<prompt> Human: Im sure this has been asked before, but I couldnt find it. I have often heard the argument that you lose a tax advantage when you pay off your mortgage early since interest on your mortgage is tax deductible.How is it beneficial to pay 1 interest to get back 0.30 in taxes?Im assuming that you could invest that extra money to possibly gain a higher effective interest...but is that ever worth the risk for gains of a percent or two?EDIT Next question is, if it is advantageous to pay off the house early to save those interest dollars, then would it also be better to put all non-matched, post-tax investments into the house payments instead?  <response>: My opinion is to pay the home off early. I look at it as you will have a place to live vs counting on a good investment return. I still have investments though.
