<prompt> Human: I have six years in on my mortgage and we pay twice a month so it eats at the equity faster. 5 mortgage, should go a little lower. Not sure how much lower exactly. Anyways, is it always a good idea to get a lower mortgage rate? I kind of want this mortgage gone by the time my kids are ready for college.  <response>: Well there is usually refinancing costs, so make sure the reduction in interest makes up for it.
