I have a tracker interest only mortgage taken out in August 2007 [ 120,000 euros] and in October 2007 [20,000] The current rate of interest is 2.9%My monthly payments are 338 euros. It is an ivestment property which I have rented out since 2007. As it is a rented property I get tax relief on the interest payments. My question is should I pay off the mortgage now? I have funds to pay it off. If I leave the funds in savings am I at a loss.? The fact that I get tax relief on the interest paid, I am trying to gauge how much of a loss this would be if I pay off mortgage now.
