In a rural but well maintained area in France, my parents bought recently an old family house for 80k (to which you have to add some renovation costs). In this area a brand new house with a good amount of land is 200-300k. In my own area, a new house is more along the lines of 500k. In any case those things are highly localized here, I imagine it's true in Austria as well (though the country is much smaller than either Finland or France).
