I'm currently working on building my retirement savings and looking into the best ways to secure my future. I've got a question about my mortgage, which has a 6.25% interest rate. I'm wondering, why would it make sense to dip into my retirement funds to pay off this loan? After all, my diversified portfolio is expected to bring in returns of 7-9%. Plus, I still get to enjoy that mortgage interest tax deduction. It's kind of a tough call, isn't it?
