Such disclosure laws are silly.
Maybe for people consumed with things like the idea that buildings are haunted, thinks their lives are being affected by spirits (no, not the liquid kind), reveres saintly images in burnt tortillas and water-damaged ceiling panels, and believes and/or pays for psychics etc, it could be a purchase issue … but hey, that’s what ghostbusters are for.

My house is an 1892 and for a 70 year period starting early in the last century has periodically been a multi family rental. How many people have lived in my house since it was built … died in the house … crimes? … I have no idea.

The home two houses down from mine was built in the 1840’s. Where I used to live there was a house about 1/3 mile away that was built in the 1790’s.
It seems pretty tenuous to make a legal issue out of deaths in a structure.

More ridiculous laws … but who are we to question the LAW right??
