Add ons can come up with unknowns but you don't want to pay for things that you thought were part original agreement.Another thing that typically isn't correct in older homes and is fairly easy to detect is ventilation.

The remaining partner held the majority of the equity (actual split unknown), but was a silent partner who did almost no work or decision making himself (nice, but super busy guy). 

The HOA is an unknown at this point, hopefully I will have the the answer to that later today.

Either the seller isn't motivated enough to sell to you at a discount and is willing to list to get more even if it means an unknown price and everything that goes along with selling through listing.

So it will be a good rental place.How do I get confidence that there are no unknown risks.

I mean, which is better: "I have a house with unknown foundation issues." or "I have a house with these specific issues with the foundation that will cost $x to fix."

I went over any area I felt I was relatively weak in (of the 30 sections, roughly 10 or so are what I really needed to go over)Crammed ~ Went and took the test ~ and passed both portions on the first try.Don't get worked up ~ If you fail or only pass 1 of the 2, at least the UNKNOWN is over with!  

That seems like a plan for disaster to have that many different unknown people living together under one roof. 

Unknown!  

Write down everything it needs then when you get home price out everything then add a few more thousand for the unknowns.
