We bought a home in FEBRUARY of 2005 the payments are pretty high we have a fixed 30 years mortgage at 6.125 and we are trying to reduce our mortgage payments, we are being offerd a 7 years fixed at 5.37 and a 10 years fixed at 6.125 both which is interest only which is the best refinance plan or should we stay with our present mortgage of 6.125 for 30 years.
