That depends. If you decide to refinance your current mortgage, you may be able to obtain a lower interest rate, which means lower payments, and the possibility of a cash-out refinance.

If you are happy with the interest rate on your current mortgage, it makes more sense to consider a HEL or HELOC, especially since it is possible to refinance your first mortgage as well as your second in the future if interest rates do take a dip in your favor.

Obtaining an interest-only refinance is also a possibility. However, while an interest-only lowers your payments, it can also lower the equity in your home and, says CFA for bankrate, Don Taylor, "only makes sense for people who don't plan on being in the mortgage or house for a long time."
