Pay mortgage principle vs saving money or mutual funds?

[ledbetter]

Hi Financial Advice Forum,

I been arguing with my husband aver an ongoing issue. She wants me to pay $500 monthly extra towards mortgage principle which I think it is not worth it. Our conversation and debate went nowhere because we always argue because she is always right (or thinks that she is). I told her to call Saxon mortgage company and see how many years we actually going to pay it off sooner by paying a $500 per month extra for the principle - then she got pissed. I then gave her a scenerio saying instead of paying an extra $500 every month, why don't we save that money in the bank and then pay to the mortgage company every 5 or ten years. That way at least we get some interest - she got mad by saying the bank only offers 3% while the mortgage is 6.25%. I need advice here. I still don't see paying $500 extra to Saxon mortgage coompany will do much good. I rather save those money in a saving acct or better yet in a mutual fund acct. What the pros and cons on this issue?
