HELOC vs. Parental Student Loans vs. Second Mortgage?
Debt is no fun. Getting out of debt to replace it with more debt is no fun. In both cases, you are making an investment in your child's future. That's laudable, but there might be other ways to economize on the education costs. I prefer HELOC debt because I can deduct the interest (as you pointed out) and it usually allows re-borrowing if other cash-flow problems crop up. The downside of borrowing against your house is that your house could be foreclosed if you become insolvent, and you will lose your buffer if you max out the equity now. The same problem exists with a 2nd mortgage. The fact that you would still have a mortgage either way does make the option more attractive though (or less unattractive anyway).
