Would work be in Wexford general? There isn't a huge selection in that price range, but have a look around Clonard village, Whiterock or Cromwell's fort. All recent builds, and decent areas.
Otherwise in town you'd be looking at an older terrace in need of work, or an apartment.
Is increasing budget an option, and taking in a lodger? Even a small increase would open up options a bit to a proper 3 bed semi in Clonard proper.
Outside Wexford town I can't think of any suggestions that aren't going to be a bit remote for an outsider. Castlebridge maybe, but budget would be tight.
