Never heard of this specific place but the phrasing "something's not right there" is exactly how locals always describe genuinely haunted spots before anyone's done proper research on it. That instinctive unease is worth paying attention to in my experience.
What kind of activity are we talking? Sounds, apparitions, objects moving? I've been poking around haunted locations on Dartmoor for a couple of years now and the farmhouse type locations tend to have the most residual energy, something about all those generations living and dying in the same walls I suppose.
Anyone actually been on the property or is this all secondhand? Makes a big difference. Would like to hear more details before forming any opinion on it.
