so it seems that so far 2/3 of my issues really were not issues and i have done the wrong thing by this vendor ( unknown to me of course).
Splade,
At the end of the day the only thing that has gone wrong (if that's the correct term) is that you signed the contract without knowing the full situation.
Almost anything can be included within the terms of the contract and as the purchaser you generally have the upperhand so if you were aware of any issues they could have been included in the contract prior to signing. Atleast this experience puts you in a better position for your next deal.
Don't know if you can break the contract without penalty (subject to finance is fairly thin) but wish you well.
Personally I have no experience with commercial (apart from leasing) and therefor applaud your courage in giving it a go.
Interested in knowing if you have had much experience in the residential side of property.
Hope everything turns out as you desire.
Regards
Andrew
