normally, it's not worth refinancing if you are only going to be in the home for a short time.
However, you may be the exception as your interest rate is 6.25 and 30 year fixed rate mortgages are WAY lower than that these days.
You'll have to do the math and determine if the reduced payments justify the closing costs you have to pay. It may in this situation.
otherwise, don't refinance and get a HELOC. the closing costs are much cheaper.
