Can you explain why these items are considered negatives on my credit report?
Creditworthiness is proven over time. The longer your track record of making payments on time, the more probable you will stick to credit agreements in future (or so the reasoning goes). Conversely, someone who has only just started applying for credit could be someone whose finances were previously stable but have now started to get into difficulty. Obviously this is not necessarily the case but it is one possible inference. This inference is strengthened when same person applies for further credit in a short space of time.  Ultimately, what is considered positive is a stable credit record over a reasonable period of time, because it indicates you stick to payment schedules and don't suddenly need credit due to money problems. Credit card accounts are considered a good indicator of credit status because they imply what kind of borrower you are. Whereas many credit arrangements present a straightforward case of arrears / no arrears (e.g. think of a mobile phone account – either you pay your bill or you don't), with credit cards there is an element of flexibility in how much you borrow, and how much of that you repay. If you run up four figure monthly balances but clear them in full each month without fail, that is a good sign. If your average balance is increasing and you are paying on time but just the minimum amount, that is a potential flag. In other words, credit cards are of particular interest because they paint a more nuanced picture. Provided you use one responsibly, getting and using a credit card may improve your status with credit reference agencies.
