Getting Preapproved for a Mortgage: What Happens and What You Need

What preapproval means and why lenders do it

Preapproval is a lender's preliminary decision that you can borrow a specific amount of money, based on information you provide about your income, debts, and credit. It is not a may provide — the lender will verify everything later — but it tells you and a seller roughly what price range you can afford before you start house hunting.

Lenders preapprove you because it protects them. They check your credit report, ask about your job and income, and look at your existing debts. If something changes between preapproval and closing — you lose your job, rack up credit card debt, or switch employers — they can back out. Preapproval also protects you: it forces the lender to tell you upfront what they will and will not lend, so you do not waste time looking at houses you cannot actually buy.

Preapproval is different from prequalification, which is just a rough estimate based on what you tell a lender over the phone. Preapproval requires documentation and a credit check. It is also different from final approval, which comes after the lender has inspected the specific house you want to buy and confirmed its value.

Key Takeaways

• Preapproval requires you to submit pay stubs, tax returns, bank statements, and permission for a credit check, and it typically takes three to five business days.
• The lender will tell you a maximum loan amount, but that number does not mean you should borrow it — your own budget may be lower.
• Preapproval is valid for 60 to 90 days in most cases, so you will need to reapply if you wait longer to make an offer.
• A preapproval letter shows sellers you are a serious buyer, but it does not obligate you to buy or lock in your interest rate.
• Multiple preapproval requests within two weeks count as one inquiry on your credit report, so you can shop around without penalty.

Documents you will need to gather

Lenders ask for the same documents regardless of which bank or mortgage company you use. Bring or upload two months of recent pay stubs, two years of tax returns (both your personal return and any business returns if you are self-employed), and two months of bank statements showing your savings and checking accounts. If you receive income from sources other than a job — rental income, alimony, Social Security, or investment dividends — bring documentation for that too.

You will also need to list your debts: credit cards, car loans, student loans, and any other money you owe. The lender will pull your credit report themselves, but having your own list ready speeds things up and catches errors before the lender sees them. Bring your driver's license or passport for identification, and be ready to explain any large deposits into your bank account or any gaps in employment in the past two years.

If you are self-employed or have been in your current job for less than two years, bring additional documentation: profit-and-loss statements, business tax returns, or an offer letter from your new employer. If you have experienced a major life event — divorce, bankruptcy, or foreclosure — in the past seven years, the lender will ask about it and may request court documents or settlement papers.

How the preapproval process works, step by step

Start by contacting a lender directly — a bank, credit union, or mortgage company. You can call, visit in person, or apply online. The lender will ask basic questions about your income, debts, and the type of home you want to buy, then tell you what documents to submit. Most lenders accept documents by email, secure upload portal, or in person.

Once you submit your documents, the lender's underwriter reviews them. They verify your income by contacting your employer or reviewing your tax returns, check your credit report, and calculate your debt-to-income ratio — the percentage of your monthly income that goes toward debt payments. This step usually takes two to five business days. If the underwriter needs clarification on anything, they will contact you by phone or email.

If everything checks out, the lender issues a preapproval letter stating the maximum loan amount, the interest rate they are offering (which is not locked in yet), and any conditions — for example, that you must maintain your current job or that the appraisal must come in at a certain value. You can then use this letter when you make an offer on a house.

What your preapproval letter does and does not may provide

A preapproval letter tells a seller that a lender has reviewed your finances and believes you can borrow up to a certain amount. It makes your offer more attractive than an offer from someone with no preapproval, because the seller knows you are less likely to back out due to financing problems. However, preapproval does not mean the lender has committed to lending you that money.

The lender can still deny you at final approval if your circumstances change — if you lose your job, miss payments on other debts, or if the house appraises for less than the purchase price. The interest rate on your preapproval letter is not locked in unless you pay a fee to lock it, and even then the lock is usually good for only 30 to 60 days. If rates drop, you benefit; if rates rise, you are protected by the lock.

