Generally i'd agree with everything in Spudz post but the last two months have seen -according to CSO- an increase in apt prices in Dublin.
So, if you are talking about Dublin then perhaps the auctioneer and/or vendor are hoping that this recent upward trend will continue -and therefore they'll wait a while before accepting what they presently believe is too low an offer.
The CSO figures for May will be out in a few days and if they show another increase then I reckon that some Dublin vendors may get a bit over-optimistic and,possibly, greedy and thus expect higher offers.
None of which information helps in the slightest. Sorry.
But, as Spudz says, if you want a three bed don't compromise on a two-bed. Apt living can get claustrophobic especially if you want ,say, a study and/or room to invite guests.
