<prompt> Human: We have a house mortgage of 30 years at 6.75. So far we are 11 years in and have paid off a little over half of the principle by making extra payments. We also have an excellent credit rating.Our mortgage company has offered us a refinance of the remaining principle at 10 years3 which would seriously reduce our payments and let us pay off the house faster were hoping to pay it off in 5 years. Were a little puzzled as to why they would offer us something out of the blue that would decrease the amount of money they would make off of us. We werent inquiring about a refinance, they contacted us and offered it to us. Many thanks in advance.  <response>: lots of people are refinancing right now because interest rates are so low. given your current interest rate, they probably assume youre shopping around. its better for them to keep your business by offering you a good refinance deal than to lose your business all together to a competitor.
