What Documents Do You Need for a Mortgage Preapproval?
Before you even submit a full loan application, most mortgage lenders will offer a mortgage preapproval. This gives you a clearer picture of how much house you can afford and shows real estate agents and sellers that you’re serious.
But to get that preapproval letter, you’ll need to provide several key documents. Here’s what to expect:
Proof of Identity
One of the first steps in the application process is proving you are who you say you are. Lenders require a government-issued photo ID like a driver’s license, passport, or Social Security card to confirm your identity. This helps prevent identity theft and ensures you're legally allowed to apply for a mortgage loan.
It’s a simple part of the process, but don’t skip it, without this document, your home loan application can’t move forward.
Social Security Number
Your Social Security number gives the lender permission to run a full credit check. This includes reviewing your credit report, FICO credit score, credit history, and any outstanding debts.
This information helps the lender assess your financial habits and plays a big role in determining your eligibility, interest rate, and overall loan terms.
Proof of Income
Lenders want to know how much monthly income you bring in and whether it’s consistent. Your income directly impacts how much house you can afford and whether you’re likely to keep up with your monthly mortgage payments.
Showing a reliable stream of money reassures lenders that you’re financially ready for the responsibility of owning a new home.
W-2 Forms
Most lenders will ask for at least two years’ worth of W-2 forms from your employer. This helps confirm your total income and job stability. If you're applying with a spouse or partner, they’ll need to provide their W-2s too.
It’s a good idea to gather and organize these documents early so you’re not scrambling later in the process.
Tax Returns
In addition to W-2s, lenders usually require the past two years of tax returns. These documents offer a more complete view of your financial situation, including any side income, rental income, or business earnings.
For self-employed applicants, tax returns are especially important to verify total income and financial stability.
Bank Statements
Expect to provide at least two months of bank statements from both your checking and savings accounts. Lenders review these to verify that you have enough saved for the down payment, closing costs, and cash reserves after closing.
Your bank account activity can also show regular deposits and responsible money management, key factors in the application process.
Asset Statements
Lenders often ask for asset statements beyond just your bank accounts. This may include mutual funds, retirement accounts, and investment portfolios.
These documents give a more accurate view of your financial health and help confirm you can handle the full cost of your mortgage loan, even if unexpected expenses come up.
Credit Report Authorization
You’ll be asked to sign a credit report authorization form, which allows the lender to pull your credit. This step helps them understand your full credit profile, including past payment history, credit usage, and any current balances.
Your credit score is one of the biggest factors in loan approval and can directly impact your interest rate.
Proof of Employment
Most lenders will verify that you’re actively employed. That might include a written verification from your employer, a phone call, or recent pay stubs.
If you’re self-employed or an independent contractor, you’ll likely need to provide profit and loss statements, 1099s, or even tax returns.
Stable employment reassures lenders that your monthly income will continue well after you move into your new home.
Debt Information
You’ll need to list all current debts, including credit cards, student loans, car payments, and child support payments. This helps lenders calculate your debt-to-income ratio, which compares your monthly debts to your total income.
A manageable debt to income ratio shows lenders that you’re not overextended and are financially ready to take on a mortgage loan.
Rental History
If you’ve been renting, show that you’ve made on-time rent payments over the past 12 months. This could mean providing canceled checks, a letter from your landlord, or bank statements with clear payment history.
A solid rental record is especially important if you have limited credit history or you're applying for your first mortgage.
Gift Letters (If Applicable)
If a family member or close friend is helping you with the down payment, you’ll need a gift letter. This letter confirms the money isn’t a loan and doesn’t have to be paid back.
Even though it seems like a formality, lenders treat gifted money seriously, it must be clearly documented to stay compliant with official guidelines and keep your application process on track.
Common Mistakes to Avoid During Preapproval
Getting preapproved is a smart move, but even small slip-ups can slow down the mortgage process or result in a denial. Lenders rely heavily on the documents and financial information you provide, so attention to detail really matters.
Here are some of the most common mistakes to avoid while your home loan application is under review:
Submitting Incomplete or Outdated Documents
One of the most common delays happens when borrowers turn in old or missing paperwork. A tax return from several years ago or a bank statement that doesn’t include the latest month won’t give your lender what they need.
Make sure all your documents are current, complete, and meet the lender’s application requirements. Double-check that nothing’s missing before you hit submit, this small step can save you days of back-and-forth later.
Making Major Financial Changes Before Approval
Once you start the preapproval process, try to keep your financial situation steady. Changing jobs, making large transfers between accounts, or taking on a new car loan can affect how your lender views your assets, income, or debt-to-income ratio.
Any big change can raise questions and trigger a request for additional information, which can hold things up. If possible, wait until after your mortgage closes before making major financial moves.
Failing to Disclose Debts or Liabilities
It might be tempting to leave off a student loan, credit card, or child support obligation, especially if you think it could hurt your chances. But lenders will find it when they pull your credit report, and leaving it out could delay or damage your approval.
Be upfront about every debt, it helps your lender give you a realistic view of what you can afford and ensures a smoother review process.
Applying for New Credit During the Preapproval Process
You’ve probably seen store promotions offering a discount if you open a credit card at checkout. Don’t do it. Applying for new credit during preapproval can lower your credit score, increase your total monthly debt, and throw off your debt-to-income ratio.
Even small changes can raise red flags during underwriting. Hold off on any new credit activity until the deal is closed and the keys are in your hand.
What Happens After You’re Preapproved?
Once you're preapproved, you’ll receive a preapproval letter that shows sellers and real estate agents you're a serious buyer.
It’s a big deal, this letter proves your financial information has been reviewed, and your lender believes you're qualified for a mortgage loan based on your current assets, income, and credit profile.
But remember, preapproval isn’t a guarantee. You still need to complete the full loan application, go through underwriting, and provide any additional information your lender may request.
This next phase includes a home inspection, a deeper review of your documents, and a formal Loan Estimate that outlines your monthly payment, interest rate, and closing costs.
If everything checks out, you’re one step closer to final approval, and your new home.
How to Get a Mortgage Preapproval
Getting your documents in order might not be the most exciting part of buying a home, but it’s one of the most important.
The right paperwork gives your lender a clear picture of your financial health and helps move your mortgage application forward without delays. Once everything’s lined up, you’re in a much stronger position to get preapproved and make a solid offer.
