HELOC as down payment question

[Brendon Seiffert]

Hey guys!

I am in the process of getting a HELOC on my home now, but my question is how do you use a HELOC when using it as a downpayment?

I am just trying to figure out that if I take out $30k on mine, and use that as a downpayment on a $100k house that rents for $1000 a month, isnt that HELCOC payment then eating into my cashflow for the 25 year life of that loan? Or should I pay it off early, and reuse it? 

Not new to rentals, but new to HELOCs and am sort of lost.
