I have a question about college financing and home cash-out refinancing. I have about $100,000 in federal and private student loans, and most of the interest rates are around 7 percent. My parents are interested in knowing if they can do a cash-out refinance on a second home that has no mortgage (because they paid it off) to pay off my student loans. Is this a good idea? With home loan rates around 3 percent, it seems to make sense. Any suggestions would be wonderful. Thank you.
