Data asymmetry across bureaus means the same scoring model can produce different results at each bureau.

Request reason codes from recent applications

Reason codes reveal whether this dimension is currently suppressing your score and by how much relative to other factors.

Evaluate trended data implications

If your lender uses FICO 10T or VantageScore 4.0, the 24-month trajectory of relevant data points affects the assessment.

Preguntas frecuentes

Preguntas comunes

How does classic fico versions for mortgage lending differ between FICO and VantageScore?

FICO and VantageScore use different algorithmic architectures (logistic regression vs. machine learning), different minimum file requirements, different collection treatment, and different factor weight structures. These differences produce systematic score variance that is predictable based on specific file characteristics.

Which scoring model version should I focus on?

Focus on the version your target lender uses for underwriting. For mortgages, this is currently FICO 2/4/5 with a planned transition to FICO 10T. For credit cards and auto loans, FICO 8 is most common. Free monitoring services typically show VantageScore, which may differ materially from the lender's score.

How quickly do changes in this area affect my score?

Changes are reflected after the relevant creditor reports updated data to the bureau, typically on a monthly cycle with 2-4 week latency. Utilization changes take effect within one reporting cycle. Derogatory events have immediate impact that decays over time. Account age changes are gradual.

Can I see which specific variables are affecting my score?

FICO reason codes identify the top 4-5 factors suppressing your score. These codes provide the most actionable information about which scoring dimensions have the most room for improvement in your specific file.
