Just had a similar situation this weekend Boomtown. Believe me, other buyer didnt exist. We had looked at this house 3 days before auction, when they said they had an investor interested who wouldnt be back in town till day of auction. Night before auction we had another look and lo there is the investor looking too. We spoke to tenants who said we were the only ones who had inspected the whole marketing time. Day of auction there are two other bidders, one constantly on phone. We registered, asked no questions, guy at open says are there any special conditions. Another guy (presumably the agent who had bought in the 'investor') read out the conditions, totally and only looking at us ???
Then when they started the bidding and we didnt bid, the investor looked at us and said, did we want to bid ????? Said we would leave it to him, so he opened, the other guy on the phone then shot it up $40K ???? (who does that??), then the agent came round to us and said we should bid, then the auctioneer actually said to us ' you are registered why arent you bidding ??? I said no I think you (thevinvestor) own it at this stage. They didnt like us at all. It was passed in on a vendor bid - surprise, surprise. We will sit and wait till they meet the market (there is no market here at this time!)
