So I (also from Berlin) had a standard land value of 420 EUR and paid 492. An asbestos removal cost of 15,000 EUR could be added, so let's say 520 or 100 EUR above BORI. However, I'm still in Berlin (Kaulsdorf) and could walk to the subway. Now it's a year later and when I look at other plots, they are all moving towards 600 and more, with somewhat worse locations. I also find the price a bit high, especially for a house of this size and age. On the other hand, I've seen similar houses for similar prices in neighboring districts of my property. As I said, all from a year ago. I think 600,000 EUR flat should pass. But it also strongly depends on which suburban edge. Roughly give the hemisphere. Do you have access to S-Bahn or BVG (within walking distance)?
