Which option do you see fitting best?

[Matt Lawrence]

I have 3 options to use as my down payment towards my next SFR. HELOC from my primary home, which I initially leaned towards thanks to David Van Horn's opinion, with a 5.5% variable rate & I believe paid back over 3 years. Never done this before so still learning the ins & outs. Private money which would be approx a 15k note that I would pay back @7% over 5 years making it a lower monthly payment - Use my own money. For arguments sake
