Here's a radical idea: don't have any student debt!
Don't buy into the idea that your child has to go into debt to go to college. Just because most people think this way, doesn't mean it's the right way to think. In fact, if most people think a certain way about finances, investing, money management, etc., then it might not be the right way to look at those subjects.
Articles like this one can be helpful, no doubt, but they can also reinforce mass thinking.
By starting to save early for your child's college, your child working while going to college, and your child going to a community college for the first two years, you can help guide your child through college with little or no debt. Wouldn't it be great to help your child start off their career with no debt?!
It can be done. Believing it can be done helps you figure out how it can be done in your personal circumstances.
Another good approach to solving this challenge is to talk to someone who has helped his child go to college without accumulating debt. Learn from those who have done it.
