Eek no way i could buy a house with that history.
I agree with mentioning it in the ads could attract people just wanting a stickybeak. Perhaps advertise an open home but not list a time or say open at 10am but please call to register beforehand and inform people then. Saves people a wasted trip but doesnt advertise it. I like the way other people have suggested wording it quite formally, 'I have to disclose due to legislation xyz some history regarding the property etc'.
