Having good credit is extremely important in financing your property, car or any purchase involving financing.
If you do not have good credit, you will not qualify for a loan or pay high interest on financing.
Here in the United States there are several companies that monitor our credit. The most important are Equifax, TransUnion and Experian.
Based on the report of these companies, the lender / banks stipulate the interest on your loan, the period in which the debt must be paid and the amount of credit you are eligible to receive.
As you can see your FICO as it is called is very important in financial transactions.
