250K won't get too much in many areas. I'd choose Mexico, but you can't buy on the shore directly. The southern tip of Nova Scotia would be my second choice, but the money wouldn't stretch anywhere bear as much. Don't know about prices in Australia, but that would be a third one that I think you could try, just don't expect to be in the city. Maybe Rio De Janeiro. Don;t know of another place on the shore that I would want to be with only 250K.
