I've got pages that do the same, and I'd suspect it's down to the linkage anchor text, try an allinanchor:Keyword search on G and see where your site/competition turn up, they should roughly mirror the positions in the organic results.

Take Huntforproperty.ie, you use "Irish property" in you sig here so:

allinanchor:irish property - 14
The web - irish property - 13

strip out the non-Irish sites and in the Pages from Ireland results you rise to 10th.
