You want to make sure you're saving on a monthly basis and with the overall terms of the new loan. If you're currently in two mortgages, when you combine them, will you now pay a much lower rate compared to your current blended rate? Will you be subject to PMI? Etc...
You're next move should be to meet with a Loan Officer and go over your options. There's just too many other factors that come into play, it's best to meet with a professional and cover all necessary ground and go from there.
If you need someone, I'm always available to meet. Good luck!
