I just started reading David Green's book and realized he says you have to pay cash....I'm in contract on a duplex and plan to use traditional financing, considering a 3/1 ARM and then will rehab, and get a HELOC.

Another option is to get a heloc on your primary and do the brrr method and keep paying your equity back and you will still pay your house off within 15 years with the lower rate.

If it were me, I'd take out HELOCs on your investment properties and use that to fund additional investments.

Has anyone ever heard of a HELOC or Cash Out Finance that can be closed on remotely?

85% seemed a bit high to me, yet checking the article in 2009 the limit was 95%......I guess I should know better than to expect fiscal responsibility from people.Banks kinda figured this out a while ago with HELOCs when they began doing "benchtop" appraisals that are very conservative limiting borrower allowance to access equity. 

We also have a HELOC on our primary open and owe about the same amount we made on our rental.

No additional risk as no new debt is accumulated.COA2 (medium risk): Take out HELOC (or cash our refi) from current rental properties.

I’m using my HELOC for the down payment, I’m well aware of the risk and it doesn’t bother me.

If you refi, and don't payoff the HELOC...what is the cash flow then? 

Careful of the interest rate however as some HELOC interest rates start low and change after a certain term.
