Legal concerns with buying rentals using HELOC on primary res?

[Ronald Lee]

Newbie investor here. I was talking to my CPA on possibly taking a line of credit on my primary residence to fund my rental property purchases, which I'm planning to do through a LLC. She said with HELOC, technically the investment property would be purchased using my primary residence as collateral, so the LLC will not protect my personal asset from potential lawsuit. Wondering if anyone who's doing something similar has heard of this? The articles I find don't mention this in the cons part of using HELOC. I don't have enough cash on hand, and I'm considering the HELOC option so I have more control when I actually need the funds. Any feedback is appreciated :)
