Thank you for your participation, but it's a pity that my thread here has turned into a general discussion about the sense of real estate investments. For me, they make sense, even though I rent.
Let me put it this way: if you calculate the net return correctly and correctly assess the backlog of repairs or the condition of the property(ies), then you should buy it immediately. However, the 7% does not match your other information – because such a return is only achieved in top locations, if at all.
I would say you are wrong here. I read the following in a real estate book, which has been confirmed by my return research: In top cities and/or top locations, you have
less net return than in poor locations! Why? The enormous purchase prices of the properties! Rents do not grow with purchase prices! You pay the high purchase prices in top locations like downtown Düsseldorf
also because this property has the potential to appreciate in value. On the outskirts of Herne, you don't have that. You buy the high (currently still existing) rental yield with the risk that the value of your property and the rents may decrease.
If Herne is actually shrinking, then demand is also declining. The crucial point is then where exactly the city is shrinking or where your micro-location is or how it is developing compared to other districts.
And exactly that I find very difficult to predict, no matter the city.
