Nicholas, welcome to Bigger Pockets and thanks for posting.

The vast majority of these units I purchased using private financing with $0 out of pocket. 

Only "CASH OUT" of your IRA in cash of an emergency or you are at retirement age. 

if the second buyer is paying cash then your done they pay your off and your first note.. off to the next one..

While none of these options allow for immediate cash flow on the property (we are on the northern CA coast) the ARMS would allow us to break even.

This is mostly because they can't provide the high level of service that Buyers deserve and for now Sellers are still generally paying. 

Once the property is sold we will be able to pay off the HELOC and will also have further funds coming in the following year.

I could envision them refusing to disburse funds until the LLC is reinstated.There may be a way to transfer ownership of the account, but it is probably just easier to move the money.

My concern is that you seem to be out of country.

I took out a HELCO on my primary - I understand not cash flowing - could have taken out a lot more but only took 50%.
