I understand that, but in effect the yield on the bill paying money by reducing the interest to be paid on the heloc vs. getting a pittance in checking acct. is a net benefit.

Let me see here.. I take out money at 8+%(cost) interest rate to pay down a 6%(cost) loan at an accelerated rate to avoid carrying money in my checking account at 4%(profit) yield?

Doesn’t make sense. See my notes earlier at paying down the most expensive money first. This is normally the procedure to get out of debt. You don’t want to increase the amount in a more expensive source of money. In the above scenario, you want to pay down the HELOC first and then the mortgage because the HELOC is a more expensive source of money.
