Pay your bills promptly

One of the best things you can do to your financial health is: Paying your bills promptly and without any delays. This might include your house rent, home/auto mortgage, cable, internet, phone, water, electricity billsetc.,

In some apartments, they might charge a fine or some severe issues, if you don't pay your rent at the right time. I know my friend who had to pay the rent with a fine, since he was paying the rent on 6th of a month, instead of on or before 5th of the month.

Credit bureaus check and rate your credit score based on your time of payment. If you are delayed in payments by 30 days or 60 days, you will be counted for that and accordingly your credit score may go down. So, remember that this is considered as one of the main parameters in building up your credit score.
