It's not so much that everything is overpriced generally that you need to be thinking about, it's more than the statistics (look at the latest Permanent TSB/ESRI house price index) are showing that prices are dropping. Maybe not by much overall but you might be pleasantly surprised to see how strong your position is. We're just saying don't be worried by the 'price on application' thing AND don't assume that it isn't possible to offer under the AMV, especially if renovation is needed.
It can depend on the seller of course - some sellers, no matter what the market situation will hang on in there for the best price available, because they desperately need a certain amount, they really believe that someone will pay what they want, or they're in no hurry to sell and can afford to wait for the perfect buyer! But there are also sellers who will knock money off the price in order to get a quick sale or because they need to close on their next property.
It can be considered a buyers market at the moment - you've got power, so use it!
