Thanks guys,
Definitely some food for thought. Guess it's really now a wait and see approach to see what the report comes back with.
On a related note, a friend of mine recently purchased a property where the house was lifted and foundations/piles all redone - I think this was done privately rather than through EQC/onsolds. I guess if anything, it shows that the cost to do that work stacked up financially to the seller and potentially not in the same realm as demolishing and rebuilding..
