I am more inclined to try buy and hold, or buy with intent to sell after a few years.Key questions I have are: When is the best time to buy out here?

Proceed with cautious intent.  

The intent would then be to refinance to a conventional mortgage in 6mo-1yr.

However, I may not have made clear the intent of my post.

Hello,I'm hoping someone can give me advice on some ways to structure private money investment in our flipping business.My business partner and I formed a LLC with the intent of fixing and flipping houses.

Money Bags"like yourself :) Its seems a bit shady to try to skirt around the intent of the rules.

This way of loc/margin buying is very much my intention too.

Accordingly, there is no downside to electing to form a series LLC rather than a traditional LLC, even if there is no immediate intention to create series.Series LLCs began in Delaware in 1996, arrived in Texas in 2009, and are now available in thirteen states.

I assume State legislation would not interfere with the parties' clear intent for the contract to be assignable.I found the precedents you referred to on File Place. 

Would rather contact borrower to determine intentions without the "big FC"  first.
