How Can You Raise Your Credit Score or Fix Report Errors Before Applying for a Mortgage?
The two most reliable moves are paying down credit card balances and getting real errors on your report corrected, and both can happen in the weeks before you apply. How much your score moves depends on what's pulling it down and how well you can document an error.

Payment history and credit utilization, how much of your available card credit you're using, are the two biggest parts of a FICO score. Paying card balances down so your utilization drops, and paying everything on time, are the levers you control most directly. How much that helps depends on your starting score and the rest of your credit. If you have limited cash, a credit score simulator can show which balances are worth paying first.
Can disputing an error help me qualify?
Yes, if the item is truly wrong, duplicated or fraudulent. Under the Fair Credit Reporting Act, you can dispute it with the credit bureaus and with the company that reported it. A bureau investigation usually takes up to 30 days, or up to 45 if you send more information during it. Ask for the item to be deleted, not just updated, and keep the written confirmation.
During underwriting, your lender can order a rapid rescore once the correction is documented, which can post within a few days to about a week. You can't order one yourself.
What if a debt is deferred, or my current mortgage shows past due?
A deferred debt, like a student loan on pause, generally still counts in your debt-to-income ratio unless it's shown to be wrong, discharged or forgiven. A current mortgage reporting past due is generally a hard stop for new financing until it's brought current and the report reflects it. If you think a payment was misapplied, dispute it early, because fixing it takes documentation and time.
It depends on your situation:
- The item is clearly wrong: dispute it with the bureaus and the reporting company, and keep the confirmation for your loan file.
- The item is accurate but old or a one-time problem: a letter of explanation may let underwriting move forward without removing it.
- Your student loan is deferred, not forgiven: plan on it counting in your debt-to-income ratio.
- Your current mortgage is reporting late: bring it current first.
- You're not sure which balance to pay first: model a few options before you spend the cash.
Lenders in our network commonly accept a brief letter of explanation for an older derogatory item rather than requiring it to be removed, which can save time compared with a long dispute.
