Still can't find the COA after turning the house upside down! What makes it worse is I can picture it in my head! Never mind.
I'm going to put my head in the lion's mouth and ask you guys how much you think it might be worth without the COA! Just a ballpark figure would be fine. I can then decide if it's worth selling it or if I'll just keep it until I unearth the COA in 20 years time looking for something else!
