If you're buying a home anytime soon, here's
 some contrarian advice: Don't take out a fixed-rate mortgage. If you 
do, you're likely to pay more than you need to.
Instead, it often makes more sense to
 choose a floating-rate note, also known as an adjustable-rate mortgage.
 Even on a small mortgage, over time you'll save thousands of dollars. 
If you use the extra cash to pay down the loan, you'll save even more. See original story here.
