Oop, make that “anything that may affect the buyer’s decision to purchase or the price”.
…to disclose the presence of a ghost? Can failure to notify the prospective buyer be grounds to void the sales contract? Suppose you havea house where somebody was killed-and his ghost shows up every dec.4 -are you bound to disclose the haunting? 
Some chalk outlines are more common than others…
We’re in California, and we found out about the house next door because our real estate agent was obliged to include the information in the disclosure packet for the house we were thinking of buying (and eventually bought).
That’s why I’m an agnostitic.
Definitely.
