Boost Your Credit Score Before Buying a Home
Your credit score is the single most influential factor in determining your mortgage interest rate, and even a modest improvement can save you tens of thousands of dollars over the life of your loan. If you’re planning to buy a home in the coming months, improving your credit score before applying for a mortgage should be a top priority.
This guide walks you through actionable strategies to improve your credit score and position yourself for the best possible mortgage terms when you’re ready to buy.
Why Your Credit Score Matters for Mortgage Approval
Lenders use your credit score as a quick snapshot of your financial reliability. A higher score signals lower risk, which translates directly into better loan terms. Here’s what the numbers mean in practical terms:
Borrowers with scores above 760 typically qualify for the lowest available rates. Those in the 700-759 range see slightly higher rates but still access excellent terms. Scores between 620 and 699 qualify for conventional loans but at higher rates, while scores below 620 may limit options to FHA loans or require alternative financing approaches.
The difference between a 680 and a 760 credit score on a $350,000 mortgage could mean paying an extra $200 or more per month—that’s over $72,000 in additional interest over 30 years. Understanding how mortgages work is the first step; check out our complete mortgage guide for the full picture.
Check Your Credit Reports First
Before you can improve your score, you need to know exactly where you stand. Request your free credit reports from all three major bureaus—Equifax, Experian, and TransUnion—through AnnualCreditReport.com. Review each report carefully, as errors are more common than you might expect. Studies have found that roughly one in five consumers has an error on at least one credit report.
Look for inaccurate account information, incorrect payment histories, accounts that don’t belong to you, outdated negative information that should have aged off, and incorrect credit limits or balances. If you find errors, dispute them with the relevant bureau immediately. Correcting inaccuracies can produce quick, meaningful score improvements.
Six Proven Strategies to Raise Your Credit Score
1. Pay Down Credit Card Balances
Credit utilization—the percentage of available credit you’re using—accounts for roughly 30% of your credit score. Keeping your utilization below 30% is the standard advice, but for the best scores, aim for under 10%. If you have a credit card with a $10,000 limit, try to keep the balance below $1,000.
Focus on paying down cards with the highest utilization rates first. Even if the balances are small, a card that’s near its limit hurts your score disproportionately. If possible, make payments before the statement closing date so a lower balance is reported to the credit bureaus.
2. Make Every Payment on Time
Payment history is the single largest factor in your credit score, accounting for about 35%. Even one late payment can cause a significant score drop, and the impact is worse the later the payment. Set up autopay for at least the minimum payment on every account to ensure you never miss a due date.
If you have past late payments, know that their impact diminishes over time. A late payment from three years ago affects your score much less than one from three months ago. Continue making on-time payments consistently, and the negative impact will gradually fade.
3. Don’t Close Old Credit Accounts
The length of your credit history matters. Closing an old credit card reduces your average account age and decreases your total available credit, both of which can lower your score. Even if you no longer use a card, consider keeping it open with occasional small purchases to maintain the account’s positive history.
4. Become an Authorized User
If a family member or trusted friend has an old credit card with a strong payment history and low utilization, ask to be added as an authorized user. Their positive account history gets added to your credit report, potentially boosting your score. You don’t even need to use the card—simply being listed as an authorized user is enough.
5. Limit New Credit Applications
Each time you apply for credit, a hard inquiry appears on your report, which can temporarily lower your score by a few points. In the months leading up to your mortgage application, avoid applying for new credit cards, auto loans, or other financing. Multiple inquiries in a short period can signal financial distress to lenders.
Note that when you’re rate shopping for a mortgage specifically, multiple inquiries within a 14-45 day window (depending on the scoring model) are typically counted as a single inquiry, so comparing mortgage offers won’t significantly impact your score.
6. Diversify Your Credit Mix
Credit scoring models favor a diverse mix of account types, including credit cards (revolving credit), installment loans (auto loans, personal loans), and mortgage accounts. If your credit profile is limited to just credit cards, a small installment loan—paid on time—can help round out your profile. However, don’t take on unnecessary debt just to diversify; this strategy is most effective when combined with the other approaches listed here.
Timeline: How Long Does Credit Improvement Take?
Credit score improvement isn’t instant, but meaningful gains are achievable in a relatively short time. Correcting errors on your credit report can boost your score within 30 to 60 days once the dispute is resolved. Paying down high credit card balances typically shows results within one to two billing cycles. Building a consistent payment history takes longer—three to six months of on-time payments can show measurable improvement.
Ideally, start working on your credit at least six months before you plan to apply for a mortgage. This gives you time to address issues, build positive history, and maximize your score improvement.

What to Avoid While Improving Your Credit
Some well-intentioned actions can actually hurt your credit score during the improvement process. Avoid closing multiple accounts at once, which reduces available credit and shortens credit history. Don’t max out a card and then pay it off repeatedly—the high balance may be reported before the payment. Avoid co-signing loans for others, as their missed payments will affect your score. And resist the temptation to use credit repair companies that promise unrealistic results; many of the strategies they use, you can do yourself for free.
