Russell makes a good point that maybe refinancing would be a consideration in this case, but the other side of the coin is to consider an unsecured loan. IF you make a plan to pay it off within a reasonable amount of time it might make sense. For example, if you opened a new credit card that allowed 0% financing within the first year, and you could pay the total off within 12 months then you actually get a 'free' loan. The risk is that if you don't then your interest rate is very high, and a credit card debt is not tax deductible where the other loans I mentioned are tax deductible.
....just thought I'd mention it.
