As reported by CNBC earlier this week, consumers took to Twitter to express their frustration over their credit scores on Credit Karma, the personal finance company owned by Intuit. The issue for most wasn’t that the credit scores they were finding on the Credit Karma website were low—rather they were too high. Wondering which credit score matters when buying a house?

There are multiple reasons why your credit score differs between what a personal finance website tells you and what your credit card company or a prospective lender find.

This is mainly because of two reasons: For one, lenders may pull your credit from different credit bureaus, whether it is Experian, Equifax or TransUnion. Your score can then differ based on what bureau your credit report is pulled from since they don’t all receive the same information about your credit accounts. Secondly, different credit score models (and versions) exist across the board.

Lesson learned from this week’s credit drama? The FICO® Score 8 is widely-used and can help you gauge which credit cards you qualify for. But there are also industry-specific FICO Scores to use when you are planning a certain purchase. For example, FICO® Auto Scores are ideal if you want to finance a car with an auto loan, while it’s good to check FICO® Scores 2, 5 and 4 if you plan to buy a house.
