I have to say, I am not a fan of the press getting involved with advertising houses for sale, which is how I assume this came to your attention? It was on the BBC. So many of my local rags are pushing houses for sale in my newsfeed lately. Strangely, I am here for the news.
Anyway, a 145 sq m house with 5 acres that remote MAY be a bargain actually. But if I had the money, still would not buy. They've installed internal or external insulation on a limestone house some time in the last ten years, which is just asking for major, long term damp problems; the water running off that hill is likely to be a flood liability, and you would need constant effort and extreme organisation to run and plan your lives, with everything having to get to it in a 4x4.
It also has the council tax banding of a two bedroom flat, so I imagine once land registry get wind of its current size and acreage, you are probably looking at a reclassification of an E/F some time after you get settled. Is that now automatically done every time a house is sold? Idk. But it shouldn't be a B.
Some stunning original features though.
I wouldn't be worried about being alone too much. Get a gun licence, a gun and a lockable gun cabinet. That's what happens in the countryside. Nobody says you HAVE to use it, but most people approaching a rural property like that would expect the homeowner to have one because almost everyone does.
(sorry for dreary, pragmatic reply)
