Already for you, when the plots are cheap for you.
Of course, that's nice. Personally, I already find €200/sqm really steep. When I then read about €400-700/sqm in certain areas, it almost makes me feel sick.
But even if the plot costs €80,000, I can still stay under €300,000 for everything. Of course, I then have to lower my expectations, but that's the nice thing... not everyone has the same expectations.
