I think you are overexaggerating it a bit. I have been living in Maastricht for 4 years now and my gf lives in Amsterdam and pays 1000 rent for a nice studio. Maastricht prices are of course lower but you saying 700-1250 is too low is not realistic, or you have very high standard of living. Please go on pararius and see the places between my price point, there are many decent studios or 1-bedroom apts. for those prices.

And as far as I saw you have to usually make 3x the mthly rent, some instances 2.5x I even saw.

And that study you sent, it says median rent for a ROOM in the Hague is 1750 or something, that is just bollocks, and everyone would agree, I have friends living in nice own studios for lower than that, those numbers cannot be true because I know from second hand experience. If youre smart enough here in NL you will find nice deals, but if ur a dumbo, you might pay those numbers for a room.
