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.  

Is it even possible to make a very low MAO with the cost of flood repairs incorporated (while the owners have insurance money on the way)?

That and being able to have a property analysis that I can customize with my logo, print and show to lenders I may work with.

Designing logos and starting LLC's doesn't produce cash flow.
