Due to the major rush lately in the number of properties that are going to Auction, The Agent will usually offer and provided you with a copy of the pre-sale building report that was purchased by the sellers. Warning! It is not worth the paper it is written on! It is so important that you engage and pay for your own trusted building inspector to provide a unbiased house inspection survey and thorough building report for you to uncover any significant issues that will cost you heavily after settlement day. Once you have moved in, there will be no recourse on the vendors or the sellers engaged building inspection company.
My professional opinion and advice to you is to always engage your own building inspection company to provide you with piece of mind!
