Should I use my non-tax advantaged investment account to pay off debt?
If what you are paying in interest on the debt is a higher percentage than what your investments are returning, the best investment you can make is to pay off the debt. If you're lucky enough to be paying historically low rates (as I am on my mortgage) and getting good returns on the investments so the latter is the higher percentage,  the balance goes the other way and you'd want to continue paying off the debt relatively slowly -- essentially treating it as a leveraged investment.  If you aren't sure, paying off the debt should probably be the default prefrence.
