<prompt> Human: So I thought Id ask the great and powerful PersonalFinance.I have a house I bought a few years ago, appraised for 115k - currently owe 95k and some change. Im about 4k from being at 80 LTV ratio, at which point I can pay for a reappraisal and then suddenly be saving 80month from PMI. My logic is this -- saving 80month in that insurance payment is a far better return than the 1 I would be getting by that money sitting in the bank. So it should be a no brainer to go ahead and plop down the money and get PMI wiped outI had already planned on making extra payments starting in 2016 500month on top but why waste 6 months screwing around working towards it when I could just do it now?It wouldnt deplete my savings account and Id still have an easy 6 month emergency fund. Not to mention that any extra principal payment would also save quite the nice chunk vs paying it out in the coming years I know its only 4K one time payment but the extra payment calculators online say even just a 1 time payment in this manner, would ave me around 9200 dollars in interest over the 30 year term if I took the long route. Thoughts?  <response>: Your last paragraph answered your question.
