I don't know how old your house is, if it is older than 50 yrs chances are high somebody died there simply because it was normal in former times to die at home. We owned an 1893 Victorian and it is almost guaranteed that someone died there at one point. If you are asking of there was some kind of a violent death you can always do research online with the address or the name(s) of former owners. In most states it is not required to disclose a death in the house. In some states it ahs to be disclosed if it was under certain circumstances or recently (last x years).
