Suze: Refinancing absolutely makes sense! Mortgage rates today are more than two percentage points lower than yours, so you can indeed save plenty. But your mistake is in assuming you should refinance into another 30-year mortgage and set back the clock on your debt. I want to encourage you—okay, challenge you—to refinance into a 15-year mortgage instead.
Based on what you told me, I'm assuming your current mortgage cost is in the vicinity of $1,430 a month. If you have good credit, you can get a 15-year mortgage at, say, 3.25 percent interest and pay just $130 more a month. Where's the deal in that, you ask? Well, rather than focusing on what you can save today, set your sights down the line: A shorter payback period reduces the amount of interest you pay over the life of the loan. If you refinance with a 30-year term, you're looking at $160,000 in total interest. On the 15-year plan, that total goes down to $59,000! Plus, you'll have the mortgage paid off 11 years ahead of your current pace, and in half the time it would take with a new 30-year mortgage.
To your point that your pension could cover your mortgage payments once you've retired, keep in mind that other expenses, like medical bills, will inevitably be creeping up then. If your pension isn't earmarked for the mortgage, you can use that monthly check for anything you might need.
