Here is a good question from a Money Crasher’s reader that I thought I would share with everyone, because some of you may have the same question. Remember, don’t take my advice as gospel. Verify it with other people you trust in your life. I answer questions how I would do it and what I feel is the best thing for your personal finances.

My wife and I currently have a 6.125% 1st (30 year fixed) and a 6.65% 2nd (5 year arm interest only) (80/20 loan) mortgage on our homestead, and we also have student loans which have been consolidated at 3.75% fixed.

We have a sufficient emergency fund, invest in our firms’ 401(k) programs and have no credit card or car loans. If we want to allocate addition funds to pay down either our mortgages or student loans. Which one should we do? Oh, we also do not qualify to take student loan interest as a tax deduction anymore.

First of all, I want to congratulate you for doing so well with your money so far. You’ve got great interest rates on your mortgages and on your consolidated student loans. You’ve got no other credit card or car loan debt, which is great! You’ve also got an emergency fund, which is what I would have told you to do (build one up first) before you start paying off any of these debts.

The only thing that concerns me a little bit is the 5/1 ARM interest only 2nd mortgage. You did not indicate how long you’ve had the ARM, if you’ve had it for a couple of years, then the interest rate will soon start to adjust and raise your payment on it. I would say that this is the riskiest debt that you have, and you should pay it off first, as fast as possible. Then, start paying off your student loans. Save the 1st mortgage for last. Even though it has a higher interest rate than the student loans, it’s a low, fixed rate and you’ve got something to show for that debt - your house! The ARM can make your life miserable if you let it stick around for too long, so I would work hard at paying it off first, because you’ll be building equity into your home and getting rid of a lot of risk in your life.

Does anyone else have any suggestions for this couple? Post it in a comment!
