Not saying the valuer is wrong, but I would have thought the reserve price is locked in after Channel 9 has done all their accounting hence making sure they get their cost back ( and profit as well ) so anything above the contestants get. So I think 9 screwed them because they are greedy, if they lower the reserve the contestant wouldn't have been so disappointed. And the fact that their wasn't much bidder left that didn't help.
You know, the chinese who was bidding wasn't too keen on the boys or Chris and Jenna, they are more keen on M & K apartment thats why they didn't go further with the first two. M & K layout and design are winners for the Chinese, chinese loves that style and if there was another chinese bidder there...they would have done well.
