The demolition price is realistic. Schönfels Fehmarn recently demolished a building with an asbestos roof for us for 12 including tax, in Husum there is also such a demolition guy who works painlessly. This will work here. The property will definitely be bought, it is a door that won't open again. Build on it and live in it. Financing through the house bank Sparkasse is correct, you know each other, trust each other, in SH there are often uninhabited houses, no need to worry. The idea to leave the basement would be worth considering. Check the new construction costs carefully and critically. It seems a bit tight to me, but only a bit. Not entirely unrealistic. The garden, the driveway, that must be taken into consideration. Here in our neighborhood there are some who first boasted, we'll do the garden ourselves. The fact is, only two manage it for real, one is a professional landscape gardener, the other a carpenter. All the desk workers, however, failed and had to hire companies after all. K.
