I have had a few home purchases in the past 10 years but have never refinanced. My current home is an FHA loan that has been paid on for 5 years. Its interest rate fixed 30 year in 1998 was 7.25%. I recently looked into refinancing with the FHA streamline process, less paperwork and easier to do. I am locked in at a fixed 30 year rate of 5.75% on the new loan. My question is that if I take my current monthly payment of P&I and escrow I am at $954.00 with 25 years 300 payments left. With the new note I will be at $830.00 P&I and escrow but will have 360 or a full 30 years again to pay. Here in lies my question?? If I take the simple math caculation of 300 payments left at $954.00 and 360 of the new rate....it comes up not making much $$$ difference. My closing costs and prepaids on the new note total about 2.5%. I do any refianace calculators and it says it is a good move to go with the new rate but the simple math shows otherwise. Could some please explain what I am missing as far as compound interest or whatever it is that makes this a wise financial decision! KARMA to anyone that tells me what I am missing. Thanks in advance!
