Using HELOC to pay off mortgage or buy investment property?

[Kazi Islam]

Recently, I came across this program called, "Replace your mortgage" by Michael Lush. During my first call, they collected financial information and I was told I could refinance my existing mortgage into a HELOC and use it to pay off my mortgage in 10 years or so. I can also use the HELOC as my checking account as well. In order to pay off the mortgage in 10 years' time frame, I was told I would have to put all my savings and checking account funds into HELOC. I am intrigued by this idea but at the same time bit skeptical. Anyone here is familiar with this program?

Also, would it be wise to use HELOC to pay off the mortgage or use my savings account fund to buy an investment property? Thanks.
