What's the First Step to Getting Pre-Approved? (and What's the Difference Between Pre-Qualified and Pre-Approved?)

by Brian Wittman

You want a clear first step. One thing to do this week that moves you toward a house, in the right order, without wasting a credit pull or a weekend.

Here's what you may not realize. The first step you get told depends on who you ask.

Picture two numbers on the same kitchen table. The bank says you can carry $2,825 a month. Your real life, after daycare, the car and what you're saving, says $2,370. That's a $455 a month gap, or $5,460 a year, and nobody in the transaction is paid to point it out.

What's the first step to getting pre-approved?

The first step is deciding your own monthly number before anyone hands you theirs, and it's the one almost nobody tells you about. Start with your take-home pay, subtract your fixed bills, what you really spend and what you save, and see what's left for the whole house payment. Then check your own credit and gather your documents. Then apply with a lender, or better, two or three. The pre-approval comes third. It isn't wrong to get one early. It's just mislocated when it comes first.

Why does everyone tell you a different first step?

Because everyone's answering from the chair they sit in.

Some agents will tell you to find an agent first. That's how they become your agent. Other agents will tell you to get pre-approved first, because they don't want to spend weekends touring with someone who can't buy. Loan officers will tell you to get pre-approved, because that's how they become your lender. And the average lender's website will tell you to check your credit score first.

None of them are wrong, exactly. Your credit really does shape your rate and your options, and you should check it before anyone else pulls it. You can see all three of your reports free at AnnualCreditReport.com, and looking at your own report doesn't touch your score.

None of them are lying, either. And look, I sit in both of those chairs. I'm a licensed agent and a loan officer, so I've said every one of those lines.

Now, here's the part that gets skipped. A pre-approval tells you the most a lender will let you borrow. It doesn't tell you the number that fits your life and leaves you breathing room. They're two different numbers, and only one of them is yours.

So when someone tells you to start with them, it's fair to ask what they'd want to know about you first. The answer tells you a lot about how to interview a real estate agent before you sign anything, and the same goes for how to interview a loan officer.

How do you figure out your own number?

You work backward from the money that actually reaches your account, not from your gross pay.

Start with take-home pay. It's what lands in your account, not your salary. If your overtime moves around, use the number you can count on in a slow month.
Subtract your fixed bills. Car payment, student loans, childcare, phone, insurance, subscriptions.
Subtract what you really spend. Groceries, gas, kids' sports, a night out. Be honest here, because the house won't make these go away.
Subtract what you save. Retirement, an emergency fund, and a cushion for the furnace that dies in February.
What's left is your housing number. That's principal, interest, property taxes, insurance and any PMI or HOA, all in.

That last line's the one that matters most out here. Will County property taxes commonly run 2 to 3% of a home's value a year, so the tax line alone can be several hundred dollars of your payment. Plug your county and its tax rate into how much home you can comfortably afford and you'll see your number with taxes in it, not without them.

That's the whole idea behind knowing what you're approved for versus what you can actually afford. The letter answers how much they'll lend you. Your number answers how much you should borrow.

What documents do you need to get pre-approved?

You'll get asked for the same core list by almost every lender. The Consumer Financial Protection Bureau's loan application checklist covers:

Pay stubs for about the last 30 days
W-2s for the last two years
Federal tax returns for the last two years
Your two most recent bank statements
Proof of where the down payment's coming from, or a gift letter
A photo ID and your Social Security number

If you work overtime, shift differential or a second job, expect more questions. Fannie Mae generally wants to see about a two-year history before that income counts, though less can work in some cases, and the rules differ by loan program. Here's how lenders actually count overtime income, and it's worth knowing before you apply, not after. Verify the details with your lender.

Does getting pre-approved hurt your credit?

It can, a little, and only once if you're smart about timing.

Most lenders still use a FICO score today. Some have started using VantageScore 4.0, which Fannie Mae and Freddie Mac opened to all approved lenders on September 9, 2026. That matters because the two models treat rate shopping differently. Newer FICO models count multiple mortgage credit checks within 45 days as one. VantageScore uses 14 days.

