That was a grand slam home run deal because it was purchased right even with those unknown issues.

Cheers, it's ballpark like algebra.You can't easily solve this:a + b + c + d + e = fBut you can easily solve this:44 + b + 23 + 13 + 48 = 155And, once you have solved that, you will likely be able to solve one with 2 unknowns, and work from there.

I think it's at least 50% chance that you'll lose money buying in an unknown inexpensive market.

But now I think I've overcome some of my 'unknowns' and I'm getting into a groove.

Keep in mind you'll never have all the information and there will always be unknowns and assumptions.

The unknown is, will they survive?

A lot of unknowns they need to figure out before contacting you.

To many unknowns, and often does not work out well for the investor.  

I've offered "as-is" several times but with the only contingency being sewer scope because it was the only remaining unknown.

@Greg P.There are a lot of unknowns in your proposition.
