With interest rates at historic lows, there seems to be a pretty simple answer. Yes! …Probably. There as an old rule of thumb that said if you can reduce your interest rate by 1.5%, it is worth refinancing. Loan officers often tell you about the “monthly cash flow savings” from refinancing, calculating that if you’ll save $200/month off your current payment and their fee is $2,400, that you get your “money back” in only 12 months. However, what they sometimes fail to mention is the fact that you’ve often extended the length of your loan to get that cash flow savings. The only savings that really matter is the interest savings you'll reap over the life of the loan.
