Correct me if I'm wrong but I took your post to mean, tracking all major things that incorporate, or effect NOI is wise because ultimately a large component on your IRR strategy will be based off the exit and or refinance, which obviously is the factor that you as an investor can control when considering the capitalized valuation of the investment.  

Greetings BP,I'm setting up my business and I need someone to point me in the right direction for my Articles of Incorporation.

Example: 30/70 split between Jim Brown and his IRAHow the property purchase is recorded: Jim Brown, an undivided 30% interest and IRA Services Trust Company CFBO Jim Brown , an undivided 70% interest.Compliance NotesThe percentage of ownership is determined by how much funds each party invests at time of real estate purchase.All expenses and income are shared based on the ownership percentages.No debt financing can be incorporate under a tenancy in common (TIC) transaction; otherwise, the transaction will be deemed a prohibited transaction. 

I agree with @Nick Britton invest in an education, and focus on strategy that incorporates no money, no credit techniques to start your business. 

When I am doing things like building my website, creating my new business cards how I do incorporated what I can do into one title?  

I was fortunate to acquire a great deal of experience and learnings during the period of time, but my wife and I chose to make a move back to the midwest and I pursued a career in Corporate Finance pre-bust in 2006.  

As splitting the cash flow a bunch of ways makes no sense, what are some successful strategies people have used to incorporate other investors into your business?

The "business name" is not registered officially or incorporated in any way. 

I'm pushing thirty years old and my background is in corporate finance and valuation.

You already have experience with Flips so just incorporate that into your strategy.