The preapproval amount is also not a recommendation for how much to borrow. Lenders calculate the maximum you can afford based on debt-to-income ratios, but that does not account for your own comfort level, your job security, or your other financial goals. Many financial advisors suggest borrowing no more than 28 percent of your gross monthly income for housing costs, which may be less than what the lender says you can afford.

How preapproval affects your credit score

A preapproval requires a hard inquiry on your credit report, which temporarily lowers your credit score by a few points — usually between 5 and 10 points. The impact is small and fades within a few months. The good news: if you apply for preapproval with multiple lenders within a two-week window, the credit bureaus count all those inquiries as a single inquiry, so you can shop around without additional damage to your score.

After the two-week window closes, each new preapproval request counts as a separate inquiry. If you are still house hunting after two weeks and want to compare rates from another lender, you can do so, but know that it will show as another inquiry. Do not apply for new credit cards, car loans, or other credit during the preapproval and home-buying process, as each inquiry adds up and can lower your score enough to affect your interest rate.

How long preapproval lasts and when you need to reapply

Most preapproval letters are valid for 60 to 90 days. Some lenders offer 120-day preapprovals, but 60 to 90 days is standard. The clock starts the day the lender issues the letter, not the day you receive it. If you have not made an offer within that window, you will need to reapply — the lender will pull a new credit report and ask for updated financial documents.

If you do make an offer and the lender moves to final approval, your preapproval letter is no longer the active document — the final approval takes over. Final approval typically comes after the house inspection and appraisal, which can take another two to four weeks. If there is a long delay between preapproval and final approval, the lender may ask for updated pay stubs or bank statements to confirm nothing has changed.

Preapproval versus prequalification versus final approval

These three terms describe different stages, and mixing them up can lead to disappointment. Prequalification is the fastest and least rigorous: you tell a lender roughly what you earn and owe, and they give you a ballpark figure for how much you might borrow. No documentation is required, no credit check happens, and it carries no weight with a seller. It is useful only as a starting point to understand your own budget.

Preapproval requires documentation and a credit check. A lender verifies your income and debts and issues a letter saying you can borrow up to a specific amount. Sellers take preapproval seriously because it shows you have been vetted. However, preapproval is not final — the lender can still back out if circumstances change.

Final approval comes after you have made an offer on a specific house. The lender orders an appraisal, inspects the property, and confirms that the house is worth what you are paying for it. Final approval is the closest thing to a may provide, though even then the lender can make approval conditional on the appraisal coming in at a certain value or on you maintaining your job through closing.

Frequently Asked Questions

Do I need preapproval before I start looking at houses?

It is not required, but it is strongly recommended. Preapproval tells you what you can afford and shows sellers you are serious. Without it, you may fall in love with a house you cannot actually buy, or waste time looking at homes outside your budget. Most real estate agents will not show you houses without preapproval.

Can I get preapproved with bad credit?

Yes, but you may face higher interest rates or be required to make a larger down payment. Credit scores below 620 are difficult to work with at traditional banks, but credit unions and some mortgage companies specialize in borrowers with lower scores. Expect to pay more for the loan, and be prepared to explain any negative marks on your credit report.

What if my preapproval expires before I find a house?

You will need to reapply. The lender will pull a new credit report and ask for updated pay stubs and bank statements. The process is faster the second time because the lender already has your file, but it still takes a few business days. If your financial situation has not changed, reapproval is usually straightforward.

Does preapproval lock in my interest rate?

Not automatically. Your preapproval letter shows an interest rate, but that rate is not locked unless you pay a fee to lock it — usually between $300 and $500. A rate lock is typically good for 30 to 60 days. If you do not lock the rate and rates rise before closing, your rate rises too. If rates fall, you benefit.

Can I be denied after preapproval?

Yes. Preapproval is not a final commitment. If you lose your job, miss payments on other debts, or if the house appraises for significantly less than the purchase price, the lender can deny final approval. This is rare, but it happens. Avoid major financial changes between preapproval and closing.
