Why does Credit Karma say I have a 640 credit score but you say my credit score is actually a 540?

This is one of the most common questions I hear from homebuyers.

The short answer is that Credit Karma and mortgage lenders are often looking at completely different scoring models.

Credit Karma primarily displays a VantageScore, while mortgage lenders use FICO scores specifically designed for mortgage lending. Even though both scores are based on information from your credit report, they calculate risk differently.

Think of it like two appraisers looking at the same house. They are reviewing the same property, but they may arrive at different values because they’re using different methods.

Mortgage FICO scores tend to place more weight on factors such as:

  • Late payments
  • Collection accounts
  • Credit card utilization
  • Length of credit history
  • Certain derogatory credit events

As a result, it’s not unusual for a mortgage FICO score to be significantly different from a Credit Karma score. Sometimes the difference is only a few points. Other times it can be 50, 80, or even 100 points.

Credit Karma is still a useful tool for monitoring changes in your credit profile, tracking accounts, and watching for potential issues. However, it should not be considered an accurate predictor of the score a mortgage lender will use to qualify you for a home loan.

The reality is that no one knows exactly where your mortgage scores fall until a lender pulls the credit report used for mortgage underwriting. That’s why I focus less on what Credit Karma says and more on what the actual mortgage credit report shows.
