<prompt> Human: I am 43 and we have 210K pending on our home mortgage 13 yrs remaining at 4. I also have 200K in cash in a CDmoney market account making no more than 1.5. I am wondering if it is a wise move to pay off the house? On the surface it seems obvious - why pay 4 when you have money earning on 1.5 but there are a few things I worry about,1. Liquid cash is an asset which can be used immediately medical issue, investment opportunity etc.2. Losing the interest deduction on my federal taxes3. Not having a cash buffer at least having to build it up againThoughts?  <response>: Honestly, Id throw 150k at the mortgage, even if it makes financial sense to invest it in the market since market returns are likely higher than 4. And then pay extra on your mortage, and have it done in the next year or two. Having a fully owned asset is a wonderful thing. From what it sounds like, youre also doing very well with your retirement and money market accounts.And FYI, put that money in a High Yield savings account like Ally, youd be making more than in that CD 1.75, and you can withdraw it faster.
