much cash you want to use and gather documentation for your income, employment, assets and debts.

Do you need 20% down to get preapproved?

No. Many mortgage programs allow down payments below 20%, and eligible VA and USDA borrowers may qualify for zero-down-payment financing. Loan requirements depend on the mortgage program and borrower.

Do you need two years at the same job to get preapproved?

Not necessarily. Lenders evaluate employment and income stability, but conventional guidelines can allow shorter histories or job changes when the borrower’s income remains sufficiently documented and reliable.

Can self-employed borrowers get preapproved with less than two years in business?

Potentially. Fannie Mae generally prefers a two-year earnings history but permits certain borrowers with at least 12 months of current self-employment to qualify when additional requirements are satisfied.

How many lenders should you get preapproved with?

CFPB recommends getting at least three preapprovals so you can compare lenders, loan programs and potential pricing.

Does getting multiple preapprovals hurt your credit?

Mortgage inquiries can have a small effect on credit, but scoring systems account for rate shopping. CFPB says multiple mortgage credit checks within a 45-day period are recorded as a single inquiry.
