She is primarily a stroke of luck that cannot be generalized like this. If I search on immowelt, I can’t find a 3-room >=80 m2 in Altona for less than 1200 cold rent, typically it’s rather >>1500. Cold!
And those are fixed costs as well.
Look at the prices of cooperative apartments... The rent I mentioned is no isolated case/stroke of luck.
Another friend has been living for 2 years in a 2-room shack behind Max-Brauer-Allee (Altona) for 315 EUR WARM including internet!
Sure, it may be that I only know lucky ones and you only unlucky ones. The truth probably lies somewhere in the middle.
And regarding the listed prices... Well, every new car is advertised with a certain price. EVERY ONE! Please name me even a single person who has ever paid the advertised list price for a car.
Sure, you have to search, dig, rummage, etc... But it’s possible. Of course, if you’re looking for a 100 sqm apartment with a view of the Elbe in Blankenese for 800 warm, then you can search a long time...
