Moving next year to UK

Hey, I’m 22% Irish and want to move to County Cork (I’m a Kennedy on my maternal side). So I was reading that my folks came over during the potato crop failure. How much money would I need to come and buy a house?

Currently 31 with $5M in stock options I could liquidate, would this get me a property with land in county cork, I want to farm but have no experience, I’m thinking some goats and sheep on like 200 acres. Also, could I take my RAM 3500 over?
