Maybe we could think of it like : in DE the rents are still cheap and the wages are high enough to lower the urge to access ownership, also compared to France for example it is easier to get a rental. They won’t ask you for so many guarantees and background checks etc… these factors might play their part too. In some EU countries , depending on your ethnicity, job sector, ability and so on it is sometimes easier to buy than to rent at the end of the day.
