Lenders may request a copy of credit reports when you apply to for a loan. This is called a "hard inquiry" and it will affect your credit score. These inquiries will not be included in your credit score for one year. They will also disappear from your credit history after two years.
Average age of accounts
The average age of your accounts should be considered when looking at credit history. Longer credit histories will improve your credit score. A shorter history will lower it. Your credit history can be affected by many factors, such as your age and demographics. Your credit score will increase if you keep your accounts current and open.
If you are applying for a loan and/or a credit card, a long credit record will be of benefit. The average age of your credit history will decrease if you open new credit accounts. You should be cautious about opening new accounts unless they will help you achieve your goals.
