If there is even one passive investor they need disclosures that would be enumerated in some form of documentation like an offering circular.  

Like you said, it can get very complicated very fast, and that's when mistakes happen (faulty logic, bad formulas, circular references, etc).If you're analyzing a portfolio or how a potential property might fit into your portfolio, or if a single investment requires that rigorous level of analysis (multiple scenarios, blended scenarios), you might need something more complex.  

I have a general tool bag, a plumbing bag, and a bag for all my small circular saw, jig saw, multi-tool.I use my general tool bag the most.

MLS has circular distance tool and sort scheme.

He has circular saws, sawzalls, multi tools and a whole host of other tools battery powered.

A little bit of a circular argument in my opinion.

Do you want to make $10 an hour with a hammer and a circular saw or $10K an hour negotiating a deal?

Curious how the dog operated the circular saw without opposable thumbs! 

Appliances are the real hiding spaces, too, so I put some of the circular poisons on the backsides of these.

If I was a betting man, and had only this picture to make my bet, I would say that this is an freeze-thaw crack - pressure from the soil outside the foundation pushing inward (hence the semi-circular pattern - not stair-step, not vertical or horizontal), so it might be a matter of some exterior grading/drainage work followed by an epoxy grout crack filler repair to remove moisture.I recommend you get it checked out - put a contingency in the contract that covers your bases, so you're only out a couple hundred bucks for a structural inspector.
