you should consider a new loan program just being introduced to the states by a company call CMG, but it is backed by GMAC. It is hugely popular in Australia and becoming so here also. I have a link to the videos and calculator at my office and I will post them here tomorrow, but in short it lets you pay off your house in less then ten years, without changing your spending habits at all.
Is this the great rip off where you buy a $3,500 piece of software (rip off signal one), sold in a multi level marketing scheme (signal two) and have a line of credit where they kind of forget the interest due in the sales pitch. The only way to pay a mortgage off in ten years is to pay extra principal which you don't need a software package to do. Why not invest in your 401k or ira instead of paying your mortgage off?.
