I have two teenage boys and I am ready to help them to start building their credit .I am really looking forward to giving them a better start than I gave myself and I am not looking forward to having to cosign for any accounts. Does anyone have any suggestion towards the best way to start building credit when starting out with a clean slate . I am trying to keep them with minimum debt ,while still achieving to have an excellent credit score by age 21. Suggestions on what type of accounts to apply for with no credit history would be great. My boys are 17 and 15.
