Potential creditors (and the credit score) weigh the negatives in comparison to the positives...
Meaning, if you had a lot of "good accounts" then 2 small collections wouldn't mean very much.
However, since those 2 small collections are the
only thing on your credit report, it doesn't look very good to a potential lender. They might possibly look at your credit and say "he doesn't have very much credit, and what he does have he didn't pay."
You should do your best to take care of those; try negotiating for their removal as part of your payment arrangement. Try to open a couple credit cards to establish some good history. Don't necessarily max them out or keep balances on them, but pay them off every month. Over time, it will help build some credit for you.
