How to Get Pre-Approved for a Mortgage: Step by Step

Getting pre-approved for a mortgage is the point where house hunting stops being a weekend hobby and becomes a real plan. Before a pre-approval, you are guessing at your price range. After it, you have a number in writing that sellers, listing agents and your own agent can rely on. In a market where good homes still draw more than one offer, that letter is often what decides whether your offer is taken seriously or set aside.

The process itself is not complicated. You check your credit, work out your debt-to-income ratio, gather proof of your income and assets, choose where to apply, and receive a pre-approval letter that states how much you can likely borrow. This guide walks through each of those steps in order, explains what gets checked along the way, and shows you how to keep your letter useful until you close.

What a Mortgage Pre-Approval Actually Is

A mortgage pre-approval is a written statement that, based on the information checked so far, you can likely borrow up to a certain amount for a home purchase. It carries more weight than a prequalification because some or all of your financial details have been confirmed rather than simply stated. Sellers and their agents know the difference, which is why most will ask for a pre-approval letter before they consider an offer.

A pre-approval is not a final loan approval. After you go under contract on a house, the lender still has to order an appraisal, review your full file in underwriting, check your credit and confirm that nothing important has changed since your letter was issued. Think of the letter as strong evidence that you are a qualified, serious buyer rather than a promise that a loan will close.

If you are still unsure where prequalification ends and pre-approval begins, our guide to the difference between prequalified and preapproved covers it in more detail.

Step 1: Check Your Credit Before a Lender Does

Start by pulling your credit reports. You can get free reports from Equifax, Experian and TransUnion at AnnualCreditReport.com, which is the site the Consumer Financial Protection Bureau directs consumers to. Reviewing all three matters, because lenders may see slightly different information depending on which bureau they use.

Read each report line by line. Look for accounts you do not recognize, late payments that were actually made on time, balances you have already paid off and old addresses that do not belong to you. If you find a genuine error, dispute it with the bureau that reports it. Disputes can take 30 days or longer to resolve, so this step belongs at the very beginning of the process, not in the middle of an application.

What Score Do You Need?

Minimum scores depend on the loan program. Conventional loans generally start around 620 under Fannie Mae's guidelines. FHA loans can accept lower scores, especially when the buyer puts more money down. VA and USDA loans set their own standards, and individual lenders can add requirements on top of the program minimums. You can see how each program compares in our guide to the credit score lenders look for.

A higher score does more than help you qualify. It usually affects how a loan is priced, and pricing often moves in steps of around 20 points. That means a modest improvement before you apply, such as paying a credit card balance down below 30 percent of its limit, can make a real difference to the cost of your loan over time.

Step 2: Work Out Your Debt-to-Income Ratio

Your debt-to-income ratio, usually called DTI, compares your monthly debt payments with your gross monthly income. Lenders watch it closely because it shows how much room your budget has left for a mortgage payment. Two buyers with the same income can qualify for very different amounts if one carries a large car payment and the other does not.

To calculate it, add up your minimum monthly payments on car loans, student loans, credit cards, personal loans and any child support or alimony you pay. Do not include utilities, phone bills, insurance or groceries. Divide the total by your monthly income before tax and multiply by 100.

Many lenders like to see a total DTI at or below 36 percent. Fannie Mae's guidelines allow higher ratios in some cases, particularly when the borrower has strong credit and savings. If your ratio is high, paying off a small loan completely often helps more than spreading the same money across several balances, because it removes an entire payment from the calculation. Our guide on how lenders calculate debt to income has more worked examples.

Step 3: Gather Proof of Income and Assets

Most traditional pre-approvals ask you to prove what you earn and what you have saved. Having these documents ready before you apply can save days of back and forth with a loan officer.

Self employed buyers usually need more, often two full years of personal and business tax returns and sometimes a year to date profit and loss statement. Lenders may also ask about large or unusual deposits on your bank statements, so be ready to explain where any big transfer came from. If part of your down payment is a gift from family, you will typically need a signed gift letter. Keep the full document checklist open while you gather everything.

Step 4: Choose How to Get Pre-Approved

There are three main routes to a pre-approval letter. They differ mostly in how they check your credit, how they confirm your finances and how quickly you get an answer.

A Bank or Credit Union

Your own bank or credit union already holds your accounts and knows your history, which can make the conversation easier. Expect a hard credit check and a request for the documents listed above. Turnaround can range from the same day to several days, depending on how busy the loan team is.

An Online Lender

Online lenders handle the application through a website or an app. Some start with a soft credit check and confirm your numbers later in the process. Others run a hard credit check from the start. Read the details before you apply so you know which kind of check you are agreeing to.

