Don't be afraid to jump into the unknown and then figure it out along the way.

It is unknown and likely no way to identify the percentage of people that are type 1 to become type 2.

Just trying this price range, so length to sell is unknown.

Because I absorb the "scope-risk" they don't have to inflate their initial estimate and pad it for anything unknown, so I get usually lower bids upfront and it lowers the stress for the contractors.

My main question is how to due diligence on a property so you don't get stuck with buying some unknown lien or 2nd mortgage.

Plus, I'd estimate approx 85% of the homes in my area have septic systems and well water, which is a big unknown when purchasing foreclosures that have been winterized.

And the first thing I will demand is you call me "My Supreme Overloard of the known and unknown Galaxy". 

Those rare properties that do come up the broker likes to go with a seasoned buyer they have closed deals with before on multifamily versus an unknown.

I'm a firm believer that anyone presenting financials should account for the unknown.

Your tenant wanted out of the place for some unknown reason (and it wasn't due to mold).
