Mortgage Preapproval: What Documents Do You Need?

Written and reviewed by Kladi Bejkolli Mortgage Loan Officer, NMLS #1626841 Last reviewed September 30, 2026

The straight answer

Preapproval usually comes down to three buckets of paperwork: proof of income, proof of assets, and identification. The exact list varies by lender and by situation, but if you have those three covered, you are most of the way there. A preapproval is not a guarantee of final approval, but it is the strongest way to start: it tells you what you can borrow and shows sellers you are a serious buyer.

Why preapproval matters

A preapproval does two things at once. It tells you what you can actually borrow, based on a lender's review of your income, assets, and credit, so you shop with a real number instead of a guess. And it shows sellers you are serious: in a competitive market, an offer backed by a preapproval letter carries more weight than one without it. The CFPB explains the difference between a prequalification letter and a preapproval letter in plain language: a preapproval is built on verified documentation, not just the numbers you report yourself.

One honest caveat: a preapproval is not a guarantee that the loan will close. Final approval comes later, after underwriting reviews your full file and the property itself is part of the picture. But it is the strongest way to start, and it is the step that turns a wish list into a plan.

The income bucket: proving what you earn

The income bucket proves what you earn, and lenders want to see it from more than one angle. For most employees that means your most recent pay stubs, typically the last two months, plus W-2s for the last two years. Tax returns round out the picture, and that is where the list usually grows: if you are self-employed, or if a meaningful part of your income comes from bonus, commission, or overtime, lenders typically want extra history, usually two years of tax returns, to show the income is consistent and likely to continue.

Fannie Mae's guide to the documents you need to apply for a mortgage walks through the same list in plain language, including how self-employment income is documented. The pattern is simple: the more complex your income, the more history lenders ask to see.

The assets bucket: showing your down payment and closing costs

The assets bucket shows you have the cash for your down payment and closing costs, and that the money is yours. Lenders ask for recent bank statements, and investment statements if you plan to use brokerage funds, to confirm the funds exist and to trace where they came from. The exact statement period varies, but recent statements, typically the last two months, are the common ask.

If part of your down payment is a gift from family, lenders need a gift letter: a signed statement that the money is a gift and not a loan that would add to your debt. The letter is a simple form your lender provides, and it is the difference between a clean file and a long round of questions.

Identity and the basics

Every application starts with identification: a valid government-issued ID, like a driver's license or passport, so the lender can confirm who you are. From there, the list depends on the loan program and your situation. Some programs ask for additional forms, and your lender may request extra items based on how your income is structured or where the property is. The CFPB lists the core information every mortgage application needs, and the CFPB's preapproval guide notes that lenders differ in what they request, so asking is always fair game.

None of this is a test. It is the lender building a complete, verifiable picture of your application, and your loan officer should tell you exactly what your program needs before you gather anything.

Getting organized: how to make it easy

Most of the friction in preapproval comes from hunting for documents at the last minute, not from the documents themselves. Gather the last two years of tax returns and recent statements now, before you start, and keep them in one place. Digital copies are fine: lenders are used to receiving clear scans or photos.

One habit to avoid: do not move money between accounts right before you apply. Large transfers and new deposits raise questions about where the funds came from, and lenders have to verify them, which slows the process down. Keep your accounts where they are while you shop.

And when in doubt, ask. A good loan officer will hand you a list of exactly what they need for your situation, which is a much better guide than any general article.

The preapproval checklist

Here is the short version, ready to scan on your phone. Check off what applies to you:

  • A valid government-issued ID

    Driver's license or passport, to confirm who you are.

  • Pay stubs

    Typically the last two months, to prove current income.

  • W-2s

    Typically the last two years, for most employees.

  • Tax returns

    Typically the last two years, especially if you are self-employed or rely on bonus, commission, or overtime.

  • Bank statements

    Recent statements for the accounts holding your down payment and closing costs.

  • Investment statements

    If you plan to use brokerage or retirement funds toward the purchase.

  • Gift letter

    If part of your down payment is a gift from family. Your lender provides the form.

This is a typical list, not a universal one: programs and lenders vary, and your loan officer will confirm exactly what your situation needs.

Key takeaways

  • Preapproval paperwork falls into three buckets: proof of income, proof of assets, and identification. Cover those and you are most of the way there.
  • Income documentation grows with complexity: self-employed borrowers, and anyone relying on bonus, commission, or overtime, typically need two years of tax returns.
  • Do not move money between accounts right before applying. Lenders verify where down payment funds come from, and large new deposits slow things down.
  • A preapproval is not a guarantee. Final approval comes after underwriting, and the property itself is part of the review.

Frequently asked questions

How long is a preapproval good for?

Usually 60 to 90 days, but it varies by lender and program, and it depends on how much has changed in your file. When a preapproval expires, it is not a rejection: your loan officer can refresh it with updated documents and a new credit pull. Ask at the start how long your letter is valid so you can time your home search around it.

Does a preapproval guarantee the loan?

No. A preapproval is a strong starting point, but final approval comes after underwriting reviews your full file, and the property is part of it: the appraisal, the title review, and the property's condition all factor in. That is normal, and it is why a preapproval is a plan, not a promise.

Can I get preapproved if I am self-employed?

Yes. Expect to document more: lenders typically want two years of tax returns for self-employed borrowers, and they may ask for additional records depending on how your business is structured. The exact list depends on the lender and the program, so ask your loan officer what your situation requires before you gather anything.
