Pre- purchase Building Inspections - some sort of scam ?
	
	
		Move on and wait for another potential buyer.  If a buyer wants a reason not to buy then they can also move on - it is a match that is never going to work out.
With the exception of getting a termite inspection (a must in WA), all the places I have bought and sold I never once engaged someone to do a pre-purchase inspection, or had a buyer want to do the same prior to buying.
But have had the same issue once with a Rangie sale - buyer insisted on a LR Indy to do an inspection.  Indy rocks up, takes the Rangie for a drive with the potential buyer and I, does some donuts in a gravel car park (it was a fun drive), and then tells the potential buyer all that was wrong with it.   It was a 13 year old car - I had already pointed out its faults.
I said that is fine - if it is not right for you move on as I am happy to keep it and to be honest it deserves a better home.
Same again with a Disco sale and this time a different LR Indy doing the inspection was from the garage that had just done some work for me a few weeks earlier. But then the owner of the garage doing the inspection then criticised the recent repair saying it was not good and would fail again.
I said thanks - now your guys did the repair so let’s talk about what you will do to fix it.  They sorted it but I never went back to them.  The potential buyer wasn’t to impressed either.
