There is a famous (among first year law students) case[1] that seems relevant given the nature of the issue is one a buyer would not reasonably be able to ascertain on their own. One possible point of differentiation: ghosts are a permanent defect on the value of the property while loud children living next door would probably only torment the homeowner for a decade or so at most.

The opinion is famous not just for its unusual fact pattern but also because the Judge clearly had quite a lot of fun working in other-worldly puns and references while writing it.
