HELOC or not to HELOC

[Wes Brumit]

I've recently seen people giving advise to take out a HELOC as a means to pay your normal everyday expenditures including bills, and at the same time, taking your paycheck from job and applying it every month towards your mortgage payment. The goal is to pay off your mortgage in 4-10 years as opposed to just making the normal payment for another 20+ years. Has anyone done this? What are pros and cons? I did the calculation on my primary property and would have mine paid off in 4.3 yrs instead of 13. Looking for more input before I make a decision
