How to Interview a Loan Officer (and What Questions to Ask a Mortgage Lender)

by Brian Wittman

You'll get the questions to ask before you pick a lender, what a good answer sounds like, and how to compare the offers you get back. It usually takes one or two phone calls, and it's the cheapest homework you'll do in the whole purchase.

Here's what you may not realize. Two lenders can quote you the same loan program and still want very different things from you. One counts your overtime. The other doesn't. That's the same house and the same income turning into two very different approvals.

What questions should you ask a loan officer?

Ask how they'd count your income, what their own minimums are, what monthly payment they'd put you at, how long their files are taking right now, and who you'll talk to when something comes up. Then ask for a Loan Estimate. Those answers tell you more than any rate quote does, because they show you how the loan will actually be built around your life and your paycheck.

How do you know if a loan officer is any good?

Start with the license. Every mortgage loan officer has an NMLS number, and you can look it up yourself on NMLS Consumer Access by name or ID. In about a minute, you'll see whether they're licensed in Illinois and which company they work for.

After that, it comes down to the questions. A good loan officer asks about your life before they ask for a single one of your documents. They want to know what you do, how you get paid and what payment feels comfortable. The average lender opens the conversation with the maximum you qualify for. A good one opens with you. Notice which one you got.

How will you count my income?

This is the question that matters most if your pay moves from check to check. Overtime, shift differential, bonus and side work can all count, but lenders usually want a track record and they'll often average it. Some lenders count more of it than others, and that difference can move your approval by a lot.

So ask it plainly and directly. "Here's how I get paid. How much of it would you count?" Then listen for specifics, because a vague answer on that first call turns into a surprise later in underwriting. If you work shifts, it's worth knowing how lenders count overtime income before that call, so you can tell a real answer from a guess.

What are your own minimums and overlays?

Every loan program has its own set of rules for credit, income and debt. Lenders are allowed to add stricter rules on top, and those extra rules are called overlays. That's why one lender says yes to a file another lender turns down.

Ask what their minimum credit score is for the loan you want, and whether they add anything on top of the program. You'll learn fast whether you're a fit. That's the point. And since your credit score changes your rate, not just whether you qualify, ask how your score would price.

What monthly payment would you put me at?

Here's how I'd look at it. The approval amount is the most a lender is willing to lend you, and it is not the payment you should plan your life around.

So ask for the payment, not the maximum. Ask them to include property taxes, insurance and any mortgage insurance, because that's the real number you'll pay every month. A loan officer who'll build the loan backward from your payment is worth more to you than one who just hands you a ceiling. That gap between what you're approved for and what you can actually afford is where people get stretched thin.

How long are your files taking right now?

Turn times change with the season and with each lender's workload, so ask how long it's taking them right now to get from application to clear to close.

It's one of the fairest questions you can ask, and the answer shapes how long it takes to close on a house. If their timeline does not fit your contract dates, you'd rather know that before you sign anything. Ask now.

Who will I actually talk to when something comes up?

Ask who answers the phone after the application goes in. Is it the loan officer, a processor or a call center? None of those answers is wrong. It just matters. You just want to know before the week your underwriter asks for a document on a Friday afternoon.

Ask how they will keep you updated, too. A weekly check-in, even when nothing is new, is a good sign about how the rest of the file will go.

How do you compare Loan Estimates from different lenders?

Ask each lender for an official Loan Estimate on the same loan, same day if you can. The CFPB says comparing one against Loan Estimates from other lenders is the best way to tell whether you've got a competitive offer.

Line them up side by side and look at the rate, the points, the lender fees and the cash to close. A lower rate that comes with points isn't always the cheaper loan, and knowing how interest rate buydowns work helps you see which one actually costs less over the years you'll own the house.

Does talking to more than one lender hurt your credit?

Not much, as long as you keep your shopping inside a short window. The CFPB says multiple credit checks from mortgage lenders within a 45-day window are recorded on your credit report as a single inquiry. So shopping two or three lenders inside that window costs you about the same as shopping one.

That's why it pays to have your documents ready before you start. When you're getting pre-approved, a short, organized round of calls beats a slow one that drags past the window.

The Bottom Line

Interviewing a loan officer isn't about finding the lowest number on a website. It's about finding the person who will build the loan around your life. Ask how they'll count your income, what their own minimums are, what payment they'd put you at, how long they're taking and who you'll talk to. Then compare Loan Estimates side by side. Pick the person, not the ad.

The right loan on the right house makes the next five to ten years a lot easier. The wrong one makes every month a little tighter.

Frequently Asked Questions

How many lenders should I talk to?

Two or three is plenty for most people, which is enough to compare real Loan Estimates without dragging your search past the CFPB's 45-day window for credit checks.

What's the difference between a loan officer and a lender?

The lender is the company that funds or arranges your loan. The loan officer is the licensed person you work with there. You can look up both on NMLS Consumer Access.

Should I just use my bank?

You can, and sometimes your bank is a great fit. Just ask your bank the same questions you'd ask anyone else, and compare its Loan Estimate against at least one other lender's.

Is the lowest rate always the best deal?

No. Points, lender fees and how long you'll keep the loan all change the math. Compare the full Loan Estimate, not just the rate.

What should I have ready for the first call?

Know how you get paid, roughly what you've saved and the monthly payment you're comfortable with. Your lender will tell you which documents they need when it's time to apply.

When should I talk to a loan officer?

Before you start touring houses, because you will want your real number in hand before you fall for a kitchen.
