My grandma lived in the other end of the country, and when she died last summer at the ripe old age of 98, I went with my family to the funeral and ended up staying in her old house. In her old room. Sleeping in her old bed. It did feel a bit weird, but it wasn't scary in the slightest. Thus, I don't think I'd be too bothered about living in a house where someone died. It's just one of those things people do.
