Keep in mind that the information on your credit reports may not change every time you update them on Credit Karma. It usually takes about 30 days for creditors to report new information (like new balances or payment activity) to the credit bureaus, and the frequency of updates can vary by creditor.
My Credit Karma score is a 661 - My REAL Trans Union score (as per the one I bought, and the one car dealers showed me) is a 760. 99 points different. For certain Credit Karma is NOT using the actual Trans Union credit score.
