Key takeaways
- A preapproval is a conditional, document-verified estimate of how much a lender may lend you; it is not a final loan commitment.
- Prequalification relies mostly on self-reported data, while preapproval uses verified documents and usually a hard credit pull.
- Gather 30 days of pay stubs, two years of W-2s and tax returns, and two months of complete bank statements.
- Most preapprovals last about 60 to 90 days; mortgage inquiries within a short window count as one for FICO scoring.
- Avoid new credit, job changes, and undocumented deposits between preapproval and closing.
A mortgage preapproval is a lender's written statement that, based on a review of your credit, income, assets, and debts, you are likely to qualify for a loan up to a specific amount. In most competitive housing markets, it is the document that makes a seller and their agent take your offer seriously. This guide explains exactly what a preapproval is, how it differs from a prequalification, which documents to gather, how long a preapproval lasts, and how to protect it until closing.
What a mortgage preapproval is
During preapproval, a loan officer collects your application, pulls your credit report, and reviews documents that verify your income and assets. Many lenders run the file through an automated underwriting system, such as Fannie Mae's Desktop Underwriter or Freddie Mac's Loan Product Advisor for conventional loans, or the FHA TOTAL Scorecard for FHA loans. The result is a letter stating the loan amount, loan type, and sometimes the estimated down payment you were reviewed for.
A preapproval is conditional. It is not a final loan commitment. Final approval still depends on an acceptable appraisal, a clear title, a full underwriting review, and your financial picture staying the same between now and closing. Still, because the lender has actually verified your information, a preapproval carries much more weight than an estimate based on what you say about yourself.
Prequalification vs. preapproval
The two terms are often used loosely, and some lenders use them differently, so always ask what review was done. In general:
| Feature | Prequalification | Preapproval |
|---|---|---|
| Information used | Mostly self-reported income, debts, and assets | Verified documents plus a credit report |
| Credit check | None or a soft inquiry | Usually a hard inquiry |
| Time to complete | Minutes | Often one to several business days |
| Strength with sellers | Limited | Strong; often expected with an offer |
| Best used for | Early budgeting and comparing options | Actively shopping and making offers |
A prequalification is a good starting point when you are months away from buying. Once you are ready to tour homes and write offers, get preapproved. If you are not sure how the different inquiry types affect your score, our explainer on soft vs. hard credit checks covers the details.
Documents you will need
Having your paperwork ready is the single biggest factor in how fast a preapproval comes back. Most lenders ask for some version of the following:
Identity and basics
- Government-issued photo ID
- Social Security number (for the credit pull and income verification)
- Current address and two years of residence history
Income and employment
- Pay stubs covering the most recent 30 days
- W-2 forms for the past two years
- Federal tax returns for the past two years, especially if you are self-employed, earn commission, or have rental income
- For self-employed borrowers: a year-to-date profit-and-loss statement and possibly business tax returns
- Award letters for Social Security, pension, disability, or other benefit income
Assets
- Two months of statements for checking, savings, and investment or retirement accounts
- A signed gift letter if a family member is helping with the down payment
- Explanations for any large, unusual deposits
Debts and other items
- Statements for student loans, auto loans, and other installment debts
- Divorce decree or child support orders, if applicable
- Bankruptcy or foreclosure discharge papers, if applicable

What lenders look at
Preapproval comes down to four questions: can you repay, will you repay, do you have the cash, and does the loan fit program rules?
- Credit score and history. FICO scores range from 300 to 850. Conventional loans generally require at least 620, while FHA allows 3.5% down at 580 or higher and 10% down at 500 to 579. Higher scores typically earn better pricing.
- Debt-to-income ratio. Lenders compare your monthly debts, including the projected mortgage payment, to gross monthly income. Our guide to how much house you can afford walks through the 28/36 rule of thumb.
- Employment and income stability. A two-year history in the same line of work is the common benchmark, though gaps can often be explained.
- Assets and reserves. You need enough verified funds for the down payment and closing costs, and sometimes a reserve cushion afterward.
The preapproval process, step by step
- Check your credit first. Pull your free reports from all three bureaus at AnnualCreditReport.com and dispute any errors before a lender sees them. A corrected late payment or duplicate collection can make a real difference in pricing.
