Sweep strategy with HELOC?

[Michael McCarthy]

I have two rentals that I bought in the last year, both purchased under a HELOC. I just refinanced one. After reading @davevanhorns email mentioned paying down mortgages with sweep accounts. I can't find much information about it in detail. Do I transfer my rent that I get each month onto my HELOC and then pay the bills from that. What is the best strategy here?