A Verification First Option

Some services confirm your income and assets directly from your bank accounts through a secure, read only connection, then issue a pre-approval letter without a credit inquiry at that stage. Preqly works this way. It is not a lender. Loans come from partner banks and lenders, and a lender will check your credit before final approval.

Whichever route you choose, getting pre-approved for a home loan works the same way underneath. Someone reviews your numbers and puts an amount in writing. The real differences are how much of your information is verified and what the process does to your credit report.

Step 5: Apply and Get Your Pre-Approval Letter

When you apply for mortgage pre-approval, you share your income, monthly debts, savings, the price range you have in mind and the type of loan you expect to use. Be accurate. A letter built on rounded up income or savings you do not quite have will fall apart the moment underwriting cannot confirm it, and that usually happens after you have already signed a purchase contract.

Timing depends on the route. A bank that reviews documents by hand may take a few days. Online and verification based options can return a letter in minutes, and Preqly's takes about 90 seconds. There is more on what affects turnaround in our guide to how long pre-approval usually takes.

What the Letter Shows

A typical pre-approval letter lists your name, the maximum loan or purchase amount, the loan type, an expiration date and the company that issued it. Some letters also state exactly what was verified. Listing agents read that part closely, because a letter based on verified income and assets carries more weight than one based on figures the buyer typed into a form.

Ask for a Letter Matched to Each Offer

If your maximum is $400,000 but you are offering $360,000 on a particular house, some buyers ask for a letter showing the offer amount rather than the maximum. It keeps your full budget private during negotiation. Ask your issuer whether they can adjust the amount for individual offers.

Step 6: Use the Letter and Keep It Current

Most pre-approval letters are valid for 60 to 90 days. If your search runs longer, you will need an update, which usually means refreshing your income and asset information so the letter still reflects your current situation. Our guide to how long a pre-approval lasts explains what happens when a letter expires.

Between pre-approval and closing, keep your finances as steady as you can. Avoid opening new credit cards, financing a car or furniture, changing jobs or moving large sums between accounts without a paper trail. Any of these can change your DTI or your credit profile, and the lender will check again before the loan closes. To see where pre-approval sits in the bigger picture, read the mortgage process step by step.

Common Mistakes That Slow a Pre-Approval Down

Most delays come from a handful of avoidable problems. The first is applying before checking credit, which leaves no time to fix errors. The second is incomplete paperwork, such as bank statements with missing pages or a tax return without its schedules. The third is unexplained deposits, which lenders must trace before they can count the money.

The last is guessing at income. Overtime, bonuses and commission usually need a two year history before a lender will count them, so base your expectations on the income you can document today.

Prequalified or Pre-Approved?

Prequalification is a quick estimate based on what you tell a lender about your finances. Pre-approval goes further by checking some or all of that information. If you want to know how to prequalify for a mortgage, it is simple: share your income, debts and savings through a short form and you will get a rough range within minutes. It is a useful first look at your budget, but sellers give a pre-approval far more weight, so treat prequalification as a starting point rather than something to put in front of a seller.

Frequently Asked Questions

Q. How do I get pre-approved for a home loan with no credit history?

A: Some lenders accept alternative credit, such as rent, utility and phone payment records, especially for FHA loans. Expect to show around 12 months of on time payments. A verification based pre-approval can still confirm your income and assets, but a lender will need to assess your credit before final approval.

Q. How long does it take to get pre-approved for a mortgage?

A: Anywhere from a few minutes to a few days. Document reviews at a bank take the longest. Online and verification based options are faster, and Preqly issues a letter in about 90 seconds.

Q. Does getting pre-approved hurt your credit?

A: It depends on the check. A hard inquiry can lower a score by a few points for a short time, while a soft check or a verification without a credit inquiry has no effect. See how pre-approval affects your credit score.

Q. How do I get prequalified for a home loan?

A: Share your income, debts and assets with a lender, usually through a short online form, and you will get an estimated range within minutes. Prequalification is not verified, so it carries less weight with sellers than a pre-approval.

Q. Can I get pre-approved with more than one lender?

A: Yes, and comparing lenders is a good idea. FICO scoring models treat multiple mortgage inquiries within a short window, 14 to 45 days depending on the version, as a single inquiry, so do your comparing inside that window.

Q. What should I do after I get my pre-approval letter?

A: Share it with your agent, set your search range a little below the maximum, and keep your finances steady. Avoid new credit and large unexplained transfers until after closing.
