Should we prepay our private student loans, given our particular profile?
You're in good shape as long as your income stays. Your only variable-rate debt now is your private student loan.  I think you'd be wise to pay that down first, and you sense that already. Worst-case, in the event of a bankruptcy, student loans usually cannot be discharged, so that isn't a way out. Once that loan is gone, apply what you were paying to your other student loan to knock that out. You might investigate refinancing your home (to another 30-year fixed).  You may be able to shave a half-percent off if your credit is stellar.  Given the size of the mortgage, this could be several thousand out of pocket, so consider that when figuring out potential payback time. Consider using any "free time" to starting up a side business (I'm assuming you both have day jobs but that may not be a correct assumption).  Start with what you know well.  You and your wife are experts in something, and have passion about something.  Go with that.  Use the extra income from that to either pay down your debts faster, or just reinvest in the business so that you can offset the income on your taxes. Again, you're in good shape.  Just do what you can to protect and grow your income streams.
