My idea for wanting the HELOC is to have access to funds for future deals.  

Investment Info:Small multi-family (2-4 units) buy & hold investment. 3 unit apartment complex What made you interested in investing in this type of deal?

Quote from @William Dorrough: I currently either purchase and value add large scale multifamily properties or develop, and build ground up my issue with scaling is we have done this without brining in investors i have a great deal flow with a good track record im really looking to do more i have the capacity but have the need for more capital in one way or another  Scaling without investors can be tough, especially in multifamily.

And you will keep missing deals if you don't take action.

It's a super affordable real estate market where you can still find deals that hit the 1% rule and positive cash flow/great cap rates.

That got me to learn contractors, negotiation, and how to analysis deals too. 

However, a great deal came along my way.

Better to make that mistake, and buy another deal, than to not bought the deal.  

Based on your description, it sounds like you would violate the self-dealing rule and could put your SDIRA at risk. 

My target asset class is multifamily and I just had an LOI accepted on a six unit deal in South Jersey.
