Step 1: Credit Profile Analysis
The process begins when the mortgage lender pulls the borrower’s tri-merge credit report and identifies that the borrower’s score is below a desired threshold. The loan officer uses credit score simulation tools (sometimes called “what-if” analysis) to model how specific account changes would affect the borrower’s FICO score. For example, the simulation might show that paying a credit card balance from $4,800 down to $500 would increase the borrower’s middle score by 25 points. If the simulation indicates that a targeted account change would push the score above a meaningful threshold, the loan officer recommends the rescore strategy to the borrower.
Step 2: Borrower Takes the Corrective Action
The borrower must complete the actual account change before the rescore can be initiated. This means paying down the credit card balance, settling or paying the collection account, or obtaining the error correction from the creditor or bureau. The borrower must then obtain written documentation confirming the change. For balance paydowns, this is typically a letter from the creditor or an updated statement showing the new balance and the date the payment was applied. For collections, this is a letter from the collection agency confirming the account status. The documentation must include the creditor’s name, the account number, the updated balance or status, and the effective date of the change.
Step 3: Lender Submits the Rescore Request
The lender’s credit reporting vendor submits the documentation directly to the credit bureau or bureaus where the account is reported. The vendor requests an expedited update to the borrower’s credit file based on the supporting documentation. The bureau verifies the documentation, updates the account information in the borrower’s file, and generates a new credit score reflecting the change. This process bypasses the standard monthly reporting cycle in which creditors batch-report account data to the bureaus.
Step 4: Updated Credit Report and Score
Within three to five business days, the credit reporting vendor receives the updated credit report and score from each bureau. The lender reviews the new scores to confirm that the expected improvement materialized. If the scores now meet the required threshold, the lender can proceed with rate locking, underwriting submission, or other time-sensitive steps in the loan process. If the improvement is less than expected, the loan officer may recommend additional corrective actions and a subsequent rescore, though each additional rescore incurs additional costs.
Step 5: Integration with the Loan File
The rescored credit report replaces the original credit report in the loan file. All underwriting decisions, pricing calculations, and loan-level price adjustments are based on the updated scores. The rescore documentation, including the borrower’s proof of account changes and the vendor’s rescore confirmation, is retained in the loan file as part of the credit documentation. If the loan is later audited, the rescore must be fully documented with supporting evidence for each account that was updated.
