I went to view an apartment last week in the city centre. When I called up to arrange the viewing, the latest offer was 400k. When I met the agent the latest offer was 405k "that the vendors were considering".
However, at the viewing, the agent gave me a brochure which stated that the pricing was "offers in excess of 375k".
From what I've heard, it helps if you are able to close quickly on the sale (particularly if you are buying a 2nd hand house and the vendors want to move on quickly). You'd have a better chance of getting an offer that was close to the asking price accepted.
