This means that you can’t negotiate a different price based on an inspection afterwards. Once you get to this point, the contract cannot be subject to any conditions.
Even if you think you might not buy it, it is far better for you to bid when you are fully informed. Once the auction begins, it’s much too late.
Remember, auctions have no cooling off period. Once you win, the property (and any of its problems) are yours.
If you are seriously considering the property, inspect now.
