Before you start browsing listings or attending open houses, there's one step that will save you time, heartache, and negotiating power: getting pre-approved for a mortgage. A pre-approval letter tells you exactly how much you can borrow, gives you a realistic budget for your home search, and signals to sellers that you're a serious, qualified buyer. In competitive markets, offers without pre-approval often don't even get considered.
Pre-approval is different from pre-qualification, and the distinction matters. Pre-qualification is a quick estimate based on information you provide verbally—your income, debts, assets. The lender does minimal verification, and the resulting letter carries little weight. Pre-approval involves actual documentation: the lender verifies your income through pay stubs and tax returns, pulls your credit report, confirms your assets with bank statements, and reviews your employment history. The result is a conditional commitment to lend you a specific amount—far more meaningful to sellers.
Why Pre-Approval Matters
The most obvious benefit is knowing your budget. Without pre-approval, you might spend weeks looking at homes you can't actually afford—or worse, miss out on homes you could have purchased because you didn't realize how much buying power you had. Pre-approval eliminates the guesswork. You'll know your maximum loan amount, your likely interest rate, and approximately what your monthly payment will be.

Pre-approval also strengthens your negotiating position. When you make an offer, including a pre-approval letter tells the seller that a lender has already vetted your finances. They know your offer is backed by real numbers, not wishful thinking. In a multiple-offer situation, this can be the difference between winning and losing the home.
Finally, pre-approval speeds up the closing process. Much of the documentation work is already done, so your lender can move faster once your offer is accepted. A quicker closing timeline is often attractive to sellers.
Gathering Your Documentation
The pre-approval process requires documentation—and the more organized you are upfront, the faster things will move. Start collecting these items before you even contact a lender.
For income verification, you'll need your last 30 days of pay stubs and W-2 forms from the past two years. If your income varies (commissions, bonuses, overtime), expect lenders to average it over 24 months. Self-employed borrowers face more documentation requirements: two years of personal and business tax returns, profit-and-loss statements, and potentially 1099 forms. Lenders want to see stable, consistent income that's likely to continue.
To document your assets, gather bank statements from all accounts covering the last two to three months. Lenders will scrutinize these for your down payment funds and reserves. They'll also want to see statements from investment and retirement accounts. If you're receiving gift money for your down payment, you'll need a signed gift letter stating the funds don't need to be repaid.
You'll also provide identification (driver's license or passport), your Social Security number for the credit check, and your address and employment history for the past two years. If you've changed jobs recently, be prepared to explain the circumstances—lenders prefer stability, but promotions or moves within the same industry are usually fine.
Walking Through the Process
Start by shopping multiple lenders. Interest rates and fees vary significantly between lenders, and getting quotes from at least three different sources can save you thousands over the life of your loan. Don't worry about multiple credit inquiries—credit scoring models recognize mortgage shopping behavior and treat all inquiries within a 14 to 45 day window as a single inquiry.
Once you've chosen a lender (or decided to get pre-approved by several), you'll complete a loan application. This asks for detailed information about your income, employment, assets, debts, and the type of mortgage you're seeking. Answer honestly and completely—discrepancies discovered later can delay or derail your approval.
The lender will pull your credit report, examining your payment history, outstanding debts, credit utilization, and any negative marks like collections or bankruptcies. Your credit score significantly affects both your approval odds and your interest rate. Scores above 740 typically qualify for the best rates; scores between 620 and 700 can still get approved but at higher rates; scores below 620 may need to consider FHA loans or take time to improve credit first.
A loan officer or underwriter then reviews your complete file—verifying income matches documentation, calculating your debt-to-income ratio, and confirming you meet the lender's guidelines. This typically takes one to three business days. If everything checks out, you'll receive your pre-approval letter stating the loan amount you qualify for, the loan type, and an expiration date (usually 60 to 90 days).
Maximizing Your Approval Odds
The work you do before applying can significantly impact your results. Check your credit report at least a month before applying—you can get free reports from AnnualCreditReport.com. Look for errors (wrong accounts, incorrect balances, accounts that aren't yours) and dispute any inaccuracies. Even small errors can affect your score.
Pay down existing debt if you can. Your debt-to-income ratio—the percentage of your gross monthly income that goes to debt payments—is a critical factor. Most lenders want this under 43%, and lower is better. Paying off a credit card or car loan before applying can meaningfully improve your ratio and potentially increase your approval amount.
Avoid new credit in the months before applying. Every new account lowers your average account age and can ding your score. Hard inquiries (except for mortgage shopping) also have a small negative impact. Wait until after closing to open that new credit card or finance furniture.
Keep your job stable. Lenders want to see at least two years of employment history, ideally in the same field. Changing jobs right before or during the mortgage process can complicate approval—especially if it involves a pay cut, a shift from salary to commission, or a completely new industry. If you're considering a job change, try to wait until after closing.
Finally, don't move large sums of money around without documentation. Lenders will ask about any large deposits that appear in your bank statements. If your parents are helping with the down payment, have them transfer the money early enough that it appears on two months of statements, or be prepared to document the gift thoroughly.
Pre-approval letters typically expire after 60-90 days. If your home search takes longer, you may need to update your documentation and get a new letter. Keep your lender informed of any changes to your financial situation—they'd rather know early than discover a problem at closing.

Frequently Asked Questions
Once you submit all required documents, pre-approval typically takes 1-3 business days. Some lenders offer same-day pre-approval if you apply early and have all documents ready.
Yes, pre-approval requires a hard credit inquiry which may temporarily lower your score by a few points. However, multiple mortgage inquiries within 14-45 days are typically counted as one inquiry.
Most pre-approval letters are valid for 60-90 days. After that, you'll need to update your documentation and may need a new credit check.
Yes, pre-approval is conditional. Final approval depends on the property appraisal, title search, and no significant changes to your financial situation (job loss, new debt, etc.).
