What pre-approval actually is

Pre-approval is a lender's written statement that they will loan you up to a certain amount of money, based on information you've given them about your income, debts, and credit. It is not a promise to lend — it's a conditional yes that depends on the house you choose and what the lender finds when they verify everything you told them.

Pre-approval is different from pre-qualification, which is what a lender tells you over the phone or online without checking anything. Pre-qualification takes five minutes. Pre-approval takes a week or two and involves real paperwork: tax returns, pay stubs, bank statements, and a hard pull of your credit report.

When you have a pre-approval letter in hand, you can make an offer on a house knowing roughly what you can afford, and the seller knows you're serious because a lender has already looked at your finances. This letter is what real estate agents mean when they say "get pre-approved before you start looking."

Key Takeaways

  • Pre-approval requires you to submit tax returns, recent pay stubs, and bank statements so the lender can verify your income and debts.
  • The lender will pull your credit report and calculate how much they will lend based on your debt-to-income ratio, which compares your monthly debt payments to your gross monthly income.
  • Pre-approval is conditional — the lender will verify everything again once you choose a house, and the deal can fall through if your financial situation changes or the house appraises for less than the purchase price.
  • Pre-approval letters are usually valid for 60 to 90 days, and you will need a new one if you wait longer or if your finances change significantly.
  • Getting pre-approved does not lock you into one lender — you can shop around and compare offers from multiple banks or mortgage companies.

What lenders look at when they decide how much to lend you

Lenders use a formula that weighs your income against your debts. They calculate your debt-to-income ratio by adding up all your monthly debt payments — car loans, student loans, credit cards, child support, any existing mortgage — and dividing by your gross monthly income (the amount before taxes). Most lenders will not lend you more than 43 percent of your gross income, though some will go to 50 percent if your credit is very strong.

Your credit score matters because it tells the lender how often you've paid bills on time in the past. Scores range from 300 to 850. Most lenders want a score of at least 620 to consider you, but better rates go to borrowers with scores above 740. Your score is based on payment history (35 percent of the score), amounts you owe (30 percent), length of credit history (15 percent), new credit inquiries (10 percent), and credit mix — meaning you have both revolving credit like credit cards and installment credit like car loans (10 percent).

The lender will also look at your employment history. They want to see that you've been at your current job for at least two years, or if you've changed jobs, that you work in the same field and your income is stable or rising. If you're self-employed, they'll ask for two years of tax returns and may ask for a profit-and-loss statement.

Finally, the lender checks your savings and assets. They want to see that you have money in the bank — usually at least 3 to 6 months of mortgage payments set aside — and that you can cover the down payment without borrowing it from someone else.

The documents you'll need to gather

Before you contact a lender, collect these items so the process moves faster:

  • Two recent pay stubs (usually from the last 30 days)
  • Two years of tax returns (your 1040 form and all schedules)
  • Two months of recent bank and investment account statements
  • A list of all debts: credit cards, car loans, student loans, personal loans, and any other monthly obligations with the account numbers and current balances
  • Proof of employment, such as an offer letter if you've been at your job less than two years
  • If you're self-employed: two years of tax returns, a profit-and-loss statement for the current year, and business bank statements
  • If you've had credit problems: a written explanation of any late payments, collections, or bankruptcy, and evidence that you've resolved the issue

The lender will ask you to sign forms authorizing them to pull your credit report and verify your employment and income directly with your employer and bank. This is normal and expected.

How the pre-approval process works, step by step

You start by contacting a bank, credit union, or mortgage company. You can do this online, by phone, or in person. The lender will ask basic questions about your income, debts, and the price range you're looking at, then send you a pre-approval process to complete.

You fill out the process — usually a form called a Uniform Residential Loan process or Form 1003 — and submit it along with the documents listed above. The lender's underwriter (the person who decides whether to lend) reviews everything and may ask follow-up questions. This stage usually takes 3 to 5 business days.

If the underwriter approves you, they issue a pre-approval letter stating the maximum loan amount, the interest rate they're offering, and any conditions you need to meet — for example, "approval is conditional on verification of employment at time of closing" or "approval is conditional on no new debt being added." This letter is valid for 60 to 90 days, depending on the lender.

