It's that time again, all my friends are talking about refinancing because the interest rate has been dropping. I refinance my mortgage back in November... barely on my 4th payment on the new 6%/30yr loan. I am unsure what the rate is at right now (a friend said it was at 5.5%, but she's an unreliable source), but at what rate would it be worth it for me to refinance again? I recall someone on here is a mortgage broker, any input or advice?
