Understanding a Credit Score
Check the actual numerical credit score. If you are looking at a score above 750, you can rate that person as an excellent credit risk. If the score is under 650, the person is a poor credit risk. 720 is an average score.
Go over the potential problems section of the credit report. Any outstanding or delinquent accounts will be listed here, as well as past issues like foreclosures and bankruptcies.
Note the number of accounts in good standing. If this individual keeps all of their accounts paid and up to date, you can assume that they will do the same with your account.
Look through the history of account balances if it is provided. This list will give you a general idea of how this person has kept up with their payments in the past and offer a wider view of their credit history than just their list of accounts in good standing.
Count how many recent inquiries have been made on this person's credit report. A high number may mean that they are trying to open up new lines of credit and may have been turned down by some lenders.
Consider the overall picture before making any decisions about this person. You may need to ask the person in question for further information to understand the whole picture of their credit history.
