Home equity loan

I have been paying down my debt using the snowball method. I'm making great headway and have cut my debt load in half in 3 years. I'm at a point where I need to choose between a home-equity loan with a variable rate (currently at 4.24 percent but eligible for tax deductions) and a car loan at 3.5 percent fixed. Which makes more sense to pay down? Scott, Chatham, MI

Hello. I'm 50 and single. I have a 15-year mortgage at 3.5 percent. My income is more than $80,000. I have a Roth and I am maximizing my company's 403(b) account. I have no credit card debt -- no debt in general except the mortgage, so I don't have a lot of write-offs. Does it make sense to get an equity loan and finish my basement so I can get a bigger write-off on taxes while investing in my home, or should I continue to just sock money away because it is better to not have debt? Thanks. Lisa, Salt Lake City, UT

We have 7 years left to go to finish paying off our mortgage and we have a manageable amount of home equity borrowing. How wise or risky would it be to consolidate that, borrowing at a lower rate, if the new loan would be a home-equity loan? That's the advice we're hearing from our bank and the stated rate should be lower than the rates we have on our existing mortgage and home-equity borrowing. Is there a reason to think twice about this? Thanks! John, St. Paul, MN
