Length of credit history takes into account how long your credit accounts have been established, including the age of your oldest account, the average age of all your open accounts and the age of specific types of accounts.
Your credit score benefits from having open accounts with an average age of at least 24 months.
The older the accounts the better, this all comes back to stability.
Someone with 3 credit cards they have had for fifteen years and a mortgage that’s over ten years old is going to look more stable than someone who just started establishing credit 3 months ago.
• Have an average age of open accounts of 11 or more years
• Age of oldest account is 25 years, on average
