House Hunting Pet Hates – Price on Application

I’m still trawling property listings sites on a semi-daily basis and I’ve now got alerts setup with Daft.ie

Of course buying a house involves some basic economics. You have a buyer (me) and a seller (either a previous owner or a developer). For the seller to be able to make their money they need to be able to find a buyer who either has the money required or the ability to get their hands on it.

So why on earth would anyone list a house with the mysterious “price on application”?

If I have a budget of say 300k there is no point in me looking at a house listed at 400k.

What can possibly be gained by listing houses without guideline pricing?

Maybe I’m missing something essential and basic from the “big picture”
