How many houses that have been standing for a while are likely to have no history of death? Lots and lots of people die in houses, of causes of all kinds. And in hotel rooms, too. (Not to mention rooms in care facilities.) Unless you are living in a new place or one with a short history that you actually know, you could very well be living where someone has died.
A building is just a building. In terms of nature and the world, its boundaries don’t really have any meaning; they just enclose space. Assuming that no visible physical reminders remain, how could being in an enclosed space where someone has died really be significantly different from being in an enclosed space where someone did not die? What if they died in the next enclosed space—the next room, the next apartment, the next house?
When my husband bought our house, he heard that the old man who used to live here had hanged himself in the garage. However, the garage is not haunted. There is no sign of the old man.
Years ago the next-door neighbors were murdered with automatic weapons in some sort of drug-related vendetta (we never knew the details). A few days later the landlord cleaned up, patched the holes, replaced cupboard doors, and repainted. The new tenants never knew a thing.
