I owe $223K on a 30 yr fixed at 5.675%. At what percent would it be cost effective to refinance.I am considering refinancing to a a 15 year fixed if the rates go low enough. My credit score is 816 and equity in the home is 45%. I owe nothing on credit cars and have No car payments and no other debts. What rate would be available to me for a 15 year loan and what would I expect to pay in points/closing costs. I'm trying to calculate the cost/benefit of refinancing.
