My husband and I just refinanced our house at a great rate (15-year fixed mortgage at 2.875 percent). Our house payment is low and we can afford to pay more each month. Would the best use of our money be to pay down the principal on this low-interest loan or put extra away for retirement or for our children's college fund? We have two young children and are in our late 20s/early 30s. Thanks for your help! Katie, Helena, MT

I'm putting the max allowed in my retirement accounts, and it's invested fairly conservatively in index funds. I lost a bunch of money in the tech stock crash in the early 2000s, which makes me hesitant to dump more money in the stock market. I own an apartment and don't really want more exposure to real estate, either. I'm starting to build up enough cash that I don't want to just leave it in my savings account. The only debt I have is my mortgage, and while I have decreased the balance on it, the interest rate is so low that it seems like there must be something better I can do with the cash. Any suggestions? Kira, Washington DC

Outside of my 403(b) Base Program, which my employer matches 10% to my 5%, how much should I sock away in a 403(b) Supplemental? Currently, I contribute 5% to a 403(b) Supplemental, for a total of 20% of 110% of my paycheck. I fully fund a ROTH IRA every year, so I am wondering if I should be saving more of my paycheck to a more liquid asset. Michael, Haslett, MI
