If you need to borrow in the next 3-6 months, these are the highest-impact moves ranked by speed:
1. Dispute Errors on Your Credit Report (Impact: days to weeks)
About 1 in 5 consumers has an error on at least one credit report, according to FTC findings. Pull your reports from all three bureaus at AnnualCreditReport.com. Look for accounts you don't recognize, late payments that were actually on time, wrong balances, and duplicate accounts. File disputes directly with each bureau — under the FCRA, they must investigate within 30 days. Correcting a single error can boost your score by 25-100 points depending on the severity.
2. Pay Down Credit Card Balances (Impact: 1-2 billing cycles)
Your credit utilization ratio (how much of your available credit you're using) accounts for roughly 30% of your FICO score. Dropping your utilization can add significant points. The ideal target is below 30%, but lower is even better. Pay down the card with the highest utilization first.
3. Become an Authorized User (Impact: 1-2 months)
If someone you trust (family member, partner) has a credit card with a long history and low utilization, ask them to add you as an authorized user. Their positive account history gets added to your credit report. You don't even need to use the card.
4. Don't Open New Accounts Before Applying (Impact: immediate)
Every new credit application triggers a hard inquiry, which can drop your score by a few points. If you're about to apply for a mortgage or major loan, stop applying for anything else 3-6 months beforehand.
5. Ask for a Credit Limit Increase (Impact: 1 billing cycle)
If you have existing credit cards in good standing, call the issuer and request a higher limit. If they grant it without a hard pull, your utilization ratio drops instantly, which raises your score. Ask specifically: "Can you do a soft pull for this request?" If they say it requires a hard pull, weigh whether the utilization improvement is worth the inquiry.
