Documents for mortgage preapproval: the complete packet

What the lender is trying to prove

Every document answers one of four questions. Can you repay, based on stable income? Do you have the money for the down payment, closing costs and any required reserves, from acceptable sources? What do you already owe? And are you who you say you are? Seen that way, the document list stops looking arbitrary.

Income documents

For salaried and hourly workers, lenders usually ask for recent pay stubs covering about a month and W-2 forms for the past two years. If your pay includes overtime, bonuses or commission, expect questions about how consistent it is, and possibly tax returns. Lenders may verify employment directly with your employer, often again shortly before closing.

Self-employed buyers usually need more: often two years of personal and business tax returns, a year-to-date profit and loss statement, and business bank statements. Start gathering these first, because they take the longest.

Other income such as alimony, child support, Social Security, pensions or rental income needs its own proof, such as an award letter, court order or lease and tax schedule.

Asset documents

Lenders verify that the money for your down payment and closing costs exists and comes from an acceptable source. Expect to provide recent statements, usually two months, for checking, savings and investment accounts. Send every page, including the pages that say "intentionally left blank."

Large deposits that are not your regular pay will draw questions. The lender needs to know where the money came from so it can rule out an undisclosed loan. Have records ready: a bill of sale for a car you sold, a transfer from your own brokerage account, or a gift letter and the donor's bank record.

Debt and credit

The lender pulls your credit report, which lists most debts. You may still need statements for loans that do not appear, explanations for late payments or collections, and documents for events such as bankruptcy or foreclosure. If you are divorced or separated, expect to provide the decree or agreement, which may show support obligations.

Renters may be asked for proof of rent payments, especially when a program considers rent history.

Gift funds

If family is helping, expect a signed gift letter stating the amount, the relationship, the property and that no repayment is expected, plus proof of the transfer from the donor's account to yours or to the closing agent. Each loan program sets who can give and how, so ask your lender for its form before money moves.

Sending documents safely

Use the lender's secure upload portal rather than email. Before uploading, rename files clearly, such as "Bank-Checking-March-2026," and combine multi-page statements into single files. Never send documents to a new address or portal that arrives by email without confirming it by phone with your loan officer at a number you already know.

After preapproval

Keep updating your packet. Lenders will want newer pay stubs and statements as the letter ages, and again during underwriting. When you apply formally, the lender must give you a Loan Estimate within three business days, and you can compare offers line by line. Keep your finances steady until closing, and tell your loan officer before any change.
