It spreads too, in the little towns around Brno prices are raised as relatively wealthy people (who aren't quite able to find something suitable in their budget range in the city itself) seek to buy something near the city and commute or work remotely. I don't imagine the salaries of the people who were previously living in these towns and villages have risen the same way salaries in the city have.
