Equifax is one of the three major credit bureaus that track a potential homebuyer's credit history. When a home buyer submits a mortgage application to a bank, Equifax Credit Information Services, Inc. could be consulted to see how much of a risk is involved in lending money to the potential buyer. The credit report is compiled using many different factors, including the current balance on the homeowner's other credit accounts, the amount of time the accounts have been open, whether or not the homeowner generally pays his bills on time, and several other factors. A good credit score and report can reduce the amount of interest you have to pay to the bank on top of the principal for your home.
