Permaculture North/East Slope Germany – Buy or Pass?

Hi everyone,

We are currently contemplating the purchase of a 8100m² property in Germany (a few kilometers north of the Harz mountain range). Our main concern is the fact that the property is on a north/east (20° to east) facing slope – house at the top. The highest point of the agricultural area of the property is at ca. 165m above sea level, and the lowest point is at ca. 153m above sea level. The distance between those two points is about 50m (+/- 3m) with varying gradient (some parts quite flat, some steeper) . The lowest part is already used as a field by a farmer; the upper parts have been used by the previous owners. They had a small vegetable garden and various fruit/nut trees (hazelnuts, walnuts, etc.).

The house is on a small plot of ca. 300m², the rest is pretty much all supposed to be used for permaculture with the goal of self-sufficiency. Our main concern is the potential lack of sun to get anywhere near our goal. Any thoughts and/or advice?
