If you are new to the area it's also good to do a bit of homework too----who is who and what kind of reputation they have----take a look over his fence and see what his sheep look like. If his farm is a mess do you really want him on your land?
agree with this. our neighbour is a tenant and although his sheep are well looked after, he collects and hoards things on the land which ends up spilling onto my land. theres a fair bit there, empty feed buckets/bags, wood, fleeces, trailers, landrovers, rubbish, the list goes on...
why not just try and bargain a wee bit, raise him £50 quid? a friendly farmer is a great help when you need the roads cleared of snow / hay delivered or theres a lambing emergency. try and get a fencing lesson off of him while he's there unless you know how to do it already.
