When we talk about credit scores, there are typically two significant players, FICO and VantageScore. Each uses similar factors to determine your credit score within their system.
Many factors can impact your credit score. Some more than others, but each aspect is just a piece of the puzzle when lenders look at the risk level associated with lending you their money.
Getting your credit score is a relatively straightforward process. You can get a full credit report from each of the three credit bureaus once per year from AnnualCreditReports.com.
