For the record, I was looking for places to buy in Rotterdam the other month, and what I found was that by and large, if you want to buy things inside the city limits, it's either some weird mansion in the bougie foresty part, a 3 million EUR apartment where your garage is in the apartment, and you enter your place by car lift, or an entire fucking apartment block. People just don't sell cheap apartments piecemeal.
The upside is that living in "the suburbs" which means moderately dense villages and towns near the big cities is doable, and you might be able to commute even without a car since public transport is mostly good.
