Getting preapproved for a mortgage is one of the most useful steps you can take before you start touring homes. A preapproval letter tells sellers and real estate agents that a lender has reviewed your finances and is willing to lend you a specific amount, subject to final underwriting. In competitive markets, many listing agents will not schedule showings without one. Here is how the process works, what lenders look for, and how to position yourself for a smooth approval.
Preapproval vs. Prequalification: Know the Difference
These terms are often used interchangeably, but they carry different weight. A prequalification is typically a quick, soft-pull estimate based on self-reported income and debt. It takes minutes and is useful for early budgeting, but it is not a commitment.
A mortgage preapproval is more rigorous. The lender verifies your income, assets, and credit, usually with a hard credit inquiry, and issues a conditional commitment for a specific loan amount. That letter is what sellers take seriously. Expect the preapproval to include an expiration date, commonly 60 to 90 days, after which you may need to refresh it.
Step 1: Check and Strengthen Your Credit Profile
Before you apply, pull your credit reports from AnnualCreditReport.com, the site authorized by federal law to provide free reports from the three nationwide bureaus. Review them for errors, such as accounts that are not yours or incorrect late payments, and dispute anything inaccurate with the bureau.
Most conventional loans require a minimum credit score around 620, while FHA loans backed by the Federal Housing Administration allow scores as low as 580 with a 3.5% down payment. Higher scores generally translate into lower interest rates. If you are close to a threshold, paying down revolving balances and avoiding new credit applications for a few months can help.
Step 2: Gather Your Documentation
Lenders want a verifiable picture of your finances. Having these documents ready speeds up the process considerably:
- Income: Recent pay stubs, W-2s for the past two years, and tax returns if you are self-employed or have rental income.
- Assets: Statements for checking, savings, brokerage, and retirement accounts covering the down payment and closing costs.
- Debt: Account statements for auto loans, student loans, and credit cards.
- Identity and housing: Government-issued ID, Social Security number, and rental history or landlord contact information.
- Down payment source: Documentation for any gift funds, including a signed gift letter from the donor.
Step 3: Compare Lenders and Get Preapproved
Rates and fees vary meaningfully between lenders, so shop at least three. You can get quotes from banks, credit unions, and mortgage brokers. When comparing, ask for a Loan Estimate, the standardized three-page form required by the Consumer Financial Protection Bureau, which makes it easy to compare interest rate, monthly payment, and closing costs side by side.
Multiple mortgage inquiries within a focused shopping window, generally 14 to 45 days depending on the scoring model, are typically treated as a single inquiry for credit scoring purposes. That means comparison shopping is unlikely to damage your score the way several unrelated credit applications would.
Once you choose a lender, you will complete a full application, often online. The lender runs a hard credit pull, verifies your documents, and issues the preapproval letter. Ask how long it is valid and whether it can be updated if your target price changes.
Step 4: Understand What the Preapproval Amount Really Means
A preapproval is a maximum, not a recommendation. Lenders calculate your debt-to-income ratio (DTI), which compares your total monthly debt payments to gross monthly income. Many conventional loans allow a DTI up to 43% to 50%, depending on compensating factors, but borrowing at your ceiling can leave little room for property taxes, insurance, maintenance, and savings.
Use the preapproval as a starting point, then build a realistic budget. Factor in homeowners insurance, property taxes, HOA dues, and a reserve for repairs. A home that fits comfortably within your monthly cash flow is a better long-term decision than one that maxes out your approval.
Step 5: Keep Your Finances Stable Until Closing
Preapproval is conditional. Between the letter and closing, lenders may re-verify your employment and assets. Avoid major financial changes: do not open new credit cards, finance a car, change jobs without informing your lender, or move large sums between accounts without a paper trail. Undocumented deposits can trigger questions during underwriting.
If your situation changes, tell your loan officer early. Transparency prevents surprises and keeps your closing timeline on track.
What to Remember
Mortgage preapproval is a verified, lender-issued estimate of what you can borrow, and it is a practical first move for serious buyers. Check your credit reports, gather income and asset documentation, compare at least three lenders using Loan Estimates, and treat the approved amount as a ceiling rather than a target. Keep your finances steady through closing, and refresh your letter if it expires before you find the right home. Done carefully, preapproval shortens your house hunt and makes your offer more credible to sellers.
