How to Get Pre-Approved for a Mortgage

A mortgage pre-approval is the single most useful thing you can do before you start house hunting. It tells you your real budget and signals to sellers that you are a serious, low-risk buyer. Here is exactly what it is and how to get one.

Pre-qualification vs. pre-approval

These two terms get used interchangeably, but they are not the same.

• Pre-qualification is a quick, informal estimate. You tell a lender your income and debts, and they give you a ballpark. No documents are verified.
• Pre-approval is the real thing. The lender pulls your credit, verifies your income and assets with actual paperwork, and issues a letter stating how much they are prepared to lend.

When a seller is weighing offers, a pre-approval letter carries real weight. A pre-qualification often does not.

What you will need

Gather these before you apply — having them ready makes the process fast:

• Proof of income: recent pay stubs (usually the last 30 days) and W-2s or 1099s for the past two years.
• Tax returns: the last two years, especially if you are self-employed or have variable income.
• Bank and asset statements: the last two to three months for checking, savings, and any investment or retirement accounts, to show your down payment and reserves.
• Identification: a government-issued ID and your Social Security number for the credit check.
• Debt details: the lender sees most of this on your credit report, but be ready to explain any large or recent changes.

If you are self-employed, expect more documentation and a closer look at your net income.

What the lender is actually evaluating

Lenders weigh a few core factors:

1. Credit score and history — higher scores unlock lower interest rates.
2. Debt-to-income ratio (DTI) — your monthly debt payments as a share of your gross income. Lower is better; many programs want your total housing-plus-debt load under roughly 43%.
3. Down payment and reserves — how much cash you are putting in and what is left afterward.
4. Employment stability — a steady two-year work history reassures lenders.

How long it takes and how long it lasts

Many lenders can issue a pre-approval within a few business days once you submit your documents. The letter is typically valid for 60 to 90 days, because your finances and credit can change. If your search runs longer, you simply refresh it.

Shop more than one lender

A pre-approval is not a commitment to use that lender. Rates and fees vary, sometimes significantly. Here is the part most buyers do not know: if you apply with multiple mortgage lenders within about a 45-day window, the credit-scoring models treat those inquiries as a single event, so rate-shopping does not meaningfully hurt your score. Get quotes from two or three and compare the rate and the lender fees.

Protect your approval until closing

A pre-approval can be undone. Between your approval and closing day, do not:

• Open new credit cards or finance a car — new debt changes your DTI.
• Make large, unexplained deposits or move money between accounts without records.
• Change jobs if you can avoid it, especially to a different field or to self-employment.
• Miss any payments.

Lenders often re-pull your credit right before closing. A new loan discovered at the last minute can sink the deal. The safest play is to keep your financial life boring from approval to keys.

The bottom line

Get pre-approved before you shop, gather your documents up front, compare a few lenders inside one short window, and then keep your finances stable until you close. Doing this turns a vague "I'd like to buy" into a concrete budget and a credible offer.
