On the contrary. If you just have the infamous "Homebuyers report", the
title of which is calculated to deceive, it will not pick up any defects
that may have occurred by botched building etc. The problem and the
associated bureaucray will re-appear when you come to sell the property. Far
better to let someone else have the hassle! Of course you can only disclose
facts you know but in this case the OP does know them.

Yes, that's why I suggested that "the less you know about the house
you're buying the better".
