Renting a field to a farmer A

Would recommend consulting legal advice. Check out an annual lease that automatically expires unless you agree to extend it for another year. Technically, agricultural land cannot have dwellings erected, however "temporary" farm related buildings can be built in some circumstances. This may not be favorable to you.Fred

1.  Agricutlural land can have dwellings in most of Italy - and  for a farmer they're much easier to build than for a mere mortal.  Also in most parts of Italy 1 hectare is the minimum building lot size.  2. As a farmer he has a right to an agricutlural contract which runs for 9 or 11 years adn is renewable.  Your only way to keep some control over the property is to let on an annual lease whci hruns from seeding to harvest.  3 In this latter case, you can also stipulate what is grown and what the land is used for - ie no animals only cereal crops etc.  But dont expect to get huge rents - it will be to all effects free, but the farmer will have to keep it clean and not present a fire risk.  

I don't think that the small rent you may get justifies leasing the land to a farmer who really wants to buy it. Particularly if you wish to keep it as a buffer zone. Not worth the trouble, the legal fees that you may incur and all the aspirin you may have to purchase for headache relief. 

Definitely don't sell it. You have no idea (or perhaps you do) of the horrors that can appear next to your house. On the other hand, having a farmer look after it is quite a good idea. You could lease it year by year for nominal rent on the basis that the farmer deals with the legal costs of the lease. And DO have a lease - if you let him use it in exchange just for a bit of cash and nothing signed, after 10 years or so you could wake up one fine morning and find that it belongs to him!
