@Jeff Graves we took out a HELOC on our home in Hawaii and paid that same home off with it. We got our HELOC through Bank of Hawaii. Their customer service and closing time is a little slow but with an introductory rate of 1.75% at 85% LTV you can't beat it. We initially got a PLOC through Hawaii State Federal Credit union to pay down some principal to have enough equity to be able to get the HELOC. Once we pulled the trigger on the HELOC we actually ended up paying off the home, the PLOC, and our car. We use our HELOC like a checking account and deposit all our income into it and since we pay next to nothing in interest we're seriously impacting our principal. And remember, since it's a line of credit, as you pay it down that money becomes available again to invest in other properties. Back to your original question, our home in Hawaii used to be our primary residence but we moved to Texas a couple years ago. We closed our HELOC about 6 months ago and the banks in Hawaii are ok with opening HELOC's on investment properties.
Aloha!
