Plenty of sound advice for you to ponder over Crimson.

Other things to consider;
Previous use of the land?
How familiar are you with every inch of the farm? "You need to know every blade of grass by name", was a bit of advice given to me many years ago.
It's no use having hay fields if you can't get the machinery in to harvest the crop due to access problems such as gates being too narrow!
What machinery and other resources do you have available?
How secure is the existing fencing?
Is drainage a problem?
Is water freely available?
Walk the land making notes of potential problems.
"If I rent field x, how would the tenant access the field?",
"How would I get water to field xx?"
"How easily could I access the furthermost part of the estate - in all weathers, and if necessary return with ill/injured stock?"
On the admin side, check with the Rural Payments Agency that the transfer of ownership is recorded with them.
Best of luck with your inheritance, and there will always be plenty of advice freely available to you from the good people on this forum.
Don't be afraid to ask, and remember - there is no such thing as a stupid question.
