If you have held a 30-year mortgage for approximately 11-12 years, then you are paying more on the principal than a refinance which starts out all over again at a higher amount going to interest first. Then, the only time it would make sense to refinance is if you, indeed, were going to invest the money and earn a return greater than the net of tax deduction rate.
