Thanks for the reply! Yes, my better half was saying that if the building gets reported then we would have to donate 30% to the government; not sure how that would work in reality and also very unlikely if the building has already been there for 16 years.
Anyway, it sold last night so no chance now. We’ll probably first sell our current place first and I’m now on the lookout for townhouses as the public space ratio is tiny and the interior spaces are huge.
