credit profiles. What's important is the mix of information, which varies from person to person, and for any one person over time.
Your FICO score only looks at information in your credit report.
However, lenders look at many things when making a credit decision including your income, how long you have worked at your present job and the kind of credit you are requesting.
Your score considers both positive and negative information in your credit report.
Late payments will lower your score, but establishing or reestablishing a good track record of making payments on time will raise your score.
