I use a "Debt Dash" approach to paying off debt. I recommend people focus on paying off the debt with the lowest balance first. So if the primary has less debt you would focus on that.
I just don't like people taking debt into retirement.
When you give people who are being financially responsible money, you are enabling them to continue a bad habit. So you are actually helping by saying, "Love you but no."
I love teaching people how to handle their money and I've built a brand on that skill.
The sad thing is many people learn how to manage money after they've made a lot of financial mistakes, some that take decades to fix.
I'm not a fan of debt consolidation. In my experience, many people "clear" credit cards and other debt to get the one payment and never change what they need to change to prevent getting into debt again.
Kids can and are a blessing. But plenty of people without kids live and die just as happy.
