my advise would be to contact several estate agents in th earea where you live (or where you want to live)
tell them what you are after, your budget etc - and let them keep an eye out for something suitable on your behalf (some work better than others)
they might also know of a property with no land but adjacent to land that you might be able to lease of the landowner (especially if it isn't being used)
1st step would be to contact the landowner and see if he's open to leasing it
have you got a local smallhoders association, contact them, they might be able to give you some pointers/local info - you may even find one has more land than he can manage and would be willing to share a bit in return for your time effort
