We have been to see a couple of plots, purely Agricultural, no buildings. At sub 5 acres plots, it seems to be around 15k per acre, I do think that's expensive. Looking at South Devon, we are reasonably close you Jonah (if you are still in Torquay)
It seems land is following the route of housing here, places coming up at what me and the missus think are total kite flying prices and yet they "seem" to be selling very quickly, may have wait a year or so and see if it calms downs a bit.
