My mortgage is at 4% with a monthly payment of about $ 1250. I pay $ 1800 per month on it. The current outstanding balance is about $ 162,000 and the house is worth about $ 501,000. I could write a check tomorrow to pay off the house, but since my goal is to have it paid off at retirement (in the next 8-9 years, depending), I figure we will keep on making payments and get somewhat of a mortgage deduction for the taxes. I like to have a healthy amount of cash money in the bank, crappy ROI these days notwithstanding. I would not mind earning more than 0.01% interest or so.
