My husband and I recently had our first child. We are considering opening a 529 plan for him, but between the two of us, we still have about $15,000 in college loan debt. Our student loans are locked in at a low interest rate (around 3 percent). On the one hand, we know that money invested in a 529 plan now will earn more over time than money invested later. On the other hand, it seems kind of odd to start saving for his college when we haven't finished paying for our own. Does it make more sense financially to open a 529 plan for him now, or to put the money we would have put into it toward paying off our own student loans first? Carol, Athens, GA
