Thanks for your help, really appreciated.
My friends had nowhere to move on the settlement time, and so have bitten the bullet and got a contract for $525k. Their clever solicitor put a very good condition for approvals etc (as it is a new house) to be made available within 5 days. (Its a very good clause and if anybody is buying a new home (still under warranty) - happy to make it available.
It would appear that, after signing contract with said condition, the vendor cannot meet the condition. Apparently there is a pergola that "may not" be approved by council. The vendor had somebody else install and don't know if approval was sought!
Straight away there is an out should my friends need one, but they will wait and see what is given to their solicitor to see if it is worth proceeding or not.
So it would seem one hurdle down, and a couple more to go, council approval and building, BSA, pool and fencing approvals, and then the valuation.
I shall let you know how they get on. Once again, thanks for the help
