How to Get Pre-Approved for a Mortgage: A Step-by-Step Guide for Arizona Buyers

If you're serious about buying a home in Arizona, getting pre-approved for a mortgage isn't optional — it's the first real move you make. Sellers in Phoenix, Scottsdale, and the East Valley aren't going to take your offer seriously without one. And honestly, you shouldn't be writing offers without one either, because you don't actually know what you can afford until a lender runs the numbers.

The good news: getting pre-approved is a lot less painful than most people expect. Here's exactly how it works.

Pre-Approval vs. Pre-Qualification — They're Not the Same Thing

This is the one that trips people up constantly. Pre-qualification is basically a lender saying "based on what you told us, you might qualify for this amount." No documents checked. No credit pulled. It means almost nothing to a seller.

Pre-approval is different. A lender actually pulls your credit, reviews your income documentation, verifies your assets, and gives you a conditional commitment. That letter carries real weight. In a competitive market — and parts of Scottsdale and Chandler still move fast even as inventory opens up — a solid pre-approval letter can be the difference between getting your offer looked at and getting ignored.

When you're shopping around, ask specifically for a pre-approval, not a pre-qualification. They're not interchangeable.

What You Need to Get Pre-Approved for a Mortgage

Get this stuff together before you even talk to a lender. It makes the whole thing faster and you'll look like you know what you're doing — because you will.

Income Documentation

• W-2 employees: Last two years of W-2s, last two pay stubs, most recent tax returns
• Self-employed: Last two years of personal and business tax returns, a year-to-date profit and loss statement — it's more paperwork, but it's very doable
• Retired or on fixed income: Social Security award letters, pension statements, 1099s

Assets

• Last two months of bank statements (all accounts — checking, savings, investment)
• Retirement account statements if you're using them for the down payment
• Documentation of any gift funds if family is helping with the down payment

Credit and Debt

You don't need to pull your own credit — the lender will do that. But you should know roughly where you stand before you apply. A 620 gets you into most loan programs. A 680 opens up better rates. A 740+ and you're looking at the best pricing available. If your score needs work, that conversation is worth having before you apply so you have a real timeline.

ID and Other Basics

• Government-issued photo ID
• Social Security number
• Two years of residence history
• Two years of employment history

If you've recently changed jobs, don't panic. Lenders care about stability and income trajectory, not just length of time at one employer. A promotion in the same field is usually fine. Jumping industries right before applying is trickier.

What Happens During the Pre-Approval Process

Here's the actual sequence once you submit your application:

1. Application and document collection. You fill out a loan application (called a 1003 in the industry) and upload or send in your documents. At Pillar Mortgage Group, this can be done digitally — no need to fax anything to anyone in 2026.

2. Credit pull. The lender pulls a tri-merge credit report — that's all three bureaus (Equifax, Experian, TransUnion). They use the middle score. If you're applying with a co-borrower, they use the lower of the two middle scores. That's an important detail a lot of buyers don't know going in.

3. Review and underwriting. A loan officer looks at your full picture — income, debts, assets, credit — and calculates your debt-to-income ratio. This is one of the key numbers. Most conventional loans want your total monthly debt payments to stay under 43-45% of your gross monthly income. FHA can go a little higher in some cases.

4. Pre-approval letter issued. If everything checks out, you get a letter showing the maximum loan amount you're approved for, the loan type, and the rate environment it's based on. This letter is usually good for 90 days.

The whole process typically takes 1-3 business days when you have your documents ready. If you're disorganized about it, it can stretch to a week or more.

What Can Kill Your Pre-Approval After You Get It

This part matters a lot. Getting pre-approved isn't the finish line — you have to keep your financial picture stable until the loan closes. Here's what not to do:

• Don't open new credit accounts. New credit = hard inquiry + new debt = potential change to your debt-to-income ratio. Even a new credit card with a zero balance can ding your score temporarily.
• Don't make large unexplained deposits. Lenders will ask about any big deposits in your bank account. If you're getting gift money, document it properly with a gift letter.
• Don't quit your job. This one sounds obvious, but it happens. Lenders verify employment right before closing.
• Don't finance a car or appliances. New installment debt can push your DTI over the limit and tank an otherwise solid pre-approval.
