I know this question has been asked a lot, but after doing the math, I'm still not sure what's the makes the most sense. I have a 30-year mortgage @ 5.5%. There's about seven years remaining on the loan. Even though the amount I pay monthly as interest has gone done steadily every year as the principal gets paid down, I still pay almost half the monthly mortgage as interest. I have an IRA that requires RMD withdrawals with about five more years left before it has to be fully depleted. The remaining total is roughly about the same as my mortgage's current balance.
While the market is still doing well, should I withdraw all the remaining funds in the IRA and use them to pay off my mortgage now? Or, continue to earn on the investments in the IRA while also continuing to make monthly mortgage payments until it's paid off in seven years?
