<p>EDIT: My post (below) was crossposted with the last one from PIOH!</p>
<p>From OP’s posts on this thread, the summary:</p>
<p>H & W are both in their early 40’s.</p>
<p>Sounds like they refinanced 5 years ago into a 30 yr fixed mtg, at 5% interest. They have 25 yrs to go.</p>
<p>They have 50% equity in their home at today’s market rates.</p>
<p>They have the remaining 50% equity in cash in the bank, which they have had for the last 5 years, and instead of most of us who kept (i.e, lost) our money in the stock market, they had it earning 5% in a CD. Now the CDs have matured and are earning 2% interest.</p>
<p>They have calculated that if they eliminate their mortgage, the INTEREST portion of their mortgage payment will be equal to the difference between MIT tuition and the tuition that they have been paying for their D at her elite private high school.</p>
<p>They will apply the PRINCIPAL portion of their eliminated mortgage payment towards retirement.</p>
<p>After D graduates from MIT (unless they are paying tuition for her medical school), they will start applying the INTEREST PLUS PRINCIPAL portion of their eliminated mortgage payment towards retirement.</p>
<p>Under all circumstances they will have at least 12-15 months’ living expenses sitting in cash in the bank. (Perhaps they haven’t calculated COBRA costs. I am pretty sure OP is math savvy enough to have factored in property tax and insurance costs).</p>
<p>One could go further and make more detailed calculations based on the posted numbers and figure out the exact dollar amounts involved, but OP’s family seems to be doing quite well financially and does not sound like a typical ‘living beyond their means’ family. They seem to have pretty good savings habits.</p>
<p>The financial aid angle here seems to be just a distractor. OP knows that his daughter will be full-pay at MIT as long as he (and maybe his wife) is/are employed. His calculations seem to suggest that his D would qualify for more aid if he pays off his mortgage rather than just sits on his cash. I have no idea if he is misreading the MIT FinAid calculator. But since he still has his job and if he loses it he may well find another one before his D graduates, this may not be the most important consideration. </p>
<p>Blossom’s advice about planning for contingencies is good. Everyone should consider retirement, long term disability, long term care insurance, life insurance, etc. Others have also given good advice.</p>
<p>But none of the advice addresses OP’s original dilemma: What to do with all this money sitting in the bank if you are risk-averse and you won’t consider more risky investments like stocks or bonds? Paying off the mortgage does not seem like such a terrible idea. I have at least one similarly risk-averse relative who paid off his mortgage in his 40’s- and never regretted it.</p>
