Still lots of tenancies in Cumbria and Northumberland, but it's tough to get one unless you can really invest. And they don't give long duration ones any more, so that makes it even more expensive. However, if you have money, that talks louder than local knowledge / connections and experience, so you may well be able to find something. If funds are tight, however, I'd say your best bet is to make friends with / work for an unmarried traditional farmer in his fifties or sixties with no succession for the farm!