You won't always know which one your lender uses. So the safe move is simple: do all your lender shopping inside about two weeks. Worst case scenario, every pull lands inside both windows and counts once.

Some lenders run a soft check for a pre-qualification and a hard pull for a pre-approval. Others pull hard from the start. Ask before you hand over your Social Security number. Lenders also still pull all three credit bureaus, so a problem on any one report counts.

What's the difference between pre-qualified and pre-approved?

Less than you'd think, and it depends on the lender. The CFPB says plainly that lenders use the two terms differently, and neither one is a guaranteed loan offer.

Generally, a pre-qualification's based on what you've told the lender. A pre-approval's based on what they've checked: your credit, your pay stubs, your bank statements. So don't ask which word is on the letter. Ask what they actually verified.

What does a pre-approval letter actually tell you?

It's telling you the ceiling. It isn't telling you the target.

A seller's agent reads your letter as proof you can close. That's useful. Just don't let the bank's ceiling become your budget by default, because the house you buy at the top of that range is the payment you'll make for years.

Two more things worth knowing. How long a pre-approval stays good varies by lender, so ask yours. And once you give a lender six pieces of information (your name, income, Social Security number, the property address, an estimated value and the loan amount), federal rules require a Loan Estimate within three business days. That's a standard form, so you can lay two side by side and compare real offers.

It's worth doing. Freddie Mac's 2018 research found borrowers saved about $1,500 on average by getting one extra quote, and about $3,000 with five.

Get the order right and the next five to ten years in that house get easier, because the payment fits the life instead of the other way around. It's the same order every step of buying a house in the Chicago suburbs follows: money first, map second, house third.

The Bottom Line

The first step to getting pre-approved isn't the pre-approval. It's your own number. Work it from your take-home pay, put the real tax bill in it, and walk into the lender's office already knowing what fits.

Then gather the paperwork, shop two or three lenders inside about two weeks, and compare Loan Estimates side by side. The letter's still worth having. It just answers a different question than the one you're trying to answer.

Frequently Asked Questions

What is the first step to buying a house?

Decide your own monthly payment number from your take-home pay, before any lender gives you theirs. Then gather your documents and get pre-approved. Picking a town and touring homes come after the money is settled, so you don't fall for a house you can't comfortably carry.

How long does it take to get pre-approved?

Often a day or two once a lender has your documents, though it varies by lender and by how complicated your income is. Overtime, self-employment or a recent job change can add questions. Having your pay stubs, W-2s, tax returns and bank statements ready is what speeds it up.

Does a pre-approval hurt your credit score?

A hard pull can drop your score a few points. If you shop several lenders, do it within about two weeks, because newer FICO models treat mortgage pulls within 45 days as one and VantageScore uses 14 days. Ask each lender whether they run a soft or hard check first.

Is pre-qualified the same as pre-approved?

Not always. Lenders don't all use the terms the same way. Generally a pre-qualification's based on information you report, and a pre-approval is based on information the lender has verified. Ask what they checked rather than trusting the label.

How much house can I afford?

Start from take-home pay, subtract your fixed bills, real spending and savings, and what's left is your monthly housing number, with taxes and insurance included. That's often less than a lender will approve, and the difference is your breathing room.

If you're pre-approved, are you guaranteed the loan?

No. A pre-approval isn't a final approval. The loan's still got to clear underwriting, the house has to appraise, and your income, debts and credit have to hold steady until closing. A new car loan or a job change in the middle can change the answer.

Should I get pre-approved before talking to a real estate agent?

You can talk to an agent any time, and a good one will ask about your number before your wish list. Just know your own payment number before either conversation, because then you're the one setting the price range, not the letter.

If somebody told you a different first step and you want to know why, tell me what they said and I'll walk you through where it fits.

Set up a time if you want to work out your own monthly number, with real Will or Cook County taxes in it, before any lender hands you theirs.