- Choose a loan type to discuss. Knowing whether you are leaning toward FHA or conventional helps the loan officer run the right scenario. Our FHA vs. conventional loan comparison can help you decide.
- Complete the application. Most lenders use the Uniform Residential Loan Application, which asks for employment, income, assets, debts, and the type of property you plan to buy.
- Authorize the credit pull and upload documents. The faster you provide complete paperwork, the faster the file moves.
- Answer follow-up questions. Expect requests to explain large deposits, employment gaps, or recent credit inquiries. Short, written explanations are usually enough.
- Review the letter. Confirm the loan amount, loan program, and expiration date are correct before you share it with your agent.
What a preapproval letter includes
A typical letter lists your name, the maximum loan amount or purchase price, the loan program, sometimes the assumed down payment, and an expiration date. Many agents prefer a letter tailored to each offer at the exact offer price, so sellers do not see your full ceiling. Ask your loan officer whether they can issue updated letters quickly, especially on weekends when offers often move fast.
Remember that the amount on the letter is the most a lender is willing to lend under its guidelines, not necessarily what fits your budget. Taxes, insurance, childcare, and savings goals are your call, not the lender's.
How long a preapproval lasts
Most preapproval letters are valid for roughly 60 to 90 days, though the exact window varies by lender. The time limit exists because the documents behind it age: credit reports, pay stubs, and bank statements all have shelf lives under lending guidelines. If your search runs longer, the lender will usually refresh the file with updated pay stubs and statements and may pull credit again.
Shopping multiple lenders is worth it, and it does not have to hurt your credit much. FICO scoring models treat multiple mortgage inquiries within a short window as a single inquiry for scoring purposes; newer models use a 45-day window and older versions use 14 days. Concentrating your rate shopping into a couple of weeks is the safest approach. Compare offers using the Loan Estimate each lender provides, and read our guide on how to compare loan offers for a side-by-side method.
How to protect your preapproval until closing
Lenders typically re-verify employment and may re-check credit shortly before closing. Changes in your finances can shrink your approval or derail it entirely. Between preapproval and closing:
- Do not open new credit cards or finance a car, furniture, or appliances.
- Avoid changing jobs, especially to a new field or to self-employment, without talking to your loan officer first.
- Keep paying every bill on time; a single late payment can drop your score.
- Do not move large sums between accounts or make big cash deposits you cannot document.
- Do not co-sign for anyone else's loan.
Getting started
A sensible order is to check your credit reports for errors, estimate your budget, gather your documents, and then request preapproval from two or three lenders within the same couple of weeks.

The bottom line
A mortgage preapproval is a conditional, document-verified estimate of how much a lender may let you borrow, and it is far stronger than a prequalification when you make an offer. Gather pay stubs, W-2s, tax returns, and bank statements before you apply, shop lenders within a tight window, and keep your finances steady until closing. Preapprovals typically last 60 to 90 days, so time yours to match your search. When you are ready to be connected with mortgage partners in the Lending Buddy network, you can Apply Now.
Frequently Asked Questions
Does getting preapproved hurt my credit score?
A preapproval usually involves a hard inquiry, which may lower your score by a few points temporarily. FICO models count multiple mortgage inquiries within a short window as one for scoring, 45 days in newer versions and 14 days in older ones. Keeping your lender comparisons within about two weeks limits the impact while still letting you shop for the best terms.
Can I be denied a mortgage after being preapproved?
Yes. A preapproval is conditional. Final approval depends on the appraisal, title review, full underwriting, and your finances staying stable. New debt, a job change, missed payments, or a low appraisal can all lead to changes or a denial. Keeping your financial situation steady until closing is the best way to protect your preapproval.
How many lenders should I get preapproved with?
Many buyers request preapproval or Loan Estimates from two to four lenders. Comparing several offers can reveal meaningful differences in rate, points, and lender fees. Submitting those applications within a short period helps limit the credit score impact, and comparing standardized Loan Estimates line by line makes the differences easy to spot.
What happens if my preapproval expires before I find a home?
Your lender can usually renew it. Expect to provide updated pay stubs and bank statements, and the lender may pull your credit again. If your income, debts, or the interest rate environment changed, the renewed preapproval amount may be different. Contact your loan officer a week or two before expiration to avoid gaps while you are making offers.