Once you find a house and make an offer, you move into the formal loan process stage. The lender will order an appraisal of the house, verify your employment and income again, and pull your credit report one more time. If everything checks out and the house appraises for at least the purchase price, you move toward closing. If the house appraises for less, the lender may reduce the loan amount or you may need to renegotiate the price.

Why your pre-approval can change or fall through

Pre-approval is conditional, which means several things can cause it to disappear between the time you get the letter and the time you close on a house. If you take out a new car loan, open new credit cards, or miss a payment, your debt-to-income ratio changes and you may no longer may have access to for the same loan amount. If you change jobs or lose income, the lender will notice when they re-verify your employment.

If the house you choose appraises for less than the purchase price, the lender will only lend up to the appraised value. If you agreed to pay $300,000 but the house appraises for $280,000, the lender will only give you a $280,000 loan (assuming you still may have access to). You would need to either pay the difference out of pocket or renegotiate the price with the seller.

The lender can also deny you at closing if they discover something they missed during pre-approval — for example, if you lied about your income or if a background check reveals fraud. This is rare, but it happens.

Shopping around and comparing pre-approval offers

You are not locked into the first lender who pre-approves you. It's worth getting pre-approval from at least two or three lenders so you can compare interest rates, fees, and terms. When you explore to multiple lenders within a short window — typically 14 to 45 days, depending on the credit scoring model — the multiple credit inquiries count as a single inquiry for credit score purposes, so shopping around does not damage your score.

When you compare offers, look at the interest rate, the annual percentage rate (APR), which includes fees, the loan term (15 years, 30 years, etc.), and the estimated closing costs. A lower interest rate is not always the best deal if the fees are much higher. Use a mortgage calculator or ask each lender for a Loan Estimate form, which shows all costs side by side.

You can also negotiate with lenders. If one offers a lower rate, you can ask another lender to match it. Some lenders will waive certain fees to win your business.

What happens after you're pre-approved

With a pre-approval letter, you can start looking at houses with a real estate agent. The agent will know you're a serious buyer and can help you make competitive offers. When you find a house and make an offer, include a copy of your pre-approval letter so the seller knows the financing is likely to go through.

Once your offer is accepted, you'll move into the formal loan process. You'll sign the official loan process, the lender will order the appraisal, and the underwriter will review everything one more time. You'll also work with a title company or attorney to handle the closing paperwork. The whole process from offer to closing usually takes 30 to 45 days.

During this time, do not make any major financial changes. Do not take out new loans, open new credit cards, make large purchases, or change jobs. Do not move money between accounts in ways that are hard to explain. The lender is watching, and anything unusual can trigger questions that slow down closing or, in rare cases, cause the lender to back out.

Frequently Asked Questions

Does getting pre-approved hurt my credit score?

Yes, but only slightly and temporarily. The lender pulls your credit report, which is a hard inquiry and lowers your score by a few points. The impact fades within a few months. If you shop around with multiple lenders within 14 to 45 days, the inquiries typically count as one, so the damage is minimal.

What's the difference between pre-approval and pre-qualification?

Pre-qualification is an estimate based on information you provide — no verification. Pre-approval is based on documents the lender has actually reviewed. Pre-approval carries much more weight with sellers and real estate agents because the lender has already checked your finances.

Can I get pre-approved if I have bad credit?

It depends on how bad. Most lenders require a credit score of at least 620, though some go lower. If your score is below 620, you may need to work on improving it first by paying down debt and making on-time payments for several months. Some lenders specialize in borrowers with lower scores but charge higher interest rates.

What if my pre-approval expires before I find a house?

You can ask the lender for a new pre-approval letter. If your financial situation hasn't changed, this is usually quick. If it has changed — your income went down, you took on new debt — the lender will re-evaluate and may offer a lower amount or a higher interest rate.

Can I lose my pre-approval after I make an offer?

Yes. If you take out a new loan, miss a payment, or your employment changes, the lender may reduce your pre-approval amount or withdraw it entirely. This is why lenders tell you not to make any major financial changes between pre-approval and closing. If something does change, tell your lender when ready rather than waiting for them to find out.
