Yes it does, I paid off 2 of em, still rent out the first house as in investment. It's really nice because if something happens to me, we will still always have a home to live in, we use the extra dough to get our last kid through college now. I ain't big on refinancing stuff, look at the long term interest you pay, all loaded up front so by the end of the loan you are paying principle and it ain't worth paying it off then. The extra $50 or $60 a month will help a lot in the end. Our first house was a 30 year mortage...we paid extra on it to get it down sooner...they SUCK.... get a 15 year mortgage, compare how many thousands of dollars you will save over the long haul, more than you will make in investments.
Banks and RE's want you to get 30 and even 40 year loans, don't do it, think, compare, don't be their sucker.
And don't get that life insurance policy they often add on them, you can get much better term policies for lots more money for the same amt they want to charge you.
