I agree with Marigold. You need to come and see some areas and get a feel for it. Then you'll know where's "right". We'd like more land so have been tentatively looking around but I really don't want to move away from this area, so not much chance of more land.
Saw a nice farm on CKD Galbraith site; Butterhole Farm near Dalbeattie. 11acres wood with blubells, 9 acres of pasture, decent house and yard probably in need of some upgrading. About £400k, I think. Looked lovely and it's a nice part of the world.
